1 Shifting of ESRs from WTP to Rohan Kritika

Site shifted

2 Utilization of newly laid 900mm MS gravity main

Planned to be used for gravity system from Parvati BPT

3 Shifting of Sarasbag Kothi ESRs to Police lines

Existing SRs and sump proposed to be demolished

4 Transfer of supply to PCWW for area- Sangam bridge to Bund

LLR Zone Is now proposed from Jalmandir GSR to be reconstructed

5 Seminary GSRs to be supplied from Padmavati PS

Parvati PS-BPT-Padmavati- Seminary will result in higher head pumping

MAJOR ISSUES IN VADGAON


1 Utilization of WW tank as BPT

Now a BPT is proposed near Institute ESR which will supply to Ujjwal Terrace Zone. ( High Bliss ESR) and Venkatesh

Serenity ESR

2 Alignment of Gravity system from New Vadgaon sump-Sudatta Sankul-forest area

After joint site visit, the Alignments are revised

3 Non availability of site for BPT & PS at wonder city-Katraj

Pumping main from Vadgaon, to be extended.

Pumps for Agam Mandir 2 zones to be housed in New RG PS

4 Site for New RG PS shifted to Truck Terminus location

Proposals are modified with location at Santosh Nagar

MAJOR ISSUES IN VADGAON

PMC informed on November 11, 2013 that sites for Charwad vasti & Ujjwal terrace not available

Alternate site for Ujjawal Terrace-Amenity space of High bliss society

confirmed by joint site visit. Alternate location for Charwad vasti

and new BPT is considered at the site adjacent to the existing Institute ESR.

6 Additional SR at Seminary SR site

Shivneri zone divided in to 2, one from ex. Site(Brahma Amenity) and other at

Seminary

MAJOR ISSUES IN CANTONMENT


1 Revision of Bakri hill zones The capacity of existing GSR is a

constraint. The existing zones retained

2 Utilization of ex.1000mm pumping main For Sicilia

Accepted. The proposal will be modified

3 Utilization of 600mm main from Ram Tekdi-Tukai Tekadi SR

The existing pipeline will be utilized, adequate up to 2032

4 Alternative SR site for part of Cloud nine zone

One higher elevation DMA proposed to be supplied from new ESR in the

premises of Dorabji ESR Lower areas from the existing

location

The new location for 4 Ml capacity ESR identified by PMC. The design is

revised

2 Confirmation of site for Sutardhara Booster

The new site identified by PMC. The design is revised

3 Revision of Bhosale nagar, Bopodi and Model colony zones

PMC identified 3 new sites, 1 at Khairewadi & 2 at Chikhal wadi.

Designs are revised

4 Supply from Holkar WW Holkar WTP is proposed to Supply Chikhalwadi ESRs i.e. Bopodi Zone

and Khadaki Cantonment Area

5 Supply to Sangam wadi zone Sangam wadi from BA gravity system



6 Utilization of new ESR in Khadki Cant. area

Not proposed to be used in PMC area

SNDT HLR zone modified to include this.

9 Alignment of Dukkar khind SR alignment through Forest

The alignment is modified, as per joint site visit

10 Utilization of 864mm diam. pipeline from CC to Pashan

This has been utilized as transmission main, for supply to Pashan &

Panchavati SRs

11 Utilization of 711mm MS pumping main-Pashan to Sus

This will be used in the proposed gravity system from CC BPT to Sus and

other SRs



12 Supply to MAFCO & Asha nagar SRS from HLR, instead of pumping from MLR-sump

Asha nagar SR can not be supplied from SNDT HLR/Existing BPT

A new BPT in SNDT area is proposed to supply MAFCO, Asha nagar and Khaire

Wasti SRs by gravity

13 Reorganization of SNDT HLR and SNDT MLR zones

The zone boundaries are modified and designs are revised.

MAJOR ISSUES IN BHAMA -ASKHED


1 Shifting of ESRs from Wadgaon sheri PS

Two ESRS at new site-Bishops school-zones 2& 5

2 Khulewadi zone

Earlier Demand worked out based on DP and Metro corridor norms

Pump Stations

Clear water transmission

Clear water transmission mains Total Length – 247,989 m

Complicated existing system:

• Transmission and distribution often mixed (e.g. many direct tappings in transmission mains)

• WTP systems often mixed (e.g. mixing between Warje water and Parvati water at SNDT HLR,

mixing between Holkar water and Chikhali water at Vidya Nagar ESR, mixing between Holkar

transmission and Cantonment distribution at 509 chowk, …)

• Only few flowmeters, often not working (e.g. SNDT MLR pump station, Katraj pump station, …)

All these add to the difficulty in management and control of the system (e.g. impossible to assess losses)

Complaints by users for measurement of air flow

• Intermittent supply-wide variation of supply hours

• Quantity of per capita supply varies substantially, very low in North of Mula-Mutha

River

• Distribution network very old in many areas-high physical losses

• High level of Non Revenue Water

• Inadequate storage capacity

• Reservoirs working as distribution reservoirs, and also feeding other SRs using

distribution mains

• Fast depletion of reservoirs, resulting in high peak factors and small number of

supply hours

Formation of water supply zones

Existing Service Reservoirs • Maximum utilisation of the storage capacity • Identification of areas compatible to hydraulic levels • Ensure terminal pressure of 12m • Select water supply zone which maximises the use of trunk distribution mains

Proposed Service reservoirs • Prospective reservoirs are identified after study of limitations of existing service reservoirs, in terms of

location, capacity and hydraulic levels • The list of such locations was prepared and discussed with PMC • The joint site visits have been conducted, for confirming availability and precise site location • The locations jointly agreed are considered for proposals • Final selection by consultants to optimize the zone formation

Other Guidelines • Zone formation based on geographical location, ground elevation and maximum travel • Nalla as zone limit • Major roads as zone limit • Major physical barriers as zone limits, such as River, Canal, Railway line, Expressway etc. • To avoid major undulations

Clear Water Transmission System

Basic concepts in bulk transmission plan • Maximum utilisation of the existing facilities (SRs, BPTs, sumps, pumps, and transmission

mains)

• Maximum utilisation of gravity-driven systems and minimization of pumping

• Allocation of water from a WTP to SRs which are best suited in terms of o nearness of location o hydraulic level

• Avoid laying of pipelines through the congested areas

• Avoid to an extent possible, long and complex pipe networks
