Synopsis

The High Court of Delhi, acting on its own motion (suo motu), took cognizance of environmental issues in Delhi, specifically: (i) waterlogging in the Okhla area due to inadequate drainage; (ii) upgradation of Sewage Treatment Plants (STPs) to meet prescribed standards; (iii) redevelopment of non‑confirming industrial areas; and (iv) functioning of Common Effluent Treatment Plants (CETPs). The court issued directions to multiple authorities – MCD, DJB, DSIIDC, DDA, Uttar Pradesh Irrigation Department, and industrial associations – to take urgent remedial measures, file status reports, and ensure compliance. The court also directed coercive measures (including possible locking of factories) against defaulting industrial units that fail to pay their contributions for CETP operations. The matter was listed for further monitoring.
