An estimated 62,000 million litres per day (MLD) sewage is generated in urban areas across India, according to the Environment Minister, while there is treatment capacity for only 23,277 MLD as of Dec 2015. A CPCB report further reveals that the actual amount of sewage treated stands at 18,883 MLD as only 522 out of 816 sewage treatment plants listed across India were operational, as of March 2015 (even this claim of 81.1% capacity utilization seems HIGHLY exaggerated). Thus, at least 70% of sewage generated in urban India is being dumped in rivers, seas, lakes and wells, polluting water bodies and contaminating fresh water sources. Partially treated or untreated sewage is responsible for large part of the pollution in streams and water bodies. Up to 80% of water bodies could be polluted.
