How to Clean the Yamuna

While the Delhi government has been debating on what needs to be done to clean the river, the pollution levels have only worsened. In its book Sewage Canal: How to Clean the Yamuna, published in 2007, the Centre for Science and Environment reported that the Delhi stretch of the river is not only dead but had an overload of coliform contamination. Two years later, the pollution data shows no respite to the river.    

Conserving waterbodies

Both surface and groundwater today in India and other South Asian cities is facing huge quantity and quality threat. Urban areas are facing water logging due to torrential rain. It is time to engineer the ferocious events of rain. Channelising and holding rain water must become the nation’s mission. Lakes, ponds, tanks which are built to hold water must be protected. These waterbodies not only provide drinking water, support livelihoods and biodiversity but also control the rate of runoff and subsequently control the runoff.

Research

The research as a part of COE activity at CSE includes policy research on decentralized wastewater management (DWWT), rainwater harvesting (RWH) and water efficiency (see presentation).

Lakes in Courts: Cases on Protection of Lakes

Every Indian city, worth its salt, was known by its water body. In fact, localities were named after this wealth. It made the city, because, people understood the connection between these structures built to harvest rain and their drinking water.
