2. ABOUT CETP
Common Effluent Treatment Plant for Treating of Effluent generated by Industrial units in Waluj MIDC Industrial Area was conceived as a joint efforts between MIDC,Waluj Industrial Association and Maharashtra Pollution Control Board.
Association decided to call for a bid from relevant technical expert party for designing, erectioning,commissioning and operation of CETP.
SMS Infrastructure Limited was selected for implementation of this project on BOOT basis for 17 yrs. As per the agreement an SPV in the name of M/s. SMS Waluj CETP Pvt. Ltd. was formed.
The project is running successfully through Active co-operation from the industrial association and officials of MIDC and MPCB.
