DJBinvites bids for 13 decentralised STPsto clear up Yamuna

In a bid to rejuvenate the Yamuna river, the Delhi Jal Board (DJB) has invited tenders for 13 of the 34 proposed decentralised sewage therapy vegetation (DSTPs) geared toward treating wastewater from unauthorised colonies and peripheral villages, a senior authorities official advised The Hindu.

The long-pending DSTP challenge, conceived to deal with untreated sewage flowing into the river, has been delayed primarily as a consequence of land availability points. Officials stated the DJB has now secured land for 30 of the 34 proposed websites, whereas the Delhi Development Authority (DDA), beneath the Central authorities, is anticipated to allot the remaining plots quickly.

More tenders coming

In July, Union Home Minister Amit Shah chaired a high-level assembly on Yamuna cleansing and directed the Delhi authorities to just about double its sewage therapy capability to 1,500 million gallons per day (MGD) by 2028.

According to the official, regardless that the variety of DSTPs has been diminished to 34, their “mixed capability has been elevated to 160 MGD” to make sure the identical catchment areas are lined.
