AERIAL VIEW OF CETP

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.
