“This 436 million gallon per day water will be reused in water bodies, lakes, irrigation, gardening, forests, groundwater recharge,” DJB stated.
Using modern technology, Delhi government will treat around 150 million gallons (MG) of polluted water coming from the states of Haryana and Uttar Pradesh by natural and aeration method.
In a meeting with the officials of the Delhi Jal Board (DJB) on Wednesday, Delhi Chief Minister Arvind Kejriwal discussed about smooth implementation of cleaning up the river Yamuna and reduce pollution in it by 90 per cent by March 2023. The DJB presented a detailed action plan on the reuse of around 400 million gallon per day (MGD), against the existing capacity of 90 MGD of water.
In the DJB’s statement, four major interventions devised for the cleaning up of river Yamuna are, treatment of polluted water using modern technology, tapping of wastewater in the small or big drains into Sewage Treatment Plants (STPs), improving the quality of the existing STPs and reusing of sludge and the septage from the septic tanks across Delhi in the bio-gas plants to generate electricity and gas.
There are five major outfalls carrying wastewater into the Yamuna, including Najafgarh drain, Shahdara drain, Barapulla drain, Delhi Gate drain, Mori Gate drain,” the statement said.
Apart from Delhi, Najafgarh and Shadhdara drain also receive polluted water.
With different milestones to be completed by March 2021 and 22, DJB has also planned to reduce 90 per cent pollution in the river Yamuna by March 2023.
“The STPs treat around 525 MGD of water before it flows into drains, out of which only 90 MGD is reused for different purposes. An action plan to reuse 436 MGD of water against the earlier reuse of 90 MGD has been presented by the DJB before the Chief Minister,” it added.
