Residents of Greater Kailash-I seem to have found a novel way to battle the persistent problem of water-logging in the area.
The Resident’s Welfare Association (RWA) of the R-Block in Greater Kailash (GK) -I is building rain water harvesting tanks at places where water logging is a big problem.
“We are constructing plants where water logging is common. This way, water will not stay on the roads and will get accumulated in the tanks,” said U.C. Mathur, secretary of the RWA.
The water will get filtered once in the tanks and will then be released into the ground.
“We are not using the water for consumption. It will be released into the soil,” said Mathur. The colony already has two water harvesting tanks, one of which has addressed the problem of water logging.
The third one is under construction and will be functional by May-end.
Construction of one plant costs Rs 2 lakh, for which residents have collected money through donations.
The Central Groundwater Board helped residents with the design and the plan of the project.
“Through water harvesting tanks, the residents have managed to solve the problem of water logging,” said Jyoti Sharma, president, (FORCE), a Delhi-based NGO working on water-related issues.
But it is not just the streets that have improved. The water table in the area has also risen, as rain water is being pumped back into the soil.
“The technique of pumping back water into the earth is called recharging. In many cases, it helps arrest the depletion of the water table. It is very feasible,” said Mehrajuddin Ahmed, senior research associate, Centre for Science and Environment.
“Our organisation carried out an assessment of the water table in the area and found that it rose considerably. The rise is local and its effect reflects directly in the water supply in the area,” said Sharma. The residents agree. “The bore wells that had dried up are now supplying water regularly,” said Yunus Ali, a resident.
