I. INTRODUCTION

1. Manesar is a village located on National Highway 8. It is about 16 KM from Gurgaon in the North East direction. Location map of Manesar is at Map 1. NCR Regional Plan has identified Gurgaon Manesar complex and accordingly Government of Haryana has prepared combined master plan for Gurgaon Manesar complex for the year 2031. Land use as per the master plan is given in Map 2. Haryana State Industrial Infrastructure Development Corporation (HSIIDC) has developed Industrial Model Township in Manesar comprising sectors:

a. Residential Zone sector 1,1D & adjoining area b. Industrial sector 2 to 16 & along villages c. Some Commercial areas and villages

2. Manesar is a fast growing industrial town in Gurgaon district of the State of Haryana in India, and is a part of the National Capital Region (NCR) of Delhi. Geographically, Manesar is located at 28.57°N latitude and 77.23°E longitude. Industrial model Town (IMT) Manesar is developed in four phases on about 3,400-acre. Manesar has been developed by Haryana State Industrial Infrastructure Development Corporation (HSIIDC), Phase I (1748 acres) launched in 1997-98, Phase II consist of 175 acres, Phase – III consists of 598 acres and Phase – IV consists of 657 acres. HSIIDC has developed Phase-I, while work is in progress in Phase-II and Phase-IV. HSIIDC has allotted Phase-III (600 acres) to Maruti Udyog Limited for their expansion project. Manesar is an Integrated and Independent Industrial town having all the basic infrastructure to facilitate Industrialization of the area. The facilities include Hi-tech Telecommunication, 220kV Power Substation, Water Supply, Sewerage disposal, Helipad, Shopping arcades, Health centers, Schools, Wide metallic roads, Golf Course and Clubs. 3. HSIIDC is a Public Limited Company owned by the Government of Haryana (GoH), instituted and established in 1967. HSIIDC is the nodal agency for development of Industrial Infrastructure in the State of Haryana. After acquisition of land through the Department of Industries, GoH, the Corporation prepares a detailed plan for its development and thereafter executes various development works such as Construction of roads, Water Supply System, Sewage, Drainage and Electrical Infrastructure. This is followed by provision of secondary level of facilities such as the STP/ CETP, Development of Plantation/ Green belts, Commercial and Institutional sites, Common Parking facilities, etc. In this process, the Corporation has developed Industrial Model Townships (IMT), Industrial Estates and Industrial Clusters (Theme Parks) at strategic locations and framed its own internal set of guidelines for their governance. 4. Groundwater & surface water from Gurgaon Water Supply (GWS) canal are the sources for water supply in Manesar. At present about 15 MLD water is extracted from tube wells drilled in various parts of the town and about 20 MLD water is supplied daily from GWS canal water source after treatment. The GWS has been tapped at its tail end at village Basai and then pumped to sector 7 of IMT Manesar where water treatment plant exists. The existing water supply system is operated and maintained by HSIIDCs own staff except that the WTPs O & M is privatized under HSIIDC. HSIIDC is operating and maintaining water supply schemes in all Industrial areas in Haryana since creation of industrial areas. 5. The water demand for IMT Manesar developed in 4 phases stated above is 175 MLD as shown in Table 1 This requirement will be met from different sources as stated in Table 2.

6. The existing canal water supply system with capacity of 20 MLD needs to be augmented to 125 MLD to meet the demand stated above. This will be done by enhancing capacity of existing canal water supply system from 20 to 35 MLD and installing new canal water supply system of 90 MLD. The new system of 90 MLD will be achieved in two sub phases, each of 45 MLD. The current sub project is for sub phase 1 of 45 MLD and enhancing capacity of existing canal water supply system from 20 to 35 MLD. Thus the current project is to augment existing water supply from canal level of 20 MLD to about 80 MLD. The project details are shown in Maps 3 and 4. 7. This Initial Environmental Examination (IEE) report is prepared in accordance with NCRPB Environmental and Social Management System (ESMS) and Policy for project funding.

II. POLICY & LEGAL FRAMEWORK

A. Extent of IEE Study 8. The subproject implementation shall comply with the policies of Government of India (GoI), Government of Haryana (GoH) and procedures/policies of NCRPB. Government regulations and the NCRPB policy require that impacts of the development projects have to be identified at the beginning and mitigation measures be incorporated in the project to reduce those impacts to acceptable levels. This is generally done through the process of environmental impact assessment. B. Government Laws and Policies 9. The GoI EIA Notification of 2006 (replacing the EIA Notification of 1994), sets out the requirement for Environmental Assessment in India. This states that Environmental Clearance (EC) is required for specified activities/projects, and this must be obtained before any construction work or land preparation (except land acquisition) may commence. Projects are categorized as A or B depending on the scale of the project and the nature of its impacts. 10. Category-A projects require EC from the Ministry of Environment and Forests (MoEF). The project proponent is required to provide preliminary details of the project in the prescribed manner with all requisite details, after which an Expert Appraisal Committee (EAC) of the MoEF prepares comprehensive Terms of Reference (ToR) for the EIA study. On completion of the study and review of the report by the EAC, MoEF considers the recommendation of the EAC and provides the EC if appropriate. 11. Category-B projects require environmental clearance from the State Environment Impact Assessment Authority (SEIAA). The State level EAC categorizes the project as either B1 (requiring EIA study) or B2 (no EIA study), and prepares ToR for B1 projects within 60 days. On completion of the study and review of the report by the EAC, the SEIAA issues the EC based on the EAC recommendation. The Notification also provides that any project or activity classified as category B will be treated as category A, if it is located in whole or in part within 10 km from the boundary of protected areas, notified areas or inter-state or international boundaries. 12. None of the components of this canal based water supply project in Manesar fall under the ambit of the EIA Notification and as such EC is not required. C. Environmental and Social Management System of NCRPB 13. Recognizing the importance of environmental and social issues that can arise in infrastructure projects, NCRPB has formulated an Environmental and Social Management Systems (ESMS) in line with Government and other multilateral agencies like ADB safeguard requirements for Financial Intermediaries (FIs). The ESMS provides an overall management system to NCRPB to identify, assess, and mitigate environmental and social issues that are likely to arise in projects funded by NCRPB. The ESMS outlines the policies, methods of assessments and procedures that will enable NCRPB to ensure that a project that it funds is developed in accordance with ESMS and is adequately protected from associated risks. Implementing Agencies (IAs) will have to comply with the ESMS and Policy.

1. Environmental Policy

14. Policy Statement. “National Capital Regional Planning Board (NCRPB) will continually strive to ensure and enhance effective environmental management practices in all its operations”. This is aimed to achieve through:

Minimizing negative environmental (including health & safety) impacts in its operations and risks to the environment (particularly eco-sensitive areas and culturally important areas) and people who may be affected through formulating and implementing commensurate plans

Ensuring that environmental safeguards - defined as requirements of applicable Indian environmental legislation and multilateral / bilateral funding agencies - are being adequately integrated by the project proponent / IA in the planning, design, construction prior to its financing and in its implementation during the operational phase.

Ensuring compliance to all applicable national and local environmental legislation.

Encouraging that public and stakeholder consultation be carried out by the project proponent / IA and disclosing the required information at all stages of the project cycle.

Integrating environmental risk into its overall internal risk management analysis.

Including environmental management considerations in all aspects of operations and interactions with the project proponent / IAs in all stages of the project cycle.

15. This policy statement emphasizes NCRPB's sensitivity, concern and commitment to environmental safeguards. NCRPB will strive to ensure that the projects that it supports meets government policies and as well as of the bilateral/multilateral agencies such as ADB.

2. Environmental Assessment Requirements

16. The nature of the assessment required for a project depends on the significance of its likely environmental impacts, which are related to the type and location of the project, the sensitivity, scale, nature and magnitude of its potential impacts, and the availability of cost-effective mitigation measures. According to NCRPB ESMS, the projects are screened for their expected environmental impacts and are assigned to one of the following categories: E1, E2 or E3.

Table 3: Environmental Category

Environmental Scenario NCRPB’s

Categorization MOEFs

Categorization ADB

Categorization

Significant impacts or in eco-sensitive area E1 A A

Limited impacts E2 B1 or B2 or No

Category B

No impacts E3 No Category C

(i) Significant impacts or in eco-sensitive areas (Category E1): If the project has

significant adverse environmental impacts that are irreversible, diverse, or unprecedented, then it is regarded to have environmental scenario. These impacts may affect an area larger than the sites or facilities subject to physical works. These impacts will be considered significant if these are in eco-sensitive areas.

11

(ii) Limited environmental impacts (Category E2): If the project has impacts that are site-specific, few if any of them are irreversible, and in most cases mitigation measures can be designed.

(iii) No environmental impacts (Category E3): If the project is likely to have minimal or no adverse environmental impacts, then it is regarded to have this environmental scenario.

17. The proposed project site is not located or near any eco-sensitive area. The subproject is however likely to have typical impacts associated with the construction activity in urban areas and therefore classified as Category E2. 18. According to ESMS, E2 projects require carrying out Initial Environmental Examination (IEE) and preparation of IEE Report. This IEE report is prepared accordingly.

D. NCR Regional Plan Policies 19. Revised Regional Plan 2021 has delineated Natural Conservation Zones in NCR in which following uses/activities are permitted:

a. Agriculture & Horticulture b. Pisciculture c. Social forestry/plantation including afforestation d. Regional recreation activities with no construction exceeding 0.5% of the area

20. The WTP area proposed near village Harsaru has Natural Conservation Zone1 nearby and the proposed intake structures, WTP site & IMT Manesar are not under NCZ. Earlier it was under Special Economic Zone (SEZ) land but subsequently SEZ was cancelled & taken over to HSIIDC for public water works. At present in about 6 acres area raw water reservoirs and pumping stations are in operation at proposed WTP site in Harsaru. There is no conservation area like a Nature Reserve, Sanctuary, National park or other area of Ecological importance close to proposed WTP site. As such exact location of WTP site which is about 100 acres has been plotted on NCR map showing land use zoning. Harsaru WTP proposed site is on junction of Pataudi road and Northern peripheral road (V2 (a)) and in sector 36 B of Gurgaon Maresar Complex Master Plan 2031. The location in terms of latitude and longitude of outer edges of Harsaru plot boundary are as follows:

Latitude 280 25’48.63” Longitude 760

57’42.59”

Latitude 280 25’35.36” Longitude 760

57’45.52” Latitude 280 25’35.03” Longitude 760 58’5.45” Latitude 280 25’59.6” Longitude 760 58’5.86” Latitude 280 26’1.83” Longitude 760 58’2.15”

1 As per “Chapter 17 - Regional Land Use” of Revised Regional Plan-2021 “17.4.3 Natural Conservation Zone”: Major

natural features identified as environmentally sensitive areas are Aravalli range in Rajasthan and Haryana Sub-regions and its extension as the Ridge in NCT-Delhi, forest areas, rivers and tributaries of Yamuna, Ganga, Kali, Hindon and Sahibi, sanctuaries, major lakes and water bodies such as Badkal lake, Suraj Kund and Damdama in Haryana Sub-region and Siliserh lake in Rajasthan, etc. These areas have been demarcated as Natural Conservation Zone in the Regional Plan-2021. Similarly, ground water recharging areas such as water bodies, ox-bow lakes and paleo-channels have also been identified. These areas are to be further detailed out in the Sub-regional Plans and Master/Development Plans.

