Capturing Rainwater

A way to augment Chandigarh’s water resources

CSE has submitted a report on city wide rainwater harvesting for Chandigarh as a part of its work as Centre Of Excellence under the Ministry of Urban Development. Chandigarh does not have any surface water source and there is a steep decline in the groundwater levels in the city. The city has very few options for sourcing water, recharging the confined aquifers from where water is being tapped becomes a necessity. Every summer, newspaper reports quote residents residing on the second and third floors in the southern sectors of the city complaining about the shortage of drinking water.
