There have been at least three incidents of leakages from fly ash dykes at Reliance’s Sasan UMPP in MP & NTPC’s Unchahar Plant in Raebareli, UP in Aug. 2026. All the three incidents have considerably affected nearby village and farmer communities in both the states. Notably, both projects have also experienced ash dyke related leakages and failures in the recent past, raising serious concerns over safety of the structures and safe disposal of the toxic fly ash.

DRP 060726: India needs to improve Rainfall Monitoring?
(Feature Image: A manual rain guage in Syunsal village of Pauri district, Uttarakhand. Bhim Singh Rawat/SANDRP)
Two reports from Karnataka this week highlight that over half of the 6605 rain gauges in Karnataka are non-functional. Earlier we saw that IMD does not even report rainfall for at least 11 districts in Arunachal Pradesh alone, possibly since it does not have adequate number of rain gauges in those newly formed districts of Arunachal Pradesh. IMD’s Annual Report for 2025 says P 59): “IMD operates 1,008 Automatic Weather Stations (AWS), 1,382 Automatic Rain Gauge (ARG) stations, 200 Agro-AWS, 5 Automatic Snow Gauge (ASG) stations”. That comes to 2395 locations where rain or snow is measured by IMD, going by the Annual Report. IMD apparently uses rainfall data from other agencies, but their number is not given in the report. IMD also has a large number of manual rain gauges, but the IMD Annual Report does not provide those numbers.

DRP 040526: NGT acknowledges vacuous Groundwater Governance in India
It is good to see this week that the National Green Tribunal (NGT) has acknowledged the non-existent or vacuous groundwater governance in India at both central and state levels. It was long overdue. It took the judiciary almost three decades to realise this, since the Supreme Court order in late 1990s for setting up Central Ground Water Authority (CGWA) under the 1986 Environment Protection Act.
