The Delhi Jal Board (DJB) will treat 95 Million gallons per day (mgd) of sewage water coming from Haryana to prevent the Yamuna from getting polluted, DJB Chairman Satyendar Jain said on Tuesday.
Jain inspected the Badshahpur drain near Najafgarh on Tuesday and said that Delhi Government has decided to treat this 95 MGD of sewage coming from Haryana via Badshahpur drain through in-situ technology. “This technology will be able to filter and treat the water in the drains themselves. This will also save the cost of making new STPs and the sewage water falling into the Yamuna can also be treated with this technology," he added.
The Yamuna receives 155 MGD (million gallons per day) of sewage from neighbouring states, which includes two large drains from Haryana.
“The Najafgarh drain carries 95 MGD of sewage water coming from Haryana through Badshahpur drain which further mixes into the Yamuna. The sewage water and industrial effluents coming from neighbouring States, if stopped from falling into the Yamuna, will be a huge step towards cleaning the Yamuna River. However, neighbouring states dump sewage from their areas without treatment, resulting in the water from the drains flowing directly into the Yamuna,” he said.
“The Kejriwal Government has taken the initiative to clean the sewage coming from other states as well. Although this work belongs to those neighbouring states only, we believe that the Yamuna River belongs to the country and not to any state, so the Delhi government has decided to treat all kinds of sewage that falls into the Yamuna," he added.
As per the estimates, the DJB is supplying 940 MGD of water against the demand of 1140 MGD of water. To augment the water supply, the DJB is also working on other aspects like construction of state-of-the-art wells, rejuvenation of lakes through groundwater recharge, installation of ammonia treatment plants etc.
