Yamuna Clean-Up: Decade-Delayed Sewer Project Completed
2 Dec
Summary
- Interceptor sewer project to cut sewage into Yamuna is complete.
- Project completion took nearly a decade with doubled costs.
- Full river cleanup depends on sewage treatment plant upgrades.
After nearly a decade of delays and significant cost increases, the Delhi Jal Board's interceptor sewer project (ISP) is now complete. This ambitious initiative was designed to intercept smaller sewers carrying sewage into the Yamuna River, diverting it for treatment before it reaches the water body.
The project, which began construction in 2011 after being planned in 2006, saw its estimated cost more than double from ₹1,200 crore to over ₹2,454 crore. An independent assessment has confirmed the completion of the sewage trapping aspect of the ISP.
However, the full impact on Yamuna's water quality is contingent upon the upgrade and rehabilitation of nine sewage treatment plants, including Rithala and Kondli. These crucial upgrades are projected to be finished in phases by December 2027, marking the final step in significantly reducing the untreated sewage flow into the river.