Latitude 280 25’57.61” Longitude 760

57’54.19” 21. The WTP site is under built up area and not in NCZ (Refer; Maps given in Annexure 6 – 8). WTP site looks to be surrounded by NCZ but important thing is that it is under built up area & not under NCZ and as such NCZ requirements do not apply. To make matter clear now attaching RP--2021 existing land use plan & proposed land use as per RP-2021 and as per Sub Regional Plan of Haryana and as per master plan of Gurgaon Manesar complex.. There is no overlap of the 'built up area' and the NCZ area. The two areas are in fact two separate land use zones.

III. DESCRIPTION OF THE PROJECT

A. Project Need 22. Water supply in Manesar village is supplied by PHED Haryana. Water supply in IMT Manesar which has been developed near village Manesar is supplied by HSIIDC. Haryana Urban Development Authority2 (HUDA) is responsible for water supply in sectors developed by HUDA. Tube wells have traditionally been the main source of water in Manesar. At present there are 45 tube wells, from which 15 MLD of water is supplied. Water is supplied directly from the tube wells into the distribution network. Distribution system in HSIIDC areas has been laid on sectoral basis and water is received in ground level reservoirs and then pumped to OHSRs from where it is supplied through distribution system. Disinfection of water is done by chlorine. 23. The existing tube wells are demonstrating a marked decrease in yield and deteriorating water quality. At few places, the ground water quality has become un-potable. Accordingly, the existing water sources are unable to meet the peak summer season demand. Extensive ground water usage for domestic as well as commercial and Industrial use was observed to be a common phenomenon in Manesar and the adjoining areas. The level of the water table is reported to be sharply depleting during last 5 years, resulting in declining yield from existing tube wells. Ground water in and around Mansear is over exploited. 24. The water supply system of IMT Mansear has not been given any comprehensive look for improvement in the past. The approach seems to have been mostly ad-hoc. Construction of additional tube wells to meet increased demand or construction of new tube wells as replacement against failed tube wells has been the practice. 25. Efficiency improvement in transmission system has been considered while optimizing pumping. Distribution system of treated water is not in scope of this sub project. The cost recovery is 100% and all consumer meters are functional. The existing NRW levels are low. Pumping has been optimized. DI pipe proposed to reduce losses in transmission system. Also O & M privatized for better O & M so as to minimize water losses 26. The water demand planning for future has been worked out considering reuse of treated waste water. Sewage treatment plant of 15 MLD capacity is existing and its capacity is being enhanced and additional STP is under construction. These measures will increase STP capacity to 55 MLD. The treated effluent is used as i) Tanker transporters take treated waste water from the hydrant near STP and pay for it & use where possible, ii) pipe line has been laid in median

2 HUDA is an autonomous government body and functions as the land developer in Haryana.

13

of existing roads in which treated waste water flows and it is used to irrigate plants in the road median, iii) the surplus effluent is disposed through effluent channel which finally leads to Badshahpur drain. 27. Budhera is tail end of NCR channel and Basai is tail end of GWS channel. Budhera is about 4.62 KM up stream of Basai. The existing water supply system for IMT Manesar is from Basai from GWS channel. Under the new system water is to be drawn from Budhera as NCR channel ends here. Also to use available land at Basai it is proposed to construct RCC box channel from Budhera to Basai along the GWS channel & in the land allocated for GWS channel. Length of this channel will be 4620 m. The slope proposed is 0.015% & thus the total fall will be 0.693 m. This channel will be for final requirement of 120 cusecs. Channel size will be 6 m*1.62 m. Open channel is not proposed in this reach to prevent theft as at present there is theft in GWS channel in this reach. This work will be done by the Irrigation Department as per the estimate prepared by the irrigation Department. Sufficient right of way is available along existing GWS channel to accommodate box culvert. B. Description of the Subproject 28. HSIIDC has developed infrastructure to draw 12 cusecs of water (29.36 MLD) from GWS canal from Basai. The authorized quantity of water for HSIIDC from GWS canal is 12 cusecs. At present HSIIDC is drawing about 20 MLD water from GWS canal against the sanctioned quantity of 29.36 MLD water as the present system can supply 20 MLD water only. 29. GWS canal was constructed by Irrigation Department of Haryana many years ago basically for drinking water of Gurgaon city and other reroute towns/villages. This canal does not have spare capacity. Therefore, Haryana conceived NCR channel of 500 cusecs capacity in Phase-I to meet requirement of PHED, HUDA and HSIIDC. Gurgaon Manesar Urban complex. HSIIDC reserved 317 cusecs water in NCR channel for IMT Manesar, Sohna Industrial area and other demand of HSIIDC. HSIIDC, PHED & HUDA have shared cost of NCR channel in proportion to their requirement. HSIIDC vide letter IA:2010:251 dated 20-04-2010 informed Irrigation department the takeoff points with quantity of water as follows:

a. 110 cusecs of water at Badli at RD 52.400 KM b. 120 cusecs of water near village Mundakhera at RD 64.500 KM c. 120 cusecs of water at Budhera at RD 70.700 KM

30. The water to be tapped at Budhera is for Sohna and IMT Manesar and other adjoining areas of SEZs. The water demand of IMT Manesar is as follows:

Table 4: Water demand for IMT Manesar in Phase-I and Phase-II Water demand for IMT Manesar in Phase 1

Residential Zone sector 1,1D & adjoining area 25.76 MLD

Industrial sector 2 to 16 & along villages 147.89 MLD

Commercial areas 0.86 MLD

Village areas 0.02 MLD

Total 175 MLD

Water demand for IMT Manesar in Phase 2

Additional area across KMP highway 73.48 MLD

Area reserved for public & semipublic use 37.78 MLD

Total 111 MLD

14

31. Out of 175 MLD in Phase-I, 125 MLD will be Canal water, 15 MLD from tube well and 35 MLD is treated wastewater. Out of 111 MLD in Phase-II, 89 MLD will be from canal & 22 MLD from treated wastewater. 32. To take 125 MLD water from canal for IMT Manesar, existing water drawl from canal (20 MLD) will be strengthened to 35 MLD and additional 45 MLD system will be developed under Sub-Phase-I. Subsequently further 45 MLD system will be developed under Sub-Phase-II. As stated in demand under both phases 25.76 MLD water will be used for residential sectors and remaining for industries/commercial. The final requirement of drinking water for IMT Manesar is 286 MLD. 33. Dependability of local ground water has greatly reduced and it has come under over exploited zone. The quality of ground water in Manesar is deteriorating making it unfit for human consumption in parts of the town. The quality of raw water in the canal is good and treatable. This canal water is already a source for many towns and villages including Gurgaon. 34. This subproject is designed with NCR Channel as source. The project is for raw water conveyance channel, raw water storage & sedimentation tanks, raw water pumping, WTP, Clear water pumping, transmission main, etc. Also included is strengthening of the existing canal based water supply system. Distribution network, service reservoirs and internal transmission system has been already developed for sector 1 to 7 & as such not included in this project. Existing Infrastructure for IMT Manesar

35. Basai Head Works: Water from GWS canal is drawn at Basai which is dead end of this channel. Area of land available is 6.5 acres. At present HSIIDC has, Raw water storage tanks 2 no capacity 12 ML, boundary wall, guard room, Pumping station, control room, pumps 2 number, Mather platt each 12 cusecs at 17 m head with 120 HP induction motor, DG set 240 KVA Kirloskar and 600 mm DI pipe line from Basai to Harsaru. Water from Basai is pumped to Harsaru (Annexure 10 & 11). 36. Harsaru Water works: Area of land reserved by HSIIDC for development of water supply is 100 acres. Some part of land about 10 acres has been used for construction of Northern peripheral road. This land is vacant but part of it about 6acres is occupied for existing water supply system. Raw water storage tanks 2 no capacity 31 ML, boundary wall, guard room Pump house, control room, transformer room, Centrifugal pump 2 number, Mather platt each 12 cusecs at 53 m head with 180 HP induction motor, DG set 240 KVA Kirloskar are existing at present.

