Mumbai has an abundance of lakes in its vicinity. The Western Ghats trap most of the moisture laden monsoon clouds which feed these lakes. However with the burgeoning population, the current supply levels are still inadequate. Here are the lakes supplying the city its daily precious liquid.
| Lake | Overflow level in metres |
|---|---|
| Modak Sagar | 163.15 |
| Tansa Lake | 128.63 |
| Vihar Lake | 80.42 |
| Tulsi Lake | 139.17 |
| Upper Vaitarana | 603.51 |
| Bhatsa | 133.00 |
The water purifying factory in Bhandup is the largest and oldest in Asia. Tulsi, Vihar lakes supply the southern region of Mumbai, while the rest supply the suburbs. An underground tank in Malabar Hills is used to store the water.
