The Pune Municipal Corporation (PMC) has raised alarms after discovering that the sewage treatment plant (STP) near Pashan Lake is non-operational, coinciding with reports of significant fish deaths in the area. During a site inspection led by municipal commissioner Naval Kishore Ram, the PMC served a show-cause notice to Primove Consultancy, the project consultant for the STP. This lapse has been described as a serious breach of contract, prompting a scheduled hearing on April 13, 2026, where the consultancy must provide clarification. The Maharashtra Pollution Control Board (MPCB) has also initiated an independent investigation, collecting water samples to determine the cause of the fish deaths. While the STP has a capacity of 1 million liters per day (MLD), it is overwhelmed by over 10 MLD of water from surrounding villages, suggesting that the fish deaths may not be solely attributed to the STP's failure. The incident underscores ongoing concerns regarding water pollution and the maintenance of sewage treatment facilities in Pune.