41. Distribution system has been laid for most of the sectors with 30 year design period. Distribution system is not part of the current project. Where required the distribution system will be laid by HSIIDC from their own resources. Rehabilitation of Existing Canal Water Supply System

42. The existing canal water supply system emanating from GWS Channel at Basai will be strengthened to supply 35 MLD water. 43. Basai Head Works: The existing 2 no tanks (45m*45m and 45m*40m) at Basai would be rehabilitated. Bed lining and side lining of the tanks are badly damaged due to rise in water table, the water table is at 210 m level and bed level of the tanks is 205.18 m. The general water table in the area, which is at 210 m level, shall be lowered & then repairs will be carried out. Silt deposited at base will be removed. The bed level will be raised by 1.82 m (1.22 m granular sub base and 0.25 m slab + 0.35 m plum concrete) to reduce uplift pressure. 44. Replace existing pumps at Basai: It is proposed to provide two new pumps of 250 LPS at 38 m head & of 175 HP of which one will be stand by. Also one number generating set of 400 KVA will be provided 45. Renovation of existing slow sand filters and Development of waterworks at sector 7 & 3 by renewal of existing pumps 380 LPS at 65 m head 320 BHP, 2W+1S and generator 750 KVA is proposed. Expansion of Canal Water Supply System

46. Box Channel: Budhera is tail end of NCR channel and Basai is tail end of GWS channel. Budhera is about 4.62 KM up stream of Basai. The existing water supply system for IMT Manesar is from Basai from GWS channel. Under the new system water is to be drawn from Budhera as NCR channel ends here. Also to use available land at Basai it is proposed to construct RCC box channel from Budhera to Basai along the GWS channel & in the land allocated for GWS channel. Length of this channel will be 4620 m. The slope proposed is 0.015% & thus the total fall will be 0.693 m. This channel will be for final requirement of 120 cusecs. Channel size will be 6 m*1.62 m. Open channel is not proposed in this reach to prevent theft as at present there is theft in GWS channel. This work will be done by the Irrigation Department as per the estimate prepared by the irrigation Department. 47. Options: Various alternatives to transport canal water to Manesar were considered. However, the fact that 100 acres of land is available at Harsaru to accommodate storage and sedimentation tanks for 7 days storage, 6.5 acre land is available at Basai & strip (15 m wide) of

50. HSIIDC has 100 acres of land. Small part of it, about 6 acres has been used for existing canal based scheme for Manesar. Now WTP has been proposed at Harsaru as the adequate land is available here. Treatment plant required in Phase-I is of 90 MLD. However WTP will be developed in two sub-phases, each sub-phase of 45 MLD capacities. However the other systems such as raw water reservoirs are being developed for 90 MLD (Annexure 10 & 12). 51. Raw water will be received in stilling chamber 12 m*12 m*4 m SWD to reduce velocity head. Raw water from here will flow to three raw water storage tanks with 7 days detention time to take care of water supply during canal closure periods due to maintenance shutdown of the canal. Storage of 2 hour for developer’s area has also been provided. Size of tanks proposed is 235 m*190 m, 235 m*335 m, 180 m*350 m at top. Capacity of these tanks shall be 1051 ML. Water depth will be 6.23 m. 52. WTP will comprise Flash Mixer, Ventury Flume, Alum solution tanks, Lime solution tank, Clarifloculator 2 no 15 m dia 3 m SWD, 12 twin filter beds 5.7 m* 4.6 m* 3.8 m depth, clear water reservoir of 2 hour detention time, 2 no 37.5 m* 25 m, 3 m SWD, clear water pump house 15m*6 m. Staff quarters will also be provided. 53. Water from clear water pump house will be pumped from Harsaru to Sector 7 & Sector 3 Manesar through 800 mm DI pipe line. Length from Harsaru to sector 7 is 9000 m and Harsaru to Sector 3 is 10500 m. Rail line & highway crossings shall be provided. Three working pumps and one standby pump of 260 LPS at 65 m mead and 320 HP will be provided. Generating set of 750 KVA shall be provided. 54. Development of waterworks at sector 7 & 3 will be done by laying 600 mm DI pipe 3000 m, 500 mm DI pipe 1500 m & 400 mm DI pipe 1500 m. Pump House of 158 Sqmt area shall be provided with Centrifugal pumps 380 LPS at 30 m head 220 BHP 3W+1S. Generator 750 KVA is also proposed. 55. Tube well source: No new tube wells have been proposed. 56. Distribution system and overhead service reservoirs in most of the sectors have been developed with ultimate demand and in some sectors or left out works will be taken up by HSIIDC under their own funded scheme. 57. The site selected for construction of Channel is along existing GWS canal & earlier it was proposed to acquire strip of land 2.65 acre (channel construction work entrusted to

17

Irrigation department). HSIIDC is contemplating change in design to avoid Land Acquisition (LA) for channel & discussing with Irrigation department to construct channel in existing available land of GWS Canal (GWS canal is under Irrigation Department of Haryana) without any LA. For other structures land is already in possession of HSIIDC and LA is not required. Occupational Health & Safety 58. Operation of Water Treatment Plant (WTP) involves various processes: a conventional treatment plant involving Clariflocculation, Rapid Sand Filtration and Chlorination, Clear Water Storage and Pumping Arrangements, etc. The backwash from the rapid sand filters is proposed to be brought back into the raw water storage tanks, thereby avoiding the problem of its disposal into surface water bodies or on land. This is a progressive approach which has been adopted by HSIIDC in almost all its water works and which helps in conserving a substantial quantity (about 2-3%). Total land area required for construction of this composite WTP work is about 90 acres and a place has been earmarked for disposal of sludge in WTP area itself. Thus it will not create any serious environmental issue during maintenance. Chemicals such as Alum and Chlorine will be used in the treatment processes. 59. The Preliminary design recommends inclusion of a clarifloculator which may generate alum sludges, with solid concentrations varying from 0.25 to 10%. Sludge which accumulates on the bottom of the sedimentation basins will be removed periodically for the following reasons:

i. to prevent interference with the settling process (such as re-suspension of solids due to scouring);

ii. to prevent the sludge from becoming septic or providing an environment for the growth of microorganisms that create taste and odor problems; and

iii. to prevent excessive reduction in the cross sectional area of the basin (reduction of detention time).

60. Backwash water will be diverted to open reservoirs and supernatant will be pumped back to water treatment plant. After reasonable accumulation of sludge in the reservoir, it will be pumped to sludge disposal/management area. No effluent will be released from the WTP. 61. There is invariably a safety risk when considerable quantities of chlorine are used to disinfect the water. Thus precautions will be needed to ensure the safety of both workers and citizens. The average dose of chlorine for pre-chlorination will be about 4mg/l and that for post-chlorination will be about 2 mg/l. About 480 kg of chlorine will be consumed daily. 62. Chlorine equipment and storage will be provided in chlorination plant, which will be developed with all safety features and equipment to meet with any accidental eventuality. The chlorination plant will comprise a chlorinator, container store, vehicular access, mechanical container handling facility and a chlorine neutralization pit with a lime slurry feeder. The container store area and chlorinator room will be made in house and provided with continuous forced ventilation system as well as provided with facility for isolation in the event of major chlorine leakages. Safety equipment will be provided to the plant operators in the chemical house as well as in the chlorine house. Visible and audible alarm facilities also to be provided in the event of chlorine gas leak. A separate office building cum laboratory shall also be provided. 63. Training will be provided to the staff in safe handling and application of chlorine. This will be included as part of WTP turnkey contract. Each chlorinator will be provided with standard

18

operating manuals for safe operation and as well as maintenance and repairs. With all the safety features included in the design, the health and safety risk due to handling chlorine will be negligible.

IV. DESCRIPTION OF ENVIRONMENT

A. Physical Resources

1. Location

64. Manesar lies in the Gurgaon district of the Haryana state in the Northern part of India. Geographically, Manesar is located between 28.57°N latitude and 77.23°E longitude. Average N.S level of area is 200 - 220 Mtr. above MSL and all towns/villages of districts are well interconnected by road network. More than 100,000 people go to work in Manesar from adjoining places. The Gurgaon-Manesar Master Plan projects the population of 37,000,000 by 2021. Manesar is 32 km from IGI Airport and is just 16-23 km from Gurgaon and has some of the best urban infrastructure in Northern India. Located on National Highway 8, is served by local buses and trains plying on this route. The area is well connected with Delhi, Rewari, Dharuhera, Jaipur, Ahmedabad and Mumbai; air connectivity is equally good. The nearest railway station is Ghari Harsaru (GHH) and renowned station is Gurgaon. 65. Manesar is “Flagship Industrial Park” of the state of Haryana, developed in four phases on about 3,400-acre. Manesar has been developed by HSIIDC, Phase I (1748 acres) launched in 1997-98, Phase II consist of 175 acres, Phase – III consists of 598 acres and Phase – IV consists of 657 acres. Following table gives the 8 sectors details

2. Topography, soil and geology

66. The major part of Gurgaon district is underlain by Quaternary alluvium consisting of sand, clay and silt. The quartzite ridge trending NNE-SSW is located about 7 km east of town in which ground water occurs in fractures, joints and crevaces. Sandy layers at various depth form major water bearing horizons above the crystalline basement. Ground water in the block occurs in unconfined and semi-confined condition. The upper zone of saturation consists of fine sand with silt varying from place to place. In Udyog vihar and city area the depth of first aquifer varies from 34 to 43 m Below Ground Level. However in industrial area of Manesar top most aquifer can be encountered at 20m. The thickness of sandy layer is very limited. The draw down is generally high indicating absence of highly potential ground water bearing aquifers. Tube wells in the depth range of 45 to 90 m below ground level have been installed by different agencies in the block. The yield of these tube wells varies in different areas ranging within 129 to 606 lpm. 67. The area is conspicuously flat topography; however, in the North-Eastern part small isolated hillocks of Precambrian rocks are exposed. The alluvial plain is formed by the Sahibi

19

river which is tributary of River Yamuna. Soils of the Gurgaon district are classified as tropical and brown soils, existing in the North Western Extreme, Northern and North Eastern parts of the district and water logged and salt affected soils in the Southern parts of the district. The soils are medium textured loamy sand is the average texture in Gurgaon and Sohna blocks. In Pataudi and Sohna blocks the organic content of soils is lowest, just up to 0.20 per cent (very low category). In the rest of the district, organic content is 0.2 to 0.40 percent and falls in low category. The Gurgaon district is occupied by Quaternary alluvium and Pre-Cambrian meta- sediments of Delhi Super Group. The alluvium comprises of thick beds of fine to coarse-grained sand with alternating layers of thin clays.

3. Climate

68. The climate of the district can be classified as Tropical Steppe, Semi-Arid and Hot which is mainly characterized by the extreme dryness of the air except during monsoon months, intensely hot summers and cold winters. During three months of south west monsoon from last week of June to September, the moist air of oceanic origin penetrate into the district and causes high humidity, cloudiness and monsoon rainfall. The period from October to December constitutes post-monsoon season. The cold weather season prevails from January to the beginning of March and followed by the hot weather or summer season which prevails up to the last week of June. The mean daily maximum temperature is about 41°C in the months of May and June. It may go up to 45°C or more in June. During winter the mean daily maximum temperate in January in 21°C and minimum is about 3-4°C. May and June are the hottest months and January is the coldest month. 69. The district experiences dry air except during the monsoon, hot summer and cold winter. The average annual rainfall for the five years i.e. 1995-99, 1996-2000 and 1997-2001was 665.2, 628.4 and 560.1 mm respectively it increases towards east. About 77 per cent of annual rainfall in the district is received during the monsoon months. The normal annual rainfall in Gurgaon district is about 596 mm spread over 28 days. The south west monsoon sets in the last week of June and withdraws towards the end of September and contributes about 85% of the annual rainfall. July and August are the wettest months.15% of the annual rainfall occurs during the non-monsoon months in the wake of thunder storms and western disturbances.

