The Delhi government has cleared infrastructure projects worth over INR 1,000 crore to strengthen Yamuna cleaning efforts and improve sewage and water infrastructure across the capital. The projects include 12 decentralised sewage treatment plants in the Najafgarh region, expansion of the Keshopur sewage treatment plant, rehabilitation of an old trunk sewer line in East Delhi, and a new underground reservoir project in Rohtas Nagar. The initiatives are aimed at reducing untreated sewage discharge into the Yamuna and Najafgarh drain while improving sanitation and water supply services for lakhs of residents living in villages and unauthorised colonies.
The Delhi government has approved a series of sewage and water infrastructure projects worth more than INR 1,000 crore as part of its Yamuna rejuvenation plan. The projects are focused on increasing sewage treatment capacity, reducing untreated wastewater discharge and improving water infrastructure in several parts of the national capital. Advertisement
The approvals come at a time when the Yamuna continues to remain one of Delhi’s biggest environmental concerns. Government agencies and environmental reports have repeatedly stated that untreated sewage flowing through major drains, especially the Najafgarh drain, remains one of the primary reasons for pollution in the river. In the past few years, multiple river-cleaning plans and infrastructure upgrades have been announced, but several stretches of the Yamuna continue to face high pollution levels due to inadequate sewage treatment and ageing drainage systems.
A major share of the latest investment, estimated at nearly INR 860 crore, has been allocated for the construction of 12 decentralised sewage treatment plants (DSTPs) in the Najafgarh zone under the AMRUT scheme. These plants will collectively treat around 46.5 million gallons of sewage per day.
The largest facility, with a capacity of 17 MGD, will be developed at Mitraon. Other treatment plants will be set up in Kair, Kanganheri, Kakrola, Dichaon Kalan, Galibpur, Sarangpur, Shikarpur, Hasanpur, Jaffarpur, Kazipur and Khera Dabar.
According to officials, the projects are expected to benefit more than 121 unauthorised colonies, 35 villages and nearly seven lakh residents. The government said the new facilities are intended to prevent untreated sewage from entering the Najafgarh drain, which ultimately flows into the Yamuna River.
The Delhi government has also approved the expansion and upgradation of Phase-I of the Keshopur Sewage Treatment Plant at a cost of around INR 122 crore. The project will increase the treatment capacity of the plant from 12 MGD to 18 MGD. Officials stated that the upgraded plant will also help improve the quality of treated water in line with revised environmental standards.
In East Delhi, authorities have approved the rehabilitation of a trunk sewer line connecting Amichand Chowk to the Old Kalyanpuri Sewage Pumping Station in Trilokpuri. The project, estimated at nearly INR 57 crore, is aimed at replacing ageing sewer infrastructure that has reportedly faced repeated cave-ins and operational issues over the years. Officials said the sewer line is more than 40 years old and requires urgent strengthening to improve sewage flow and reduce maintenance problems.
Another project approved by the government includes the construction of an underground reservoir and booster pumping station in Rohtas Nagar at an estimated cost of around INR 27 crore. The proposed reservoir will have a capacity of 0.72 MGD and is expected to improve water storage and supply distribution in the area.
Past government data and pollution studies have shown that despite accounting for only a small stretch of the Yamuna’s total length, the Delhi section contributes a significant share of the river’s pollution load. Over the years, authorities have increased focus on expanding sewage treatment capacity, upgrading drainage infrastructure and improving wastewater management systems to address the issue.
The latest approvals are part of a broader push towards decentralised sewage treatment and modernisation of old civic infrastructure in densely populated areas of Delhi. Officials have also been working on drain desilting, sewer network improvements and additional river-cleaning measures in recent months to support the larger Yamuna rejuvenation programme.
