NDMC to set up 97 pits in New Delhi to help reuse rainwater

Setting up of these rainwater harvesting pits would help ease the water scarcity problem in the NDMC area. More such pits will be installed in the different localities of the New Delhi area.

New Delhi Municipal Council (NDMC) will set up 97 rainwater harvesting pits in the New Delhi area with an aim to promote water conservation.

Sharing the details of the project, NDMC chairperson Naresh Kumar said these 97 rainwater harvesting pits with the storage capacity of 1,700CUM of water will be commissioned at Chankya Puri, Sarojini Nagar and Gole Market in New Delhi area by the end of August this year at a cost of ₹3.20 crore.

“The work is in progress and the agency will maintain the pits for five years. The locations for the pits have been decided in consultation with Central Ground Water Board (CGWB) and the copolymer-based crosswave main water harvesting technology has been identified as socioeconomic solution towards the existing methods of rain water harvesting pits,” an NDMC release said.

Kumar said innovative modular-type technology will save 60% of installation time and maintenance cost will be cut down to 5%. High-void ratio of the modules gives almost 95% water storage capacity, he said.

The modular tank structure is such that land above the tank is not wasted and can be used for paved area, parking vehicles and parks, the release stated.

“Setting up of these rainwater harvesting pits would help ease the water scarcity problem in the NDMC area. More such pits will be installed in the different localities of the New Delhi area,” Kumar said.