70. Owing to its sub-tropical continental monsoon climate with hot summers and cold winters, Manesar experiences large variations in temperature across the year. May and June experiences high temperatures and the lowest is recorded in the months of December and January.

4. Air Quality

71. The air is generally dry during the summer season when the humidity is of the order of 40 percent in the morning and 20 percent in the afternoon. Humidity is high during the monsoon season, about 75 percent in the morning and 60 percent in the afternoon. During winter humidity is about 60 percent in the morning and 40 percent in the afternoon. Winds are generally light in the district during the summer and monsoon season. Winds blow generally from the sector South-West-West-North-West during morning and from the North-Western quardvant during afternoon throughout the year and during July and August they also blow from East and South-East. Haryana State Pollution Control Board (HSPCB) conducts ambient air quality monitoring in Manesar.

Noise levels were measured using integrated sound level meter manufactured by Quest Technologies. The integrating sound level meter is an integrating/ logging type with Octave filter attachment with frequency range of 31.5 to 16000 Hz. This instrument is capable of measuring the Sound Pressure Level (SPL), Leq and octave band frequency analysis. Noise level monitoring was carried out continuously for 24-hours with one hour interval starting at 0030 hrs to 0030 hrs next day. The noise levels were monitored on working days only. During each hour Leq were directly computed by the instrument based on the sound pressure levels. Lday (Ld), Lnight (Ln) and Ldn values were computed using corresponding hourly Leq. Monitoring was carried out at ‘A’ response and fast mode and was found to be within the prescribed limits. The result of the noise monitoring is shown in the table below:

5. Surface Water

73. Haryana State forms a divide between the Ganga and Indus water catchments. There are four irrigation systems in the State namely Western Yamuna Canal, Bhakra Canal, Agra Canal and Ghaggar Canal. In district Rewari, Jawahar Lal Nehru Canal is the main source of water. More than 98% area of the state is covered by the alluvial plain including Western Desertic Terrain of sand dunes. The state is bounded by Siwalik hills in the North, River Yamuna in the East and Aravalli hills in the South. Rivers Yamuna and Ghaggar flood plains constitute a large part of the State. The State has a climate that is arid to semi-arid. Annual rainfall averages 545 mm, ranging from more than 1000 mm in the extreme North-East to less than 300 mm in the Arid West. Surface water comes from the Sutlej via the Bhakra canal system and from the Yamuna via the Western Yamuna Canal system (Hellegers, 2007). The altitude in the state varies from 700 to 3600 ft (200 m to 1200 m) above mean sea level. 74. Development of water for irrigation can be cited as one of the major contributor to Haryana’s agricultural success. Western Yamuna Canal (WYC) with majority of its command area falling in Haryana and a liberal use of ground water can be considered to be the most significant influences on the agricultural turn-around in the State of Haryana. River Yamuna after traversing a distance of around 178 km in the hills enters, after cutting through the Siwalik range of lower Himalayas, the plains of Haryana at a place called Tajewala. It was here that the Emperor Firoz Shah Tughlaq constructed the Western (Jamuna) Yamuna Canal in 1355AD by converting one creek of the river into a canal to direct water to his hunting grounds in Hansi-Safidon area in what is now the state of Haryana. After his death the canal fell into disuse to be revived again in 1568 by Emperor Akbar. Emperor Shahjahan further improved the canal in 1628 as a ‘Shahi’ (royal) canal. The British re-modeled the canal during 1870-1882 when the famous barrage on river Yamuna at Tajewala was built and both Eastern Yamuna Canal (EYC) and the Western Yamuna Canal (WYC) were formalized as irrigation channels. 75. Later in 1990’s after the Yamuna water sharing agreement (Annexure 1) had been signed on May 12, 1994 between the Riparian States (Himachal Pradesh, Uttar Pradesh, Haryana, Delhi and Rajasthan) that the ageing Tajewala barrage was planned to be replaced by a new barrage, 3 km upstream, at a place called as Hathni Kund. The Hathni Kund Barrage (HKB, Fig 1) constructed with the assistance of World Bank (IDA credit 2592-IN) was completed in June 1999 but was commissioned only in 2002 (WAPCOS, 2003). The HKB enabled WYC to draw an additional supply of 4000 cusec from the river over and above its existing capacity of 16000 cusecs in the monsoon period (HID, 2007).

76. The Western Yamuna Canal (WYC) command area is located between the North latitudes 28°20’ and 30 29’ and East longitudes 75°48’ and 77°35’ and comprises the Eastern, Central and Southern parts of the State of Haryana. It has a Geographical area of about 13,543 sq km (CGWB, http://cgwb.gov.in/groundwater/conjunctive_use.htm) spread over 49 blocks in the districts of Karnal, Manesar, Sonepat, Rohtak and Jhajjar and partly in the districts of Hisar, Bhiwani, Jind, Yamunnagar, Gurgaon and Rewari. The total length of the WYC with all its branches is 325 km. In addition about 32 distributaries and 95 minors make up its combined length of 1,220 km. Further to prevent seepage losses along the WYC and to augment its supply, a lined canal over 69 km called as the ‘Augmentation Canal’ has been constructed in 2000. It takes off from Yamuna Nagar and out falls in WYC u/s of the Munak head (Major Water Resources Development Projects in Ganga basin http://www.nih.ernet.in/nih_rbis/india_information/Ganga_projects.htm). 77. Resultantly in 2007 it was decided to augment the capacity of GWS canal to 200 cusec and construct the new NCR Channel with a discharge of 500 cusec with a margin of free board in structure to augment it further by 200 cusec in future when the demand as planned above develops. The irrigation department of Haryana has constructed a new channel called the NCR Water Supply Channel for a planned discharge of 800 cusec at RD 223300 R (right) of Delhi branch, u/s of Kakroi Head. The Gurgaon Water Supply Channel (discharge at the Kakroi Head on WYC system) was first constructed by the Irrigation Department for HUDA (Haryana Urban Development Authority) in 1993-94 with a discharge of 135 cusec to supply drinking water to the towns of Gurgaon (100 cusec) and Bahadurgarh (35 cusec). 78. As presented in the following Table 10, channel water quality is good, but however does not conform to IS: 10500 – 1991 (Reaff. 1993, Ed. 2.2) and cannot be considered fit for drinking. Hence requires treatment (filtration and disinfection) before using it for drinking. As per the “Designated best use classification of Inland surface water” (National River Conservation Directorate, Ministry of Environment & Forest, Government of India) the canal water which is proposed source belongs to “Class-C” - Drinking water source with conventional treatment followed by disinfection. After treatment the water for drinking purpose has to meet the “Indian Standard- Drinking Water Specification (IS 10500: 1991)”. The report indicates that the treated water is meeting this requirement.

6. Groundwater

79. Large parts of the Haryana plains constitute a widely spaced topographic depression between the Siwalik hill and the Aravali hills which has created the typical internal drainage conditions. Resultantly, while there is a falling ground water table zone in Eastern and Southern parts (Yamuna Nagar, Karnal, Manesar, Sonepat (part), Faridabad and Gurgaon districts) of the State there is a rising water table zone, leading to soil Stalinization and degradation, in the Central and Western parts (Rohtak, Jhajjar, Jind, Bhiwani, Hisar, Sirsa and part of Sonepat districts). The State can thus be broadly divided into two distinct zones. The rising water table zone (52% of the State) and the falling water table zone (Eastern and Southern parts).

25

80. The water supply to the Gurgaon district is mainly based on groundwater through tube wells. 100% of the urban population is covered under drinking water supply scheme. The water supply to the villages is met out with the installation of hand pumps by the villager as spot and convenient source of water. The shallow tube wells for irrigation purpose in the district range from 45 to 70m deep, tapping the aquifer from 31m to 50m with a discharge of 400 to 1000lpm. Most of the shallow tube wells are either run by diesel engines or electric motors. The major part of the district is being irrigated through groundwater. A recent estimate, calculated by the Centre for Science and Environment, holds that Gurgaon's water table is declining at an average rate of 1.12 metre every year. 81. The shallow ground water of the district is alkaline in nature (pH 7.25 to 8.13) and is moderately to highly saline. According to permissible limits of Bureau of Indian Standards (BIS), groundwater is mostly unsuitable for drinking purposes in 88% of wells mainly due to high nitrate and fluoride contents that exceed the maximum permissible limits of these parameters which are 45mg/l and 1.5mg/l respectively. Decline of groundwater and salinity is a major problem in the district. Groundwater is declining at a rate with the range of 0.77m/yr (Bilaspur) to 1.2m/yr (Haily Mandi). All the blocks in district are over exploited. 82. Presently in Manesar GWS and groundwater is the prime source of water supply for most of the small and medium scale industries. The ground water quality in the project area is observed to having total alkalinity up to 235 which is slightly higher than desirable limit of 200 mg/L. Total dissolved solids in the ground water is 988 mg/L which is higher than the prescribed limit of 500 mg/L. The detailed groundwater quality monitoring results are presented in following table:

