Water sources of Mumbai
Water supply to Mumbai, India
From Wikipedia, the free encyclopedia
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.
