The Brihanmumbai Municipal Corporation (BMC) has outlined the scale and complexity of the city’s water supply system, which currently provides 4,000 million litres of water per day to residents through a three-tier distribution network spanning nearly 5,000 km, a statement issued by the civic body said. 

Mumbai’s water comes from seven major sources located 100 to 175 km from the city: Vehar, Tulsi, Tansa, Modak Sagar (Vaitarna), Upper Vaitarna, Middle Vaitarna, and Bhatsa. Together, these reservoirs contribute to the city’s massive daily water supply.
