In a bid to rejuvenate the Yamuna river, the Delhi Jal Board (DJB) has invited tenders for 13 of the 34 proposed decentralised sewage treatment plants (DSTPs) aimed at treating wastewater from unauthorised colonies and peripheral villages, a senior government official told The Hindu.
The long-pending DSTP project, conceived to tackle untreated sewage flowing into the river, has been delayed primarily due to land availability issues. Officials said the DJB has now secured land for 30 of the 34 proposed sites, while the Delhi Development Authority (DDA), under the Central government, is expected to allot the remaining plots soon.
More tenders coming
“The DJB is also in the process of floating tenders for 15 more DSTPs and estimates for the remaining six are under way. Once completed, most areas currently discharging untreated sewage into the Yamuna will have local treatment systems,” the official said.
The decentralised plants are designed to treat sewage near its source, unlike the city’s 37 large treatment plants that require wastewater to be pumped across long distances through extensive pipelines. Each DSTP will serve three to five nearby villages or unauthorised colonies, reducing both conveyance costs and leakages.