B. Ecological Resources 83. Forestry activities in the State are dispersed over rugged Shiwalik hill in North, Aravalli hill in South, Sand dunes in West and wastelands, saline-alkaline lands and waterlogged sites in the Central part of the State. Haryana is primarily an Agriculture State with almost 80% of its land under cultivation. The Geographical area of the State is 44212 sq. km which is 1.3% of India’s geographical area. It is not bestowed with bounty of Natural Forests and only 3.53% of its geographical area is under notified forests. As per India State of Forest Report, FSI, 2011, the Forest Cover in the State is 1608 sq.km which is 3.64% of the State's geographical area and the Tree Cover in the State is 1395 sq. km which is 3.16% of the geographical area. Thus the forest and Tree Cover of the State is 6.80% of its geographical area. The Haryana Sub-Region of NCR has 3.94% area (529.41 Sq. Kms.) under forest which is higher than the Haryana State average (3.5%). Gurgaon district has the highest forest cover in terms of percentage as well in the Haryana sub-region, which has successively grown from 7% in 2001 to 8.4% in 2011. 84. To promote sustainable development of Forest resources in the State, the Haryana Government has framed its Forest Policy in 2006. The policy has fixed the goal of achieving 20% Forest and Tree Cover in the State in a phased manner. This goal can be achieved by adopting Agro-forestry practices. Forest Department is also using genetically superior seedlings under Agro-Forestry on farm lands to increase productivity. 85. The subproject components are located in the built-up area of Manesar. Situated in south of Haryana State, Manesar is part of vast upland plain region, and is part of Yamuna River basin. Topography is plain and almost flat. There are no water bodies within the town. Roads with in the centre of the town are narrow, and congested with traffic, activities and pedestrians. Roads in outer areas are relatively wider. Due to flat topography and poor drainage facilities, water logging in some areas is common during rains. There are no protected areas, wetlands, mangroves, or estuaries in or near the subproject location. There are no forest areas. There are trees (local species) along the roads, and there is no need to cut for the construction drains by slightly changing the alignment of drains. There are no historically-, culturally-, archaeologically- or architecturally-significant or tourists areas in the town or near the project

87. National Capital Region Planning (NCRPB) has taken up the revision of the Regional Plan-2021 to promote growth and balanced development of the NCR. One of the important inputs for regional plan revision/preparation is the Land Use of 2012 and change analysis (1999-2012). NRSC (National Remote Sensing Centre) has prepared the NCR regional land use from Resourcesat-2 LISS-IV data pertaining to 2012 and change analysis in Geospatial environment. During the period 1999-2012, built-up area has increased by 2.81% from 8.1% to 10.91%. Further NRSC has extended geospatial support to NCRPB for revision of Regional Plan 2021. The revised NCR Regional Plan–2021 has been approved by the Board in the 34th meeting of the Board held on 20th January 2014. The regional plan shows the development areas/green belt area and balanced development of NCR. As per the revised maps, the proposed site not falling under the NCZ area.

2. Industry & Agriculture

88. Haryana is one of the most economically developed and industrialized States of India. The Gross State Domestic Product is Rs.245,586 crores in 2010-11 at current prices. The average per capita income in State at constant prices is Rs.44,493 (1999- 2000 base year) and Rs.77,878 (2009-2010). The Sub-Region had shown a consistent increase in both its GSDP and Per Capita Income from 2004-05 to 2009-10. Gurgaon recorded the highest GDP (229,208) in the sub-region in the year 2009-10 followed by Faridabad district (i.e., 106,896). Gurgaon has evolved in the last two decades from a stretch of agricultural land in the neighboring State of Haryana to a flourishing suburb of Delhi, catering to the ever growing requirements of the National Capital Region (NCR) of Delhi. Only some parts of the North and North–West regions remain agricultural while most of the other sectors, in their entirety, have evolved as residential sectors interspersed with commercial areas and industrial areas along the main transportation line of NH-8 (National Highway-8) that connects Delhi to Mumbai. The entrepreneur of Delhi discovered Gurgaon as a separate nucleus offering a combination of various inputs of land, material, labor, skill and transport. 89. The Sub-region is a part of the Indo-Gangetic Plain. There are mainly 2 cropping seasons, Rabi and Kharif. Majority of the area in the region is utilized during the Rabi and Kharif (double crop) seasons due to better irrigation facilities. Major Kharif crops include Rice, Jowar, Bajra, Gaur, Maize, Cotton, Sugarcane, Groundnut and Pulses. Rabi crops include Wheat, Barley, Gram, Rapeseed/Mustard and Pulses. The short period available in between Mid-May and July is sometimes also used for raising a third crop particularly in the areas where assured irrigation is available for watering the crop during the dry season. Northern portion of the region is characterized by good agricultural area due to fertile alluvial soils, marginal to good quality of groundwater, network of irrigation, canals, and tube wells and relatively better natural drainage. On the contrary, Gurgaon due to lack of rainfall, poor irrigation facilities, poor groundwater quality coupled with desert terrain with sand dunes, have relatively less cultivation during Kharif season. Beside agriculture, animal husbandry and fishery also play a subsidiary role in the economy of the district. 90. Manesar is a fast growing industrial town in Gurgaon district of the State of Haryana in India, and is a part of the National Capital Region (NCR) of Delhi. Integrated Manesar Township is a 1,750-acre (7.1 km) Ultra Modern Integrated Industrial Park. Manesar has been developed in four phases. HSIDC has developed 1,750 acres (7.1 km) of land in Phase-I, while work is in progress in Phase-II (180 acres) and Phase-IV (650 acres). HSIDC has allotted Phase-III (600 acres) to Maruti Udyog Limited for their expansion project. 91. Major units in the industrial estate of Manesar are Maruti Suzuki Ltd., Honda Motorcycle and Scooter India Ltd., Johnson Matthey, Suzuki Powertrain India Ltd., Hero Motors Ltd., Crew BOS India Ltd., Nagata India, Mitsubishi Electric Automotive India Ltd., Baxter India Pvt. Ltd., Maxop Engineering, Amtek Saccardi India Ltd., Lumax Automotive Systems Ltd., Mehsana Distt. Milk Producers Union Ltd. (Amul), Mankind Pharma Ltd., Sudhir Gensets Ltd., etc

3. Infrastructure

92. Water Supply and Sewerage. Water supply and sewerage system is provided by HUDA in the area developed by them, by HSIIDC in the IMT Manesar area and by PHED in Manesar village. These agencies provide all the basic services pertaining to water supply and sewerage facilities. PHED/PWD-WSSD is a line department responsible for providing water supply and sewerage services in Haryana. HUDA is an autonomous government body and

29

functions as the land developer in the state. HUDA is responsible for providing services only to the areas developed by it, which are called as HUDA “Sectors”. 93. Groundwater is the one of the source of water supply in IMT Manesar. Groundwater is extracted through 45 tube wells drilled in various parts of the area. About 15 MLD of water is supplied daily from these tube wells. The other source is GWS Channel which supplies about 20 MLD of water. Number of water connections is 478 domestic and 1863 industrial connections at present. In group houses one connection has been provided for each group house which may consist on an average basis of about 50 households. 94. Underground sewerage system in IMT Manesar has been developed by HSIIDC such as to cover all plots. Sewage treatment plant of 15 MLD capacity is existing and its capacity is being enhanced to 55 MLD by way of constructing additional plant & improving existing STP. The effluent is disposed through effluent channel which finally leads to Badshahpur drain. 95. Storm Water Drainage. Open drainage system is provided in the IMT Manesar to cater for collection and conveyance of storm water during rains. This open drain network consisting of road side drains is connected at several places to Manesar Main Drain running across the town.

4. Transportation

96. Manesar is 32 km from IGI Airport and is just 16-23 km from Gurgaon and has some of the best urban infrastructure in Northern India. Located on National Highway 8, is served by local buses plying on this route. The area is well connected with Delhi, Rewari, Dharuhera, Jaipur, Ahmedabad and Mumbai. Air connectivity is at IGI Airport. The nearest railway station is Ghari Harsaru (GHH) and renowned station is Gurgaon. 97. During 2010-11, total length of metallic roads in the district is 717 km. All villages in district are well connected with metallic roads; thus indicating 100% road connectivity for villages. The district has 10 railway stations namely Gurgaon, Sultanpur, Garhi Harsaru, Inchhapuri, Patuadi Road, Patli, Taj Nagar, Basai Dhankot Railway Station, etc. and the total length of railway line in the district is 55 kms. Also the gauge railway line between Farukh Nagar and Garhi Harsaru has been converted to broad gauge railway line. Gurgaon city is also well connected to National Capital Region by metro train services. Manesar is provided with a relatively good road network, particularly in the model town area, where streets are wide. 98. There are regular bus services to its hinterland and other towns and cities in the neighboring States operated by both by State-run and private transport services. Within the Manesar, commuters mainly depend on IPT modes of Auto Rickhwas and Cycle Rishwas, besides the private vehicles for intra-city travel. D. Social and Cultural Resources

1. Demography

99. The Gurgaon district has seen growth of 73.93% in population from 2001 to 2011 while the same from 1991 to 2001 was 44.64%. The growth in rural population from 2001 to 2011 is 15.82% while that in urban population is 236.45%. The population density of the district in 2011-12 is 749 per sq.km which was 626 per sq. km in 2001-02. In Manesar thensil total population is 116,603, out of which the rural population is 93,148 and the urban population is 23,455.

The official languages used are Hindi and English.

2. History Culture and Tourism

102. Gurgaon has a rich historical background and has been in existence since the times of Mahabharata. According to Indian epic, the Mahabharata, Gurgaon was a thick forest in which the ashram of Guru Dronacharya existed. It was here that Pandav and Kourav princes got their training in warfare. Because of Guru Dronacharya's ashram, people started calling it the 'Gurugram' which later on changed into 'Gurgaon'. This place had been gifted to Guru Dronacharya by Yudhister, as 'Guru-Dakshina'. Manesar is aTehsil in the district of Gurgaon. 103. The common festivals celebrated in the district are Holi, Janamashtami, Dussehra, Diwali, Shivaratri, etc. Mela Masani Mata or Sitla Mata ka mela and mela Chhat Bhadon or Baldev Chhat are some of the important fairs held in Gurgaon district. Apart from these, Gurgaon city also witness huge gathering and celebration during Christmas period and New Year. With rapid urbanization, and due to its close proximity to Delhi, the cultural aspects are now taking a more modern turn. There is a natural “Damdama Lake” and Bird Sanctuary (Sultanpur) in the district.

