In Wells: Dale Can’t Collect Rainwater | Daily News – Indian Times

New Delhi needs a strong rainwater harvesting (RWH) culture for a city with an estimated 400 million gallons of drinking water per day or 32% of daily needs and groundwater overuse. However, when the TOI visited some places, the picture associated with this simple and effective water conservation system was very muddy.
Officials at the Del Jal Board say they do not have information on RWH on private buildings and colonies, but most public buildings have no way to save rainwater or damaged collection pits with mud, gravel and vegetable waste.

At the ITO, an official in charge of the Vikas Bahawan Department of Public Works shook his head. “There is no rainwater collection system here. Rainwater flows through external sewers. We do not know if there is a system,” the official said. Cannot be used.
According to the regulations of the Department of Urban Development, all buildings constructed of 100 square meters and above since 2001 must have an RWH system. But there are flaws everywhere. The entrance to the assembly hall at the Deli Public School in Dendall Uppadዪ Marg was filled with dirt and strangled with mud. At AIMS Square, the system had large stones and fruit and vegetable waste that blocked the water supply to catch flies.
In the shopping mall at Nelson Mandela Marg, the entrance points are closed by construction debris. “Three groundwater wells have been drilled, but we do not know if they are still working,” said Sonya Bison, an environmentalist and resident of Vasanth Kunj. She said a water pump in the mall was now parked and was not clean.
Many RWAs have said so, recalling plans to take rainwater harvesting years ago and that the plans never started. According to BS Vohra, President, East Reliers Federation, 100 RWAs, “In 2012, there was an initiative to install a rainwater harvesting system in our area. Nearly five wells have been drilled in the parks, but never expected. Now, there are several RWAs in Delhi. We have written to the Delhi government, but we have not heard from anyone yet.
Rainwater harvesting is one of the key elements of the Deli government’s plan to provide clean drinking water 24 hours a day over a three-year period, but acknowledged that the 2022-23 government budget RWH has not yet been taken seriously.
According to the Deli Economic Survey 2021-22, DBB RWH has been implemented in 594 water service facilities. Out of 4,778 schools in Delhi, 3,687 have been harvested. RWH equipment is being built in 413 schools, and similar work is underway in 449 institutions.
However, there is no mention in the study of the adoption of the technology in the private sector and things are not going as fast as they should.
According to Sushmita Sengupta Deputy Program Manager (Water) Science and Environment Center, 118.4 mm of rainfall will enable the city to produce 87,000 million liters of water. “There is a huge potential for rainwater harvesting in Delhi. However, roofing is not the only requirement.”
A.D. In 2021, according to the Indian Meteorological Department, Deli recorded an annual rainfall of 1,526 mm at Sefdarjung Meteorological Station, the 121st. But all this water often does not save, says water expert Rajendra Singh. “The disadvantage is the lack of monitoring. Then there is corruption. Therefore, homes will receive a building permit without RWH. “Delhi has the moral right to fight other states for water only if it can save itself rainwater,” Sing said.
In addition, 78% of Delhi’s underground reservoirs are over-designed, Sing said, adding that production will continue to do so despite low inputs.
Despite repeated attempts by the regional government to comment on the maintenance of buildings and rainwater harvesting, the DGB did not respond. “Steps are being taken to install water harvesting plants on the roofs of buildings and parks under the civic body in the New Delhi area,” the NDMC official said.
