WATER SCENARIO

In most cities, centralized water supply systems depend on surface water sources like rivers and lakes.

South India (Erode, Karur, Tirupur and Perundurai Industrial Area), for instance, is dependent on water storage in 300,000 around local towns and hamlets in panchayats, where as South India gets its water from the Bhavani river, which is 95km away. Where surface water sources fail to meet the rising demand, ground water reserves are being tapped, often to unsustainable levels.
