A dried-up lake in North West Delhi, which was used for cricket matches and bicycle riding until a few months ago, has been revived through the efforts of the Irrigation and Flood Control (I&FC) department.
The lake, located near Bawana’s Sannoth village, stretches over three acres. The water in the lake is recycled waste water treated through a constructed wetland method, said Ankit Srivastava, technical advisor to the Delhi Jal Board (DJB) who is also involved with the I&FC project.
“It was a dry patch of land. Around 90 days ago, we started diverting water to it. The water is clear and you can see the bottom of the lake,” Srivastava said.
Constructed wetland is a method of purifying water naturally through gravel, plants and microbes.
Waste water and sewage from villages near Sannoth flows into a drain, which reaches a regulator from where water is diverted to the STP with a treatment capacity of 1 million litres per day (MLD). Water then reaches a sedimentation tank, in which solid particles are degraded and settled through bio-cultures.
It is later released into the constructed wetland, built inside a reinforced concrete water tank, following which the water passes through sand and carbon filters and is channeled into the lake.
The revived water body is connected to the STP with a pipeline stretching about a kilometre, and uses the entire 1MLD of water treated at the plant.
The lake is situated inside a six-acre park, where authorities have planted trees and saplings and further beautification is underway.
Funds of around Rs 3.5 crore have been sanctioned, officials said, for landscaping and public utilities such as developing a Chhath Ghat or an amphitheatre and installing benches and lights, among others.
The DJB and I&FC are jointly rejuvenating 259 water bodies across the capital. However, the lake in Sannoth was a compensatory revival, officials said.
Of the 259 water bodies, work is underway on 25 and a further 50 would be taken up by December 31, officials said, adding that all would use treated water from STPs.
