I Mumbai Water Supply Project (Bhatsa Stage I)
A pick up weir across the Bhatsa River at
Pise, just upstream of its confluence with
the Kalu and near the upper limit of tidal effects.

An intake channel leading to an intake pumping station on the right bank of the river
housing 7 vertical spindle mixed flow pumps (5 duty and 2 standby) each with a
nominal output of 91 MLD against a total lift of 97.2 m (319 ft.).

A 2235 mm. (88 in) welded steel rising main 9.2 KM (5.7 miles) long, laid
underground except for one bridge crossing, between the pumping station and the
Vaitarna/Upper Vaitarna mains at Yewai.

A treatment plant comprising of settling tanks and a pumping station comprising of 6
Nos. 91 MLD + 2 timmer 45 MLD
pump sets at Panjrapur.

A control valve complex at Agra Road Yard, a short distance upstream of Yewai on
the trunk mains alignment, where the gravity flow in the trunk mains is regulated.

A new tunnel, 5 m (16.4 ft.) dia. to carry water from the trunk mains to the Bhandup
treatment works, and new mains to reinforce the existing East-West tunnel system.

A treatment works sited on land on the shore of Vihar Lake, for all the water from the
mainland sources; consisting of 5 blocks of 24 filters operating on the declining rate
principle, together with associated chemical storage and dosing facilities, a chlorine

A treated water pumping station containing 10 (7 duty + 3 standby) 245 MLD
(vertical spindle, double suction, split-casing pumps, delivering to a new master
balancing reservoir of 245 ML capacity and 7 (5 duty + 2 standby) 38 MLD similar
pumps, delivering to Malad and Borivli reservoirs, through the second leg of the
East-West tunnel; and

Treated water mains, 2 x 2750 mm (108 in) to the master balancing reservoir and 1 x
1. 350 (54 in) main to the East-West tunnel.

II Mumbai Water Supply Project (Bhatsa Stage II)
Expansion of pumping station at Pise and installation of 7 pumps (4 working + 3
stand by) of capacity 113.6 MLD each.

Construction of pre chlorination house at Pise

Laying of an additional 2235 mm dia M.S. above ground pipeline from Pise to
Panjrapur.

Construction of full fledge 455 MLD capacity treatment plant at Panjrapur and
pumping station having 7 pump sets each having 113.6 MLD capacity.

Construction of a new master-balancing reservoir (MBR II) having 117 M.L.
capacity.

Laying of 48 KM long 2235 mm dia transmission main from Yewai MBR upto City.

Construction of 3500 mm dia. tunnel under Kasheli Creek.

Construction of 3000 mm dia. tunnel from Mahalaxmi racecourse to Malabar Hill
using tunnel-boring machine. The tunnel-boring machine for tunneling was used for
the first time in India.

Construction of service reservoir at Pali Hill Ghatkopar Hills and mortar lining of
new as well as old mains was also undertaken to improve the ‘C’ value of pipe
surface thereby increasing the discharging capacity of the mains.
