Chief Minister Rekha Gupta holds a high-level review meeting with officials on Wednesday. Rekha Gupta reviewed the current condition of the Yamuna, sewage treatment, drain cleaning, and the laying of sewer lines in unauthorised colonies.
Minister Pravesh Sahib Singh and senior officials from the Delhi Jal Board, PWD, Municipal Corporation of Delhi, Delhi Pollution Control Committee, DDA and other concerned agencies were present during the meeting.
Chief Minister Rekha Gupta said that the Yamuna is not merely a river, but the lifeline of Delhi. The government is continuously working to rejuvenate it through scientific planning, fixed timelines, and coordination with neighbouring states.
A key pillar of the plan is a massive expansion of Delhi’s sewage treatment capacity.
Officials informed 56 MGD capacity will be added by upgrading existing STPs by December 2027. In addition, 35 decentralised sewage treatment plants (DSTPs) will add another 170 MGD. Large new plants near major drains will further contribute around 460 MGD by December 2028.
At present, 37 sewage treatment plants (STPs) together treat about 814 million gallons per day (MGD) of wastewater. The government has set a far more ambitious target of raising capacity to 1,500 MGD to cater to future needs.
“This expansion will ensure that untreated sewage no longer flows into the Yamuna,” Chief Minister said, stressing that improved treatment capacity will directly translate into better water quality, reduced pollution and revival of aquatic life. In the long run this would also protect drinking water sources and public health, Gupta added.
PWD Minister Pravesh Sahib Singh said that under the Yamuna Rejuvenation Mission, all works related to major drains and sewer networks will be completed by 2028. He said departments are working under an integrated, time-bound action plan, with DDA land support enabling rapid expansion of the sewer network across the city.
The government has also accelerated sewer-laying work in unauthorised colonies and JJ clusters, which remain a major source of untreated wastewater. Out of 675 JJ clusters, sewer work has already been completed in 574, while single-point sewage collection arrangements are being put in place in 65 more.
Work in all 1,799 unauthorised colonies will be completed in phases between December 2026 and December 2028.
Chief Minister said for the first time, a comprehensive monitoring system has been introduced for Delhi’s drains. Teams from the DPCC and the Central Pollution Control Board are conducting monthly water quality tests at 47 identified hotspots.
Drone surveys of minor drains connected to the Najafgarh and Shahdara drains are scheduled to be completed by January 2026, while the remaining drains will be mapped by June 2026.
The aim is to accurately identify pollution sources and volumes so that corrective action can be taken in a targeted manner.