V. ENVIRONMENTAL IMPACTS & MITIGATION MEASURES

A. Overview 104. As a general practice, an IEE should evaluate impacts due to the location, design, construction and operation of the project. Construction and operation are the two activities in which the project interacts physically with the environment, so they are the two activities during which the environmental impacts occur. In assessing the effects of these processes therefore, all potential impacts of the project should be identified, and mitigation is devised for any negative impacts. Following sections evaluate impacts of the proposed rehabilitation and augmentation of water supply system in Manesar. B. Construction Impacts 105. Proposed water supply subproject involves the following:

i. Construction of intake in NCR channel at Budhera & construction of raw water RCC box channel from Budhera to Basai

ii. Construction of raw water storage, pumping station, pumps at Basai iii. Raw water pumping main 900 mm DI Basai to Harsaru iv. Raw water storage of 7 days capacity, raw water pumping to WTP

31

v. Construction of WTP 45 MLD Capacity, Clear water storage tank of 2 hour detention time, Clear water pumping station with pumps and generator at Harsaru

vi. Clear water pumping main 10500 m DI 800 mm dia Harsaru to sector 7 & 3 Manesar

vii. Rehabilitation of existing canal based water supply system from Basai to Manesar

1. Construction Method

106. The intake at Budhera and RCC box channel from Budhera to Basai will be constructed by the irrigation department as they are the expert agency for such works and also the GWS channel and NCR channel belongs to them. The intake will be constructed on the embankment of channel. RCC box channel from Budhera to Basai will be constructed along GWS channel & with in the available land of the channel. 107. Raw water storage tanks for 2 hour detention time and raw water pumping will be done at Basai & all related structures will be in existing Basai head works. 108. All pipe lines from Basai to Harsaru and Harsaru to Sector 7 & 3 will be along the roads and Raw water reservoirs, WTP, Clear water reservoir and clear water pumping station etc. will be located in Harsaru existing head works. 109. Canal intake will be developed by creating an opening in the existing canal, and installing a discharge gate. As the canal is owned and maintained by Irrigation Department of Government of Haryana, as per the procedure it will be constructed/installed by Irrigation Department and the cost will be borne by the HSIIDC. Work will be carried out as per the standard construction practices of Irrigation Department. Construction will be undertaken by isolating the construction area by constructing a coffer dam into one side of the canal, while the water can flow uninterrupted through the remaining section. This practice will avoid the closure of canal. Construction work will be completed in about a week. 110. RCC box channel 6 m wide & depth 1.02 m+0.6 m (Free Board) will be constructed from the Budhera to Basai. Design and construction will be such that the water from canal will flow by gravity into the channel. A trench of size 7,000 mm wide and 2000 mm deep will be created in ground using backhoe digger, and the base will be leveled and a Plain Cement Concrete bed of 150 mm thickness will be provided. Reinforcement bars will be arranged over the bed and in the wooden case for walls, and the concrete, mixed on the site using the mixers, will be poured into to form bed and walls of the channel. Subsequently, bottom and inside walls will be smoothened by applying cement mortar by hand. 111. Raw water reservoirs will be constructed at Basai and Harsaru by excavation. Two rectangular underground sumps (raw and clear water) will be constructed in the premises. Construction would involve creation of large cavity using back hoe diggers. Reinforcing rods would be placed in wooden casing and the concrete will be poured into to form bottom, walls and top of the sump. Necessary opening on the top of the sumps will be left for operational purposes. 112. WTP, Raw and Clear Water Pump Houses (RWPH and CWPH) will be constructed at Harsaru. This will involve construction of a room with brick masonry walls and RCC roof slab. Pumps, brought to the site on a truck, will be installed using cranes or manually. Water

32

Treatment Plant will involve construction of following components.

113. The raw water pumping (ring main) and clear water pumping main will be buried in trenches adjacent to roads, in the un-used area within the ROW, at the edge of the road carriage way. However the distribution mains will be located in roads and streets in the town, where in some places this area is occupied by drains or the edges of shops and houses etc, so to avoid damage to property some trenches may be dug into the edge of the road. 114. Trenches will be dug using a backhoe digger, supplemented by manual digging where necessary. Excavated soil will be placed alongside, and the pipes (brought to site on trucks and stored on unused land nearby) will be placed in the trench by using crane for larger diameter pipes. Pipes will be joined by mechanism, after which excavated soil will then be replaced manually on beneath, sides and top of the pipe and compacted by a vibrating compressor. Where trenches are dug into an existing roadway, the bitumen or concrete surface will be broken by hand-held pneumatic drills, after which the trench will be excavated by backhoe, and the appropriate surface will be reapplied on completion. 115. Pipes are normally covered by 1.2 m of soil, and a clearance of 150 mm is left between the pipe and each side of the trench to allow backfilling. The maximum and minimum trench sizes for pumping main will be 2 m deep and 1.2 m wide (for 900 mm dia pipe) and 1.5 m deep 0.6 m wide (300 mm dia pipe).

2. Impacts on Physical Resources

a. Generation of surplus soil and its disposal 116. The HSIIDC has proposed a water supply scheme from Budhera NCR Channel to IMT Manesar. Budhera is dead end of NCR Channel. RCC box channel will be constructed for ultimate requirement from Budhera to Basai. From Basai the pipeline will be laid on the right bank of the effluent drain pipeline of the ETP till Harsaru. In Hasaru the water will be treated in water treatment plant and clear water will be pumped to IMT Manesar. There is one railway

33

crossing in the stretch for which the necessary permissions will be obtained. The proposed waterworks campus comprising of raw water Sedimentation & Settlement tanks, WTP, clear water reservoirs with pumping stations, will be developed on a selected site at Harsaru. Works require excavation for underground sumps and foundations for the water treatment plant. Excavation for the raw water Sedimentation & Settlement tanks is expected to generate about 10,65,853.0 m3 of soil. 117. Water pumping main work will involve excavation, the impacts are less significant. It is estimated that the trench excavation for water supply lines will generate around 1,14,782 m3 of soil. After construction, a part of the trench will be occupied by the pipe and in the remaining portion excavated soil will be backfilled on beneath, top and sides of the pipes. This means that most of the soil will be retained for refilling the trench, and an estimated about 78912 m3 of waste material will be left over. The topography of the area is almost flat, and there are many areas which face problem in draining the rain water due to lack of slope. Due to comparatively high road level than the adjacent areas, especially in newly developing areas, water accumulation is common during rains. Raising the ground-level during the construction is very common, and therefore the demand for soil high. Surplus soil shall be utilized for the following beneficial activities in order priority:

Utilize for raising the ground-level of Harsaru & Basai

Utilize in other construction activities implemented by Government departments within Manesar/Gurgaon

Provide waste soil to local people for filling up low laying areas. 118. The total earthwork in excavation including for pipe line and Basai works will be in the quantum of 14,87,647.20 m3. There will therefore be quite large physical changes at the construction sites, and this quantity of excavated earth cannot be dumped without causing further physical impacts (on air quality, topography, soil quality, etc) at the point of disposal. However, this could be avoided by utilization of soil for any beneficial purposes. This quantity of soil will be utilized beneficially for raising the level of the campus, avoiding the need for disposal elsewhere. The campus area at Harsaru is 100 acres and at Basai it is 6.5 acres. Thus this large area will accommodate the surplus excavated earth.

b. Interference with surface drains and groundwater table 119. The other physical impact commonly associated with large-scale excavation (effects on surface and groundwater drainage) should again be minimal by the fact that this work will be conducted in the dry season. As the depth of water table is deep (about 45 - 70 m) the trench excavation may not interfere with the groundwater drainage. Rainfall in Manesar is limited and concentrated during the monsoon months of July-September. During the rains, there is possibility of water accumulation in open trenches excavated for pipelines. The contractor therefore shall implement the following:

Avoid scheduling of excavation work during the monsoon months

Complete pipe laying work in excavated stretches and refill before onset of monsoon

In unavoidable circumstances, protect open trenches from entry of rain water by raising earthen bunds with excavated soil and ensure that drains are not blocked with excavated soil

34

c. Dust and noise generation from excavation & construction works 120. The work will almost certainly be conducted in the dry season, so there is also a lot of potential for the creation of dust, from the excavation of dry soil and its storage, and leveling on the ground. Action will therefore be needed to reduce physical impacts at both the construction and disposal sites, by controlling dust and reducing the amount of material to be dumped. The Contractor should therefore be required to:

Cover or damp down by water spray on the excavated mounds of soil to control dust generation;

Apply water prior to levelling or any other earth moving activity to keep the soil moist throughout the process;

Bring the material (aggregate) as and when required;

Ensure speedy completion of work – trench excavation, laying of sewer and refilling, to remove surplus soil as soon as possible;

Use tarpaulins to cover loose material that is transported to and from the site by truck.

In case of surplus soil is provided for other departments or private persons, it will be the responsibility of contractor to ensure that it proper handling, transport & utilization

Use tarpaulins to cover loose material/soil that is transported to and from the site by truck

Control dust generation while unloading the loose material (particularly aggregate) at the site by sprinkling water and unloading inside the barricaded area

Clean wheels and undercarriage of haul trucks prior to leaving construction site

Stabilize surface soils where loaders, support equipment and vehicles will operate by using water and maintain surface soils in a stabilized condition where loaders, support equipment and vehicles will operate

Don't allow access in the work area except workers to limit soil disturbance and prevent access by fencing

121. Activities like cutting/breaking open of road surface will certainly generate noise and vibrations. The following measures therefore shall be implemented to reduce the impact:

Provide prior information to the local public about the work schedule

Do not conduct noise generating activities in the night

Ensure that there are no old and sensitive buildings that may come under risk due to the use of pneumatic drills

Employ manual methods, where required

d. Loss of fertile top soil 122. The waterworks campus will be developed on a 100 acres land, which is a SEZ land with no agricultural activity (fenced area). Hence loss of precious fertile top soil is negligible. However, The top soil of about 1 ft depth (0.3 m) may removed and preserved separately for use within the site for plantations and the surplus soil may be given to surrounding farmers.

35

e. Mining for construction materials 123. Large quantities of construction material like sand and aggregate will be required for WTP and reservoir constructions. As the excavated soil will be used for refilling trenches, pipeline construction will require minor quantities. Normally materials are procured from Gurgaon District. To avoid any impacts related to mining of material, the contractor will be required to obtain sand and other mining material required for construction only from quarries licensed by the Directorate of Geology and Mining, Government of Haryana.

3. Impact on Ecological Resources

124. There are no significant ecological resources in the town (protected areas or rare or important species or habitats), so the construction should have no ecological impacts. Tree cover in the town is very limited. Roadside trees should not be removed unnecessarily to lay pipelines, and to mitigate any such losses the Contractor should be required to plant and maintain two trees (of the same species) for each one that is removed.

