Later Developments :Old City:‘A’ & H&L mains laid with laterals, (sewage is carried through a siphon atChadarghat and outfall sewer to Amberpet Treatment Plant).

New City & Sec’bad:K&S trunk sewer from IDPL to Amberpet, and Kalasiguda Main fromSec’bad Station to Hussainsagar surplus nala to join K&S main.

� Musi River flows through midst of the Hyderabad Citybifurcating city as South of Musi and North of Musi.

� The entire sewage flows to River Musi throughvarious open nalas from South & North parts.

� To contain such dry weather flows in the nalas and inthe Musi River, the Ministry of Environment & Forests,GoI, has approved a project under National RiverConservation Plan of NRCD for laying suitableConveying Mains, construction of Interception &Diversion Structures on Nalas and Sewage TreatmentPlants for treatment and disposal of sewage.

PROPOSEDNRCD PROJECT PHASE-II

(Abatement of Pollution of River Musi)

42

NRCD Project Ph-II

• At the time of preparation of first project proposals, the dryweather flows in the project area was considered for 363.3Sqkm drainage basin area i.e. the area of erstwhile MCH forthe flows of 2005 horizon year for 592 Mld.

• Due to rapid urbanization, further water supply sourceaugmentation was implemented to meet the water supplydemands of Hyderabad City.

• Resulting additional sewage flows are being generated inMusi catchment area requiring additional conveying mains andtreatment facilities.

• Accordingly, as per the guidance of MoEF, GoI, the HMWSSBprepared and submitted the Detailed Project Report for Ph-IIproject under NRCD.

43

SALIENT FEATURES - NRCD PROJECT Ph-II

� Total catchment basin area considered under the project is 574.59Sqkm covering the entire GHMC area draining to Musi river. (MCHwas expanded as GHMC)

� The project area on South of Musi is - 158.43 Sqkm i.e. 27.56%

� The project area on North of Musi is - 416.11 Sqkm i.e. 72.44%

� As per the population projections, the expected sewage flow:For South of Musi – 2024 - 412 Mld

- 2044 - 503 Mld

For North of Musi – 2024 - 926 Mld- 2044 - 1324 Mld

44

� The length of the river considered for pollutionprevention is 28 Km under this project as againstthe earlier length of 14 Km in the first project.

� Now the quantity of sewage flows considered forthe treatment is 610 Mld in addition to the 592 Mldtaken up in the first project and 120 Mld capacitysmaller STPs taken up by HMDA under the LakeConservation programme.

45

The Quantity of sewage flowing in the river Musi asper the dry weather flow measurements:

� At chainage 1.0 Km - 9.7 Mld(considered at Hydershah Court)

� At chainage 4.5 Km - 96.4Mld

� At chainage 12 Km - 472.8 Mld

� At chainage 15 Km - 716.2 Mld

� At chainage 28 Km - 949.54 Mld(end of GHMC limits, Nallacheruvu)

46

Major Project Components:

� Construction of STPs.

� Laying conveying mains to STPs.

� Construction of I&D’s at Nalas to divert the sewageinto conveying mains.

47

Proposals of STPs:� The entire Musi river catchment in the limits of GHMC has been

divided into 10 sub-catchments locating the STPs for easycollection of sewage, treatment and disposal.

� The total quantity of sewage proposed to be treated at alllocations is 610 Mld.

� HMWSSB, constantly making efforts from the inceptionto strengthen the sewerage system of Hyderabad Cityin order to control the pollution levels caused due toincreased sewage flows generated in Hyderabad cityon account of rapid urbanization.

� The measures includes; laying of suitable sewercollection network consisting laterals, branch mains,trunk mains and large conveying mains & constructionof STPs for treatment of sewage to the riverdisposable standards.

52

� On implementation of NRCD Project Phase-I, thesewage pollution levels in the Musi River have comedown to the significantly with treatment of sewage tothe extent of 650 Mld through various sewagetreatment plants.

� Further Improved sanitation facility through NRCDPhase-II would be achieved to the citizens ofHyderabad, thereby maintaining hygienic conditions inthe habitation and improved hydrology in the river.

� Sewage treated to river disposable standards to be letinto river Musi facilitates further prevention of pollutionin the downstream of Musi river.
