Overview
- The Delhi government approved the Mission Yamuna investments on Sunday, May 24, 2026, and has issued work orders and begun work on projects exceeding Rs 1,000 crore aimed at Yamuna rejuvenation.
- A sanctioned Rs 860 crore package will fund 12 decentralised sewage treatment plants (DSTPs) for the Najafgarh drain that together add about 40–46.5 MGD of local treatment capacity and cover roughly 120 unauthorised colonies and nearby villages.
- Field work has started on the DSTPs under the Centre’s AMRUT scheme and many contracts include multi‑year operation and maintenance obligations to keep the plants running after construction.
- Separately, Delhi rolled out pilots from its Innovation Challenge — including 21 STR‑101 filterless units, an EV‑mounted anti‑smog gun and the PAWAN III roadside device — that Chief Minister Rekha Gupta inspected on May 23 as on‑street field trials began.
- The pilots will be monitored by NPL, ICAT and IIT teams over coming months and experts warn device limits in open ambient air, stressing that source controls for sewage, industry and vehicles remain crucial for lasting Yamuna and air‑quality gains.
