New housing projects in Pimpri Chinchwad may soon be required to connect their sewage treatment plants to PCMC's drainage network before obtaining completion certificates under a new proposal moved by the civic body's environment department before the general body for approval. Under the proposed policy, PCMC will verify STP connections and charge Rs 10,000 per project for linking plants to the civic drainage network before issuing the completion certificate. The move aims to prevent excess treated effluent from being discharged into stormwater drains and eventually reaching rivers, a gap that exists because current UDCPR rules require functional STPs before completion certificates but have no mechanism ensuring those STPs are actually connected to the civic drainage system. Officials said excess treated water from housing societies is sometimes discharged into stormwater drains, which ultimately flows into rivers, and the new policy seeks to make the connection mandatory for all new projects.
Existing housing societies will also be allowed to voluntarily connect their STPs to PCMC's drainage network, helping them avoid penalties for discharging untreated effluent into stormwater drains or open spaces. PCMC officials said all drainage lines pass through the corporation's existing STPs ensuring that only treated water is eventually released into rivers once the connection is in place. The civic body already imposes fines and in cases of repeated violations disconnects water supply to societies releasing untreated effluent into stormwater lines. The new mandatory connection policy, if approved by the general body, will significantly strengthen enforcement by building compliance directly into the completion certificate process rather than relying on post occupancy inspections that have historically been inconsistent and easy to evade across Pimpri Chinchwad's rapidly growing residential landscape.
