Bawana lake to be revived using recycled water

Delhi: 8 Sept, 2021 (Times of India)



Around 3 MGD recycled water from Bawana’s common effluent treatment plant will be used to rejuvenate the lake

New Delhi: Water minister Satyendar Jain visited the natural sewage treatment plant (STP) at Ghoga Drain on Tuesday. He directed the officials concerned to increase its water treatment capacity from 10 lakh litres per day to 50 lakh litres per day.
Jain said, “This STP is based on a constructed wetland system and treats 10 lakh litres of wastewater per day without electricity or additional power. The water treatment capacity of this STP should be increased to 50 lakh litres per day. The recycled water will be used for groundwater recharge by creating a lake in an adjacent area.”
The minister also inspected the area around Sannoth Lake in Bawana. He said that around 3 MGD (million gallons per day) recycled water from Bawana’s common effluent treatment plant would be used to rejuvenate the lake. The revival work is scheduled to be completed by December 2021, he added.

Jain further said that the water holding capacity of the lake would be increased so that more groundwater could be recharged.

The minister also instructed Delhi State Industrial and Infrastructure Development Corporation Limited (DSIIDC) and Irrigation & Flood Control (I&FC) department officials to clean the Bawana escape drain, which has a design discharge capacity of 680 cusecs. This task of cleaning the drain will be jointly done by DSIIDC and the I&FC department.
“DSIIDC will ensure that no untreated or unauthorised drain falls into the escape drain, while the I&FC department will ensure that the existing quality of the water flowing into the drains should be improved to meet the parameters laid down by National Green Tribunal. Weirs should be made in the drain along with floating wetlands and aerators to enhance the treatment of wastewater flowing into the drain,” Jain said.

The Delhi government has announced that the area around the lake will be landscaped and several facilities, including a playing area for children, a stepped picnic garden, a walkway, Chhath Puja ghat and an open gym, will be developed for the common public. The lake will have different species of trees around it, including Neem, Bombax, Plumeria and Acacia. This project is being executed by the I&FC department.
