13.-On channel recharge on Najafgarh drain in Delhi

Abstract

Najafgarh . Block, which constitutes the Delhi catchment of Najafgarh Drain basin, is characterized by declining ground water table and rising demand for water from growing urban and rural populations. The availability of raw water in this Block, to meet the norms laid down in the MPD-2001, through conventional means is a remote possibility because of a lack of upstream water storage on River Yamuna. Further, this Block, being at the tail end of the water supply system of Delhi, is at a disadvantage with respect to the sharing of available raw water. The Block being mainly agricultural till recently and located at the periphery of the Delhi urban area has received little consideration with regard to piped water supply. This has led to considerable exploitation of groundwater and an alarming decline'of the water table.
