Stutes of STPs in ganga basin states

The untreated/ partially treated sewage from municipalities and effluent from industries have been identified by Central Pollution Control Board (CPCB) as the main sources of water pollution in river Ganga.

CPCB has inventoried 764 Grossly Polluting Industries (GPI) in 5 States on the main stem of Ganga and its tributaries Kali and Ramganga. It is estimated that 501 MLD of wastewater is being discharged from these GPIs into river Ganga directly or through its tributaries. CPCB has also identified 144 major drains discharging sewage/ effluent directly into river Ganga. The total wastewater discharge from these drains is assessed at 6614 MLD.

According to CPCB, there are 65 STPs with installed capacity of 1232 MLD in four States (Uttarakhand, Uttar Pradesh, Bihar & West Bengal) along the main stem of river Ganga. Jharkhand does not have a STP on the main stem of Ganga. Out of the total 65 STPs, CPCB has monitored 47 STPs and observed that 10 of these STPs were non-functional. The status of STPs in the four States of Ganga basin is given in the table below:

Urban Local Bodies (ULBs) such as Nagar Parishad, Nagar Nigam, Municipal Corporation and Jal Nigam are entrusted with the responsibility for construction, operation and maintenance of STPs to ensure proper treatment of sewage and its management.
