The Delhi Jal Board (DJB) project with the aim to revive lakes in the city is inching closer to its objective to rejuvenate about 50 water bodies in the city by the finish of the year. Around 17 water bodies out of 50 are almost completed.
Talking about Paschim Vihar, a Rs 10 crore project is beneath way to lay a 4-km lengthy pipeline from the remedy plant at Keshavpuram to replenish the lake with treated water. Among the other projects, a drain building is also underway alongside the Bhalswa Lake to divert wastewater into an STP. The project got approval just lately. Work on the Roshanara Lake is most probably to start in the next 30 days. And pipelines are becoming laid at the 50-acre Tikri Khurd lake in North Delhi from the STP at Narela to recharge the lake.
Rejuvenation of the city lakes suggests a compact water remedy program connected to the water body, or pipelines are taken from an current sewage remedy plant (STP) close to the water body, to make certain a perennial supply of treated water that is match for groundwater recharge. As per the DJB, ponds of about 1 to 1.5 acres are ‘water bodies’ and bigger than that are lakes. To make certain the supply for water, lakes are becoming connected to current remedy plants.
There are some water bodies on the list that are awaiting energy connections for adjoining remedy systems. This program, which is a ‘natural’ STP in most instances, will draw wastewater from nearby places, treat it, and feed it into the water body. A all-natural STP is a sedimentation tank that removes water pollutants. Floating rafters are made use of in some instances to treat the water.
Launched in 2018, this ‘city of lakes’ project constructed to augment water provide by recharging ground water and recycling treated wastewater to meet the city’s water demand of 1,140 million gallons (MGD) per day. The present provide is 940 MGD falls and is quick adequate to meet the water demand by 200 MGD. Setting up new groundwater recharge reservoirs and rejuvenating current lakes was the major objective of the project.
The DJB has allocated an quantity of Rs 376 crore for 155 water bodies, and about Rs 200 crore for a different 90 water bodies, officials connected with the project stated.
Lakes, like the ones at Rohini and Timarpur, have separate allocations of about Rs 64 crore each and every and about Rs 10 crore has been allocated for the Bhalswa Lake.
Delhi has more than a 1,000 water bodies but only about 600 of these can be “revived” considering the fact that the remaining have been constructed more than or turned into parks. Of the 600, about 255 water bodies have been integrated beneath Phase I of the project.
Currently, about 500 MGD of wastewater is becoming treated at 35 of the DJB’s STPs in the city. This is anticipated to go about 630 MGD by the finish of the year with the compact remedy plants that are becoming installed alongside water bodies.
