DSIIDC must implement coercive measures against industrial units defaulting on mandatory CETP maintenance contributions.

Chronic waterlogging in the Okhla area caused by the Abul Fazal Drain

the technical augmentation of 11 Sewage Treatment Plants (STPs) managed by the Delhi Jal Board (DJB)

the redevelopment of 27 "non-conforming" industrial areas involving the DSIIDC, MCD, and DDA

the operational inefficiency of Common Effluent Treatment Plants (CETPs) due to financial defaults by industrial associations

1. Whether the Uttar Pradesh Irrigation Department and local authorities are adequately addressing the drainage and waterlogging issues in the Okhla area through the Abul Fazal Drain extension

2. Whether the Delhi Jal Board is adhering to timelines for the upgradation of STPs to meet prescribed environmental standards

3. What steps are required to expedite the finalization of redevelopment plans for the 27 non-conforming industrial areas

4. Whether the DSIIDC is empowered to take coercive measures against industrial associations failing to pay dues for CETP operations

The Court applied the Polluter Pays Principle and the Public Trust Doctrine, emphasizing that statutory bodies like the DSIIDC and DJB have a non-delegable duty to prevent environmental pollution and maintain public infrastructure

The Court further relied on administrative principles of inter-state and inter-departmental coordination under the National Mission for Clean Ganga framework

It asserted that administrative agencies possess the inherent power to take coercive actions, such as disconnecting utilities or locking premises, to ensure compliance with environmental and public safety standards

Regarding Okhla’s waterlogging, the Court linked the Uttar Pradesh Irrigation Department's delay in dredging the Abul Fazal Drain to public safety risks, ordering immediate safety measures like reflectors and separator walls

Analyzing the DJB’s report on 11 STPs, the Court noted that while some units (e.g., Pappan Kalan) are upgraded, several others remain in the tender stage with completion dates delayed until 2027, necessitating updated status reports

In the matter of non-conforming areas, the Court found that administrative delays in boundary demarcation (specifically in Samaipur Badli) and lack of vetting by industrial associations were stalling redevelopment; it consequently mandated the personal presence of association presidents

Addressing CETPs, the Court rejected the DSIIDC’s passive stance on revenue collection, ruling that the DSIIDC must oversee these plants and implement "coercive measures"—including disconnecting electricity or locking factories—against members who fail to contribute to the operation of environmental safeguards

(ii) DJB must provide a status report on whether STPs now meet prescribed standards

(iii) MCD and DDA must finalize redevelopment plans for 23 areas after receiving association clarifications by April 10, 2026

(iv) DSIIDC must hold meetings to finalize recommendations for coercive measures against defaulting industries and coordinate a desilting plan with DJB

The case is listed for further monitoring on May 2, 2026