4. Impact on Economic Development

a. Land acquisition & resettlement 125. The WTP works will be constructed over a HSIIDCs 90 acres of land available at Harsaru to accommodate storage and sedimentation tanks for 7 days storage, 6.5 acre land is available at Basai & strip (15 m wide) of land is available from Basai water works to Harsaru & onwards up to sector 7, laid to raw water pumping from Basai to Harsaru & WTP at Harsaru. The site is located ideally adjacent to the canal for development of canal based waterworks. 126. There is no LA involved in this sub-project, hence issues related to Involuntary Resettlement is not addressed in this report. 127. Pipeline will be laid in the ROW of existing roads (either adjacent to the road, or beneath the road surface in narrower streets). There should thus be no need to acquire land from private owners, so there should be no direct effect on the income or assets of landowners, or the livelihoods of tenants.

b. Impeded access and loss of business 128. During the laying of pumping main and distribution lines, particularly in narrow streets and streets with on street commercial activities, there may be temporary disruption or relocation of hawkers and vendors. 129. Implementation of the following best construction measures will reduce the inconvenience and disturbance to the public:

Informing all residents and businesses about the nature and duration of any work well in advance so that they can make necessary preparations;

Requiring contractors employed to conduct these works to provide wooden planks across trenches for pedestrians and metal sheets where vehicle access is required;

Increasing workforce to complete the work in a minimum possible time.

36

c. Disruption to other infrastructure services

130. During the laying of water supply lines along the roads, various infrastructure services may be affected. It is therefore required to implement following measures to avoid or minimize the impact during construction:

Identify the services to be affected in each zone and notify the respective agencies (Electricity, Telephone, etc.) about the construction work and if there is any need for shifting

Coordinate with respective agencies and provide prior information to public about the disruption in services during construction; this can be announced via mass communication systems like local/vernacular newspapers.

Provide alternative arrangement for disrupted services

During construction, the water supply service will be affected. In case of water supply being affected for more than a day, alternative water supply may be provided through mobile tankers.

131. Transport is another type of infrastructure that will be affected by the pipeline laying work. In this sub-project activity, there is no construction along the road, at the road crossings culvert will be provided and during the construction of the culverts the option of traffic diversion will be there with proper signages and the same will be intimidated to the villagers for their convenience. There is one railway crossing exists in the stretch for which the necessary permissions will be obtained. Following measures can potentially avoid traffic disruptions:

Conduct work during light traffic; explore night working schedule ensuring workers and public safety

Plan work such that trench excavation, pipe laying and refilling including compacting, at a stretch is completed in a minimum possible time

Provide for immediate consolidation of backfilling material to desired compaction to avoid future settlement risk - this will allow immediate road restoration and therefore will minimise disturbance to the traffic movement

Do not close the road completely, ensure that work is conducted onto edge of the road; allow traffic to move on one line. In unavoidable circumstances of road closure, provide alternative routes, and ensure that public is informed about such traffic diversions

At all work sites public information/caution boards shall be provided - information shall inter-alia include: project name, cost and schedule; executing agency and contractor details; nature and schedule of work at that road/locality; traffic diversion details, if any; entry restriction information; competent official’s name and contact for public complaints.

132. It is inevitable that there will be an increase in the number of heavy vehicles in the town (particularly trucks carrying construction materials and removing waste) and this could disrupt traffic and other activities. These impacts will therefore need to be mitigated by:

Careful planning of transportation (material and waste) routes in coordination with the Traffic Police to avoid sensitive areas as far as possible, including narrow streets, congested roads, and other important area

Scheduling the transportation of waste to avoid peak traffic periods

37

133. There should be no effects on other features with economic implications (such as infrastructure, industry and commerce) and should also be no effects on traffic or transport, as all of the other works will be conducted on small parcels of Government land.

5. Impact on Social and Cultural Resources

a. Damage/disturbance to historical sites 134. There are no protected historical monuments in Manesar within the subproject area. So there is no risk that any work involving ground disturbance could uncover and damage archaeological and historical remains. Excavations for laying of pipelines within 300 m of sites requires permission from ASI. However, it will be necessary to adopt a series of measures, to both avoid sensitive sites and recognize and protect any chance discoveries. These include:

Obtain permission from ASI for laying of pipelines within 300m of sites.

Ensure that any chance finds are recognized and measures are taken to ensure they are protected and conserved.

If any chance finds are recognized, the Contractor should: o Stop work immediately to allow further investigation if any finds are

suspected; o Inform PWD - WSSD; call in the ASI if a find is suspected, and taking any

action they require to ensure its removal or protection in situ.

135. The water pipeline work likely to disturb some modern-day social and cultural resources, such as schools, hospitals, temples etc. Impacts will include noise, dust, and interrupted access for pedestrians and vehicles. Mitigation will therefore be needed to protect these resources and to enable usage by local people and visitors to continue throughout the construction work. This will be achieved through several of the measures recommended earlier, including:

Avoiding working at sensitive times,

Limiting dust by removing waste soil quickly, bringing sand to site only when necessary, covering and watering stockpiles, and covering soil and sand when carried on trucks;

Increasing the workforce in sensitive areas to complete the work quickly;

Providing wooden bridges for pedestrians and metal sheets for vehicles to allow access across open trenches where required (including access to houses);

Using modern vehicles and machinery with standard adaptations to reduce noise and exhaust emissions, and ensuring they are maintained to manufacturers’ specifications.

b. Public & worker safety

136. There is invariably a safety risk when substantial construction such as this is conducted in an urban area, and precautions will thus be needed to ensure the safety of both workers and citizens. The Contractor will be required to formulate and implement health and safety measures at construction sites, which should include such measures as:

Following standard and safe procedures for all activities – such as provision of shoring in trenches where required in deeper trenches of more than 2 m

38

Consulting the town authorities to identify any buildings at risk from vibration damage and avoiding any use of pneumatic drills for cutting roads;

Excluding the public from the site – enclosing the construction area, warning boards and sign boards

Ensuring that all workers are provided with and use appropriate Personal Protective Equipment (helmet, hand gloves, boots, masks etc);

Maintaining accidents reports and records 137. There is a risk of contact with carcinogenic material when working with AC pipes. Under the subproject, it is designed that where there is a need to replace the existing pipes, the AC pipes will left as it is in the ground and the new pipes will be laid adjacent. There are no new AC pipes proposed.

c. Economic benefit 138. There could again be some short-term socio-economic benefits from the construction work if local people gain employment in the workforce. To ensure that these benefits are directed to local people, the Contractor should be required to employ as much of his labour force as possible from the local communities in the vicinity of construction sites. Drawing of majority of workforce from local communities will avoid problems that can occur if workers are imported, including social conflicts and issues of health and sanitation due to labour camps. If temporary labour camps are to be provided; Contractor should ensure that they are maintained well with proper water supply and sanitation facilities. C. Operation & Maintenance Impacts 139. Regular operation of water supply system involves water abstraction, water treatment including chlorine injection into water supplies, pumping and water distribution to consumers.

140. With the proposed canal based water supply system, the existing groundwater based system will be discontinued in future. In Sub Phase-I, the water supply will increase from existing 35 MLD to 95 MLD. Details are as follows:

Table 14: Sub Phase-I water supply details

Source Existing Proposed

Canal Water 20 MLD 35 MLD

Tube Well 15 MLD 15 MLD

New Canal System - 45 MLD

Total 35 MLD 95 MLD

1. Impacts on Physical Resources

141. One of the main risks of the water supply system improvement through increased quantity is that the source will be used unsustainably, at may be at a rate that is above the available quantity and that the source becomes depleted as a result. Here the water will be sourced from West Jamuna Canal (WJC) system through NCR Channel. The total extraction will be about 6.5% (80/1223) of total flow in NCR Channel, and this will be within the limits of water allocated3 to HSIIDC in the NCR Channel. Therefore no impacts on source sustainability

3 Government of Haryana conceived NCR channel of 500 cusecs capacity in Phase-I to meet requirement of

Gurgaon-Manesar Urban complex. HSIIDC reserved 317 cusecs water in NCR channel and has shared cost of

39

envisaged. It should also be noted that water reuse measures envisaged in water demand calculations shall be implemented. 142. A main requirement for O & M will be regular operation of WTP which involves various processes: Clariflocculation, Rapid Sand Filtration and Chlorination, Clear Water Storage and Pumping Arrangements, etc. The backwash from the rapid sand filters is proposed to be brought back into the raw water storage tanks, thereby avoiding the problem of its disposal into surface water bodies or on land. Water will flow in gravity from the inlet chamber through all components of WTP and finally the treated water flows into the clear water sump in the premises. Chemicals such as Alum and chlorine will be used in the treatment processes. 143. Water treatment process will generate waste, which will comprise of the following: (i) sludge from sedimentation of particulate matter in raw water, flocculated and precipitated material resulting from chemical coagulation, residuals of excess chemical dosage, plankton etc; and waste from rinsing and back washing of filter media containing debris, chemical precipitates, straining of organic debris and plankton. 144. In the project design, it is proposed to provide recirculation system for filter wash water. For this purpose, wash water will be collected in two open tanks for alternative use, with a storage capacity of one day wash water in each tank. The settled water will be pumped back into the Inlet chamber and re-circulated with the raw water. Sludge from these tanks and also from the clarifier will be collected in a sludge tank. Sludge from the tanks will be sent to sludge drying beds, and the dried sludge will be sent either for land filling or used as soil conditioner. 145. Another main requirement for maintenance of the water supply infrastructure will be for the detection and repair of leaks. The usage of good quality new pipes should mean that pipeline breaks are very rare, and that leaks will be minimal. Leaks will be detected and rectified during operation phase. Repairs will be conducted in essentially the same way that the pipes were laid. Trenches will be dug to reveal the leaking area and the faulty connection will be re-fitted, or the pipe will be removed and replaced if necessary. 146. An important aspect of increased water supply is that of increased sewage generation, which needs to be treated and disposed properly without causing any impacts. With the current rate of water supply, without the project the gross water supply to the sub-project area is 25 MLD. With the project this will increase to 80 MLD. The sewage generation (70 percent of net water supply at consumer end) with the current situation will be 17.5 MLD, while with the project implementation same will increase to 56 MLD. The existing STP of 15 MLD and proposed STP which is under construction of 55 MLD (including existing) will take care of the waste water generated. Sewerage system has been laid in most of the sectors. Any left out work will be taken up under HSIIDCs own funding.

