Delhi LG Vinay Kumar Saxena recently reviewed the progress of the work regarding the desilting of trunk sewer lines and trapping of sub-drains falling into the Najafgarh drains.

WD News: Desilting of 32.58 km out of the 90.34 km of the trunk/peripheral sewer lines has been completed and the remaining work will get over by June this year, as per a statement issued by Delhi Lieutenant Governor’s (LG) office.

The L-G has directed that the remaining 530 kms of sewer lines is to be completed by the end of this year.

Shri Saxena, who is also the chairman of NGT-appointed High-Level Committee (HLC) for the rejuvenation of river Yamuna, reiterated that the flood plains and Ghats of the Yamuna will be cleaned by June 30 this year, while other works will continue simultaneously.

“It has been established that about 70% of pollution in the Yamuna is due to the untreated sewerage brought into the river from the Najafgarh drain. The Najafgarh drain, in turn, gets this untreated sewer from the sub-drains falling into it,” read the statement.

The root cause of this untreated sewage is the fact that the trunk and peripheral sewer lines have been choked to as much as 90% of their capacity due to their desilting not having been carried out by the Delhi Jal Board for the last eight years. Choked and silted sewer lines lead to sewerage overflowing into storm water drains that fall into the Najafgarh drain, the release said.

Further, as per the statement, these sewer lines which are supposed to be desilted and cleaned on a regular basis are supposed to carry the sewerage to STPs for treatment, before reaching the Yamuna.

Desilting of 32.58 km out of the 90.34 km of the trunk/peripheral sewer lines has been completed and the remaining work will get over by June this year, as per a statement issued by Delhi Lieutenant Governor’s (LG) office.
