    CPCB Sewage Discharge Standards

    Central Pollution Control Board (CPCB) is the regulatory authority and mandates the treated water quality for any STP in India. The discharge standards stipulated in 2015 have been diluted making it easier for STP owners. The changed norms are:

    Discharge standards revised on 13-10-2017
    Parameter Units Old Revised Outside capital city    
    pH   6.0 to 8.5 6.5 to 9.0 6.5 to 9.0    
    BOD Mg/L 10 < 20 < 20    
    TSS Mg/L 10 < 50 < 100    
    Fecal Coliform  MPN NIL < 1000 < 100*    

    How does it impact you? / What it means to you as STP owner?

    1. You no longer need advanced membrane filtration equipment like Ultra-Filtration. Any properly designed and operated STP can give you out put to meet the revised norms. This saves you on capital cost & operating cost.

    2. You do not need multiple dis-infection equipment like UV / Ozonation etc. Proper chlorination will be sufficient to meet the Fecal Coliform standard of less than 1000 in 100 ml sample.

    3. *If you are located outside state capital, the standard for Total Suspended solids is lower at 100 Mg/L. This means there is no need for Pressure  Sand Filter to reduce suspended solids. This reduces the operation and maintenance by 50%. If the plant is automatic, there is no need for a dedicated operator. This saves trouble of getting trained manpower for STP operation along with huge cost.
