Yamuna facelift plan to be tried out at Barapullah

NEW DELHI: The public works department is planning on cleaning a small stretch of the Barapullah drain and developing its banks for walking and cycling. The project, first floated in 2005-06, may finally see the light of day with lieutenant governor Najeeb Jung expected to review it shortly. The proposal is being held up as a miniature version of the Yamuna channelization which civic agencies also hope to implement in the near future. PWD officials said most of the Barapullah drain is either covered or is in the process of being covered.

"This is a portion which we can do nothing about. However, the remaining 4.5km stretch from Jawaharlal Nehru Stadium to Sarai Kale Khan which is open, will be cleaned to ensure that flow of untreated sewage into the Yamuna is reduced," said an official. To clean the drain, PWD intends creating ponds at four-odd locations to ensure that the effluent remains still for at least eight to 10 hours. The still water will then be treated with anaerobic bacteria and plantations that will kill the stench of untreated sewage.

As a first step, a hydraulic study of the drain will be carried out and locations for ponding will be identified. These spots would be deepened and retaining walls will be constructed along the drain to channelize the flow of water. A treatment facility will be created nearby to treat the sewage with anaerobic bacteria.

"Increasing the depth of the drain and increasing its holding capacity will eliminate the existing problem of back flow that usually floods the nearby colonies of Nizamuddin east and west. Over the past several years the drain has not been desilted which has resulted in decreasing its holding capacity. Holding the sewage is also necessary. Ponding at four points will ensure the entire 4.5km stretch will have the same quality of water and treatment will be done four times," explained officials.

Along with this, a smaller drain running along Nizamuddin Basti will also be developed. A detailed presentation will be made on both drains in the lieutenant governor's office on Wednesday. The LG was apprised of the plan during an inspection of the Barapullah drain on Tuesday. Once this work is over, said sources, landscape consultants would be appointed to suggest how the freed space along the drain could be utilized.

"We intend converting the stretch into a non-motorized transport green corridor. The proposal has been pending for several years but this time the government is serious about implementing it," said an official.
