As the temperature begins to soar, and summer promise to be hot and arid, the Capital inevitably witnesses an unprecedented demand for water. The Delhi Development Authority puts current demands for water at 800 million gallons, per day (mgd), and anticipates that this will go up to 1024 mgd in 2001.Two years after the DDA approached Indian National Trust for Art and Cultural Heritage (INTACH), to come up with proposals, water harvesting along the right bank of Najafgarh drain in Dwarka sub-city has thrown up immense possibilities. regional planner and environmentalist, Mr Manu Bhatnagar, who drew up the proposal, now accepted by the DDA, points out that Delhi, like other metropolises, has resorted to over-exploitation of ground water to supplement other capital intensive and environmentally retrograde schemes of supplying water from far-off places.
