Mumbai controls several dams in Shahapur Taluka (Thane district) that deliver water to the city. The Western Ghats trap most of the moisture-laden monsoon clouds, which feed these dammed rivers. Currently, these dams/lakes deliver approximately 3.4 billion litres of water to Mumbai daily.
Tansa and Vaitarna dams supply the Southern region of Mumbai, while the rest supply the suburbs. An underground tank in Malabar Hill is used to store the water.
