Recognizing the loopholes in sewage treatment oversight, Siddhesh Kadam directed a comprehensive tightening of Sewage Treatment Plant (STP) discharge norms. Under the new MPCB regulations, non-compliant STPs now face fines of up to ₹1 lakh, legal prosecution, and potential plant closures. These stricter norms aim to eliminate the unchecked discharge of partially treated or untreated sewage into water bodies. A key contributor to Maharashtra’s urban water pollution crisis. 

Siddhesh Kadam’s approach emphasizes deterrence through action, not warnings. By making STP accountability a core compliance issue, he has ensured that both private and municipal entities treat effluent management as non-negotiable. The updated framework also includes clearer benchmarks and inspection schedules, helping MPCB move from a post-violation response model to a proactive enforcement strategy.
