Legal Action Initiated Over Inadequate 1 MLD Sewage Plant at Pashan Lake

09 Apr 2026

 

Pune Municipal Corporation (PMC) is facing intense backlash from activists and residents who allege that untreated sewage is being allowed to contaminate the ecologically sensitive Pashan Lake. The controversy centers on a 1 million litres per day (MLD) sewage treatment plant (STP) commissioned last year, which critics describe as a product of "faulty planning." Legal experts and local residents claim the plant’s capacity was grossly underestimated for the rapidly growing area, alleging that PMC is using flow meters to divert excess, untreated waste directly into the lake, a claim the civic body has officially rejected.

While PMC officials maintain that the 1 MLD plant is functioning as designed and blame upstream inflows from Bhugaon and Bhukum (which fall outside city limits), residents point to the thick carpet of water hyacinth as undeniable proof of nutrient-rich sewage contamination. An execution plea has already been filed against the PMC, PMRDA, and the Maharashtra Pollution Control Board (MPCB), seeking environmental compensation for the degradation of the lake. Activists argue that without a comprehensive scientific study on current sewage generation, the lake will continue to serve as a "cesspool," undoing years of conservation efforts.
