The population of Mumbai was few thousands and used to fetch water from the wells and shallow tanks. These sources tended to dry up in summer and people used to face shortage of water. On 22 nd June 1845,the local residents agitated against the shortage and bad quality of water. The British rulers appointed a 2-man commission to look into the grievances of the natives. The 2-man commission reported back within 24 hours that the water supply of Mumbai needed immediate attention.
Vihar Scheme:
This was the first piped water supply to Mumbai. Vihar lake is located in the valley at the origin of Mithi river, near village Vihar. The work started in the year 1856 and was completed in the year 1860. The total quantity supplied was 32 million liters per day (MLD). The height of the dam was raised in the year 1872 and the water supply through the lake was increased to 68 MLD.
Tulsi Scheme:
Tulsi lake is situated on the north side of the vihar lake. It is located on the upstream of vihar lake on the river Mithi. It supplies 18 MLD water to the city. In the year 1879, this scheme was commissioned. [Top]
Powai scheme:Water famine was expected in the year 1891 so Powai Lake was constructed on a tributary of Mithi river. The 4 MLD water supplies is used in Aarey dairy and for agricultural purpose because the water quality is not upto the mark.
Tansa scheme:
It was decided in the year 1886 to develop this scheme, which was at a distance of 110km from the city. This scheme was developed in 4 stages. It supplies 541 MLD of water. [Top]
Vaitarna-cum-Tansa scheme:
Vaitarna-cum-Tansa scheme came into existence in the year 1957 to meet the increasing demand of Mumbai city. It comprises of 500 m. long and 90 m. high concrete dam across the river Vaitarna. 7.2 km long tunnel was constructed between lakes Vaitarna and Tansa. The diameter of pipeline was 2400 mm. from Tansa to the city for a distance of 76 kms. The Corporation in the memory of the invaluable services has named the impoundage on Vaitarna river after notable Municipal Engineer late Shri N.V. Modak as ‘Modak Sagar'.
Ulhas river scheme:
The ulhas river scheme was started in the year 1965 to mitigate the drought conditions. The water supply to the city was increased by 90 MLD after completion of this scheme in the year 1967.
At present, as per the Govt. Instructions, this source has been handed over to Kalyan Municipal Corporation from the year 1994. [Top]

Upper Vaitarna scheme:
This project was fully commissioned in the year 1972-73 and daily supply increased by 554 MLD. It is a dual-purpose scheme, which was created in the upper reaches of Vaitarna River by constructing two dams.
The water in the river was used to generate 60 MW of power and the residual quantity was used by MCGM for water supply. [Top]

Bhatsa Scheme:
The rate of growth of the population during the year 1950's and 1960's led to development of water supply and sewerage facilities. The plan was implemented in three phases, each of these phases envisaged additional water supply from the Bhatsa river. The project also consisted construction of pumping, treatment and distribution facilities at Pise, Panjrapur and Bhandup. International Development Association and the World Bank funded the project.
Stage I: This stage of project was commissioned in 1981. It comprised of weir at Pise,. It had seven pumps each of 90 MLD.
Stage II: The stage was commissioned in 1989. This stage comprised of expansion of the pumping station at Pise and construction of pre- chlorination plant at Pise.
Stage III: During this stage additional pumps were introduced at Pise and Panjrapur. This stage was completed in 1997. The city's total water supply has reached 2950 MLD. [Top]
