A new sewage treatment plant (STP) is being set up at Okhla, New Delhi, which will be the largest such plant in India.
The plant was approved by Delhi Jal Board (DJB). It will be able to treat 124 million gallons of wastewater per day and will come up at a cost of Rs 1,161 crore in three years.
The new STP will be set up under the Yamuna Action Plan – III scheme. The plant will treat the wastewater that goes into the Yamuna directly.
The STP will remove 41,200 kg organic pollutant load per day and 61,600 kg solid load per day on the Yamuna. It will cater to around 40 lakh residents.
The work has been awarded to Suez group’s Degremont.
The utility also approved setting up of another 106-MGD water treatment plant (WTP) at Chandrawal, which will help meet the demand for drinking water in the city.
The new WTP, which comes after a gap of 13 years, will be constructed at a cost of Rs 598 crore in three years.
Chandrawal Phase 2 will have the advanced technology of ozonisation and activated carbon to ensure uninterrupted working of the plant. It will be able to treat high ammonia content up to 4 ppm (parts per million) in the raw water.
Earlier, the plant had to be shut down during presence of 1 ppm of ammonia in the raw water, resulting in disruption in water supply in its entire command area.