2. Impacts on Ecological Resources

147. The area proposed for WTP site is not a NCZ, but it was an SEZ land now handed over to HSIIDC for public water works as stated earlier. Even at present raw water reservoirs and raw water pumping station is in operation at the proposed WTP site. There is no conservation area,

channel in proportion to its requirement. HSIIDC vide letter IA:2010:251 dated 20-04-2010 informed the take-off points with quantity of water as follows: i. 110 cusecs of water at Badli at RD 52.400 KM, ii. 120 cusecs of water near village Mundakhera at RD 64.500

KM and iii. 120 cusecs of water at Budhera at RD 70.700 KM.

40

like a Nature Reserve, Sanctuary, National park or other area of Ecological importance close to proposed WTP site or around the town, any repairs or maintenance work and regular operation of WTP can be conducted without ecological impacts. The WTP design includes necessary facilities for safe disposal of back wash water (recirculation) and sludge (sludge drying beds), and therefore no impacts are anticipated. 148. A major ecological benefit of this project will be on groundwater regime. As presented in the baseline section, groundwater in and around Manesar is over exploited and in some areas the quality has become poor. This subproject is designed with surface water as source, eliminating the dependence on groundwater.

3. Impacts on Economic Development

149. Although network repairs could result in shops losing some business if the work means that access is difficult for customers, any losses will be small and short-lived and will probably be at the level of normal business fluctuations. Nevertheless, implementation of the following best construction measures will reduce the inconvenience and disturbance to the public:

Informing all residents and businesses about the nature and duration of any work well in advance so that they can make preparations if necessary;

Requiring contractors employed to conduct these works to provide wooden walkways across trenches for pedestrians and metal sheets where vehicle access is required;

Consulting the Traffic Police regarding any such work so that it can be planned to avoid traffic disruption as far as possible, and road diversions can be organised if necessary.

4. Impacts on Social and Cultural Resources

150. The operation & maintenance work will confine to within the facilities footprint, and no new areas will be disturbed or excavated. Therefore there are no likely impacts or risks. 151. The citizens of the town will be the major beneficiaries of the improved water supply, as they will be provided with a constant supply of better quality water, piped into their homes. This should improve the social capital of the city, and individual and community health and well-being. Diseases of poor sanitation, such as diarrhea and dysentery, should be reduced, so people should spend less on healthcare and lose fewer working days due to illness, so their economic status should also improve, as well as their overall health.

VI. INSTITUTIONAL ARRANGEMENTS

A. Institutional Arrangements 152. Following agencies will be involved in implementing this Water Supply Subproject in Manesar:

(i) NCRPB: National Capital Region Planning Board is the funding agency for the project.

(ii) Implementing Agency (IA): Implementing Agency of the Project will be HSIIDC. IA will be responsible for the project implementation. Operation & maintenance

41

will also be the responsibility of the IA. (iii) Design and Supervision Consultants: Implementing Agency will be assisted by

Design and Supervision Consultants (DSC) in tendering, and reviewing and revising designs during the construction, if required, and supervising the construction to ensure quality.

(iv) Construction Contractors: IA will appoint Construction Contractors (CC) to build the infrastructure elements.

153. Implementing the project according to and incompliance with the policies the funding agency, NCRPB, will be the responsibility of the Implementing Agency (IA). The Environmental and Social Management Cell (ESMC) of NCRPB will deal with environmental and social safeguard issues. ESMC would guide and monitor IA in complying with its ESMS and Policy. 154. ESMC - The ESMC will be housed inside the appraisal function of NCRPB and will have two distinct sub-functions, i.e. managing environmental safeguards and social safeguards. ESMC will be provided with one full-time staff - safeguards officer, who will look after the day-to-day activities related to the safeguard compliance. Safeguard Officer will be responsible for both environmental and social safeguard functions. Based on the necessity, the Safeguards Officer will source expertise from outside/external consultants on a case-to-case basis. ESMC will review and approve IEE, oversee disclosure and consultations, and will monitor the implementation of environmental monitoring plan and environmental management plan where required. The Construction Contractor (CC) will implement mitigation measures in construction. IA or DSC will monitor the implementation of mitigation measures by the CC. ESMC will oversee the implementation of EMP. Implementation of mitigation and monitoring measures during the Operation and Maintenance (O&M) stage will be the responsibility of the implementing agency.

VII. ENVIRONMENTAL MANAGEMENT PLAN

A. Environmental Management Plan 155. The proposed subproject and its components, the baseline environmental profile of the subproject area, the anticipated environmental impacts and appropriate mitigation measures to avoid/ reduce/ mitigate/compensate for the identified impacts have been discussed in detailed in earlier sections. 156. An Environmental Management Plan is developed for implementation listing the impacts, appropriate mitigation measures, delegating the responsibility of implementation to concerned agencies. This is shown in the following Table 15. 157. A program of monitoring will be conducted to ensure that all parties take the specified action to provide the required mitigation, to assess whether the action has adequately protected the environment, and to determine whether any additional measures may be necessary. Regular monitoring of implementation measures by construction contractors will be conducted by the Implementing Agency. Periodic monitoring and overseeing of implementation of mitigation measures will be conducted by the ESMC of NCRPB. Monitoring during operation stage will be conducted by the Operating Agency. 158. Most of the mitigation measures are fairly standard methods of minimizing disturbance from building in urban areas (maintaining access, planning work to minimize public inconvenience and traffic disruptions, finding uses for waste material, etc). Monitoring of such measures normally involves making observations in the course of site visits, although some

42

require more formal checking of records and other aspects. 159. Table 15 shows the proposed Environmental Monitoring Plan (EMP) for this Project, which specifies the various monitoring activities to be conducted during different phases of the project. The EMP describes: (i) mitigation measures, (ii) location, (iii) measurement method, (iv) frequency of monitoring and (v) responsibility (for both mitigation and monitoring).

B. Environmental Management and Monitoring Costs 160. Most of the mitigation measures require the Contractors to adopt good site practices, which are part of their normal procedures, so there are unlikely to be major costs associated with compliance. These costs of mitigation by the contractors are included in the budgets for the civil works. Mitigation and monitoring provided by the IA/EA or its DSC will be part of incremental administration costs, which are already included in the project. Additional costs required for environmental quality monitoring is indicated in the following Table 16.

VIII. GRIEVANCE REDRESS MECHANISM

161. As the work is being done along inhabited areas and areas with various human activities, and most of the impacts are construction-related, and therefore it is anticipated that improper or inadequate implementation of EMP may lead to disturbance and inconvenience to local people and traffic. In order to provide a direct channel to the affected persons for approaching project authorities and have their grievance recorded and redressed in an appropriate time frame, HSIIDC will establish a Grievance Redress Mechanism, which will be functioned throughout the construction period. 162. A Complaint receiving system will be put in place at the project office of HSIIDC in Project Area. A complaint register and complaint forms will be made available at the site office of each contractor, with a display board indicating availability of such facility. This will accept complaints regarding the environment safeguard issues in implementation of the project. The grievances received and actions taken will be included into the environmental monitoring reports submitted to NCRPB. 163. HSIIDC will constitute a three-member Grievance Redressal Committee (GRC) comprising of the Executive Engineer, HSIIDC (Jurisdictional EE), the elected member of the project area and one member from the public who is known to be persons of integrity, good judgment and commands respect among the community. The existence of the GRC will be disseminated to the villagers through printed handouts providing details of the structure and process in redressing grievances. Any aggrieved person (whose complaint to the complaint cell is not redressed to his/her satisfaction) can approach GRC, chaired by the Executive Engineer, HSIIDC and if the grievance is not addressed, the aggrieved person will be directed to approach the District Collector. The aggrieved person will have the right to approach the court of law, if he/she is still unsatisfied with the decisions taken by the GRC and the Collector.

64

164. The GRC will meet every month, determine the merit of each grievance, and resolve grievances within a month of receiving the complaint; failing which the grievance will be addressed by the District Collector. If not satisfied, the affected households will have the option of approaching the appropriate courts of law. Records will be kept of all grievances received including: contact details of complainant, date that the complaint was received, nature of grievance, agreed corrective actions and the date these were affected, and final outcome.

IX. PUBLIC CONSULTATION

A. Project Stakeholders 165. The public consultation was organized by HSIIDC in its premises on 3rd March, 2014. The stake holders from various villages were invited to take their views on the project. HSIIDC has invited the villager intimating the village heads (Sarpanchs) and the administrative authorities. Copy of the letter attached as (Appendix 4). There is no objection against this project from any invitees. The meeting was headed by Mr O.P.Goyal (Deputy General Manager, HSIIDC) and attended by Mr. Khaitan (Sr. Manager, HSIIDC), Mr. Suman Banerjee (Managing Partner, ITHC) and Mr. Soumya Dwivedi (Environment Expert, ITHC). The list of the stakeholders attended from various villages is as follows:

166. The public consultation was attended by the villagers and Sarpanchs (village Heads) of the concerned Villages. The matter was discussed thoroughly among the public by the project proponent. No objection was raised against this project. General concern amongst the villagers were whether the water distribution system will cater to their respective villages. This was addressed by the project proponent stating the proposal of distribution is for HSIIDC and the villagers will have to proceed through the local body in order to get water distribution system in their villages separately.

X. CONCLUSION

167. The project will have a number of benefits such as availability of clean and sufficient drinking water to all the residents of Manesar. With the development of the water supply systems in the town, the environmental conditions shall be significantly improved. The proposed components should proceed through to design and implementation, subject to mitigation measures and monitoring programs as per EMP for potential impacts identified in the IEE. These will be updated and detailed during detailed design stage, and based on above recommendations. It may be emphasized that the present IEE, which identifies potential impacts and EMP which presents appropriate mitigation measures, is sufficient enough to safeguard the

65

environment. There are no significant adverse impacts, which are irreversible or may lead to considerable loss/destruction of environment, envisaged. All the impacts are generic and have proven mitigation measures to minimize/mitigate the same.

Note: The suitability of surface water for use for drinking water after treatment (Class C) does not stipulate

requirement of Iron. The treated water should not exceed drinking water standard for iron. If we look to water quality report of treated water then it is clear that the iron content is within the permissible standards.

The coliform limit for C class water (untreated) is 5000 MPN/ML i.e., 500000/100 ML. The actual coliform as per the test report for inlet of WTP is less than 500000/100 ML. As such the source water is suitable for drinking water of course after treatment. After the treatment (Aeration and chlorination), the level of iron and coliform bacteria are well within the stipulated limit prescribed in IS 10500:2012 as evident from the test report of treated water.
