Delhi govt to treat 95 MGD sewage water flowing into Yamuna

On Tuesday, Satyendar Jain, Chairman, Water Minister and Delhi Jal Board (DJB), told the media that the Delhi government would treat 95 million gallons of sewage water every day coming to the Yamuna from Haryana.

Jain, who checked Badshahpur drain in Najafgarh on Tuesday, told the media that the Yamuna gets 155 MGD (million gallons per day) of sewage from neighbouring states, which covers two large drains from Haryana.

The first is drain number six, and the second is the Badshahpur drain. These two significant drains add to polluting the Yamuna. Therefore, the Delhi government has decided to clean these drains.

Additionally, Jain said that the Delhi government has decided to treat this 95 MGD of sewage flowing from Haryana via the Badshahpur drain via in-situ technology. This technology will filter and treat the water in the drains themselves. It will additionally save the cost of creating new STPs, and the sewage water falling into the Yamuna can be treated using this technology.

Jain further told the media that the sewage water and industrial effluents coming from neighbouring states, if blocked from falling into the Yamuna, will be a crucial measure towards cleaning the Yamuna. But, the neighbouring states dump sewage from their regions without treatment, leading to the water from the drains flowing directly into the Yamuna.

RO plant of 10 MGD will be installed in Najafgarh, via which 80% of water can be retrieved. The Delhi government plans to install a Reverse Osmosis (RO) plant.

The scheme will be executed in places where the groundwater level is high but not usable because of salinity and TDS. The Delhi government has chosen Dwarka, Okhla, Chilla, Nilothi-Nangloi, Rohini and Najafgarh for this procedure.

The areas for executing these projects have been strategically selected to use the existing system and save huge costs of laying new pipelines.
