Mumbai’s Daily Water Requirements And Water From Mumbai’s Lakes
- Mumbai City’s daily water requirement is 4,200 million liters. Mumbai’s Municipality (BMC) supplies only 3,500 to 3,750 million liters of water per day. The gap between demand and supply is met by tankers, wells, bore wells, rain water harvesting, etc.
- Formula used by BMC to determine daily water requirement in Mumbai is 135 litres per person in housing societies, 45 litres per person in slums (almost 50% of Mumbai),135 litres per hotel bed and 70 litres per restaurant table.
- With a capacity to filter 2,100 million liters of water per day, the Bhandup water treatment plant is the largest such treatment plant in Asia. 4 water treatment plants supply water to Mumbai.
- According to the Chief Minister of Maharashtra, 900 million litres of water is wasted everyday in Mumbai. This wastage occurs because of leakages in pipes and theft of water. After this loss of water, BMC is able to supply around 975 million litres of water to the main city (population of 3.1 million), 930 million liters to Mumbai’s Eastern suburbs (population of 3 million) and only 620 million liters to the Western suburbs from Goregaon to Dahisar (population of 3 million).
- Mumbai’a Water distribution network is 6,000 Km long. This amazing water network is designed in such as way that almost all the water distribution is done via gravity.
- 7 lakes that supply water to Mumbai are Bhatsa Lake (built in 1983), Upper Vaitarna (built in 1973), Middle Vaitarna (built in 2012), Tansa Lake (built in 1925), ModakSagar Lake (built in 1957), Tulsi Lake (built in 1879) and Vihar Lake (built in 1860).
- The total annual water capacity of Mumbai’s 7 lakes is 14,47,000 million liters. Of these 7 lakes, only Tulsi Lake and Vihar Lake are within Mumbai city.
- Bhatsa Lake provides water to the Eastern part of Mumbai, whereas the other lakes provide water to the main city of Mumbai and the suburbs. Bhatsa also supplies water to Thane.
- The two biggest water sources for Mumbai – Bhatsa Lake and Upper Vaitarna – are managed by the Maharashtra state government. The balance 5 Mumbai Lakes are managed by the MCGM.
- Damanganga – Wagh – Pinjal water linking project and the Gargai project are the major new projects to increase water supply to Mumbai. For the Damanganga–Wagh-Pinjal Project, water from Damanganga River (in Gujarat), Wagh River and Pinjal River (both in Maharashtra) will be diverted to Mumbai using 3 dams and 2 tunnels. This will augment Mumbai’s water supply by a massive 1,600 million liters per day. An additional 865 million liters per day will be supplied once the Pinjal Dam is complete. The Gargai Dam project will increase Mumbai’s daily water supply by 227 million liters.
- Navi Mumbai gets water from Dehrang Dam in Panvel and Pune gets water from Panshet Dam and Khadakwasla Dam.
In case of water related issues in Mumbai, the BMC helpline numbers are South Mumbai (23695835, 23678109), Western Suburbs (26146852, 26184173) and Eastern Suburbs (25153258).

Flood Risk Dates In 2019 Mumbai Monsoon (High Tide > 4.5M)
In Mumbai rain water flows into the Arabian Sea through the drain system. When high tide in the sea is over 4.5 meters, there is danger of sea water entering Mumbai via the drain pipes. In such situations Mumbai’s Municipal Corporation (BMC) closes the storm drains. When this happens, there is no exit for Mumbai’s rain water. When rainfall is heavy and high tide is over 4.5 meters, there is a high probability of flooding in Mumbai.
Places that are at a low level are at a greater risk of flooding. This a link to Mumbai’s Low Lying Areas that are at risk of Flooding in the Rains.
Listed below are the flood risk dates and time when Mumbai is at risk of flooding during the 2019 Monsoon season.
