Water sources of Mumbai
Mumbai controls several dams in Shahpur taluk (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 deliver approximately 3.4 billion litres of water to Mumbai daily. Here are the dams supplying the city the water it needs to survive:
| Dam [1] | Year [2] | Capacity (Million Litres) |
Overflow Level (Metres) [3] |
|---|---|---|---|
| Modak Sagar (Lower Vaitarna) |
1957 | 128,925 | 163.15 |
| Tansa Lake | 1892 to 1925 | 144,000 | 128.63 |
| Vihar Lake | 1860 | 27,000 | 80.42 |
| Tulsi Lake | 1879 | 8,000 | 139.17 |
| Upper Vaitarana | 1973 | 227,047 | 603.51 |
| Bhatsa | 1983 | 710,000 | 142.07 |
| Middle Vaitarna [4] | 2012 | 193,000 | 285.00 |
The water treatment plant in Bhandup, India is the largest and oldest in Asia. Tansa and Vaitarna dams supply the southern region of Mumbai, while the rest supply the suburbs. An underground tank in Malabar Hills is used to store the water.
