Overview
- AAP cited an RTI-based CPCB inspection to claim all 37 sewage treatment plants failed standards, with faecal coliform reportedly hundreds of times above limits.
- The BJP-led Delhi government rejected the charge, saying the cited tests were from June and asserting recent on-ground improvements, including work at key drains.
- A new CSE report says heavy past spending did not clean the river and recommends faecal sludge management, STP upgrades, reuse of treated water, and priority action on Najafgarh and Shahdara.
- CSE reports 23 of 37 STPs are not meeting discharge norms and highlights illegal sewage-tanker dumping, noting the 22‑km Delhi stretch carries the vast majority of the pollution load.
- Adding to the political fallout, Delhi Congress chief Devender Yadav asked the LG to probe an alleged ₹6,856 crore misuse in earlier Yamuna cleanup spending.
