The Delhi Jal Board last year came up with a 45-point action plan to clean the river, with one of the recommendations being adoption of in-situ technology.

"Till the time more long-term measures like construction of sewage treatment plants are taken up, we plan to initiate this project on five drains across the city," Singh said, asserting that the government is working to strengthen water and sewerage infrastructure and improve the quality of Yamuna water.

For the pilot project, the DJB will rope in IIT-Roorkee for in-situ cleaning at the Defence Colony drain.

"The water running in these drains will be cleaned with the help of nano technology, which will filter and treat the water in-situ. If the project is successful, we will implement it in bigger canals like the Najafgarh drain," the minister added.

In Delhi, there are 22 big drains that flow into the Yamuna. These include the Najafgarh drain the largest of the lot besides Shahdara, and the Supplementary drains.

According to officials, in areas where large-scale STPs cannot be constructed due to space limitations, the DJB plans to install 40 decentralised sewage treatment plants , ensuring localised waste management.

The Delhi government has already approved setting up 35 DSTPs, and there are further plans to construct 10 additional STPs to reduce the amount of sewage entering the river, officials said.

In Delhi, the Yamuna flows for 52 km, of which a critical 22-km segment from Wazirabad to Okhla is highly polluted and has become the focal point of multiple policy efforts.
