Overview For Acceptance of Transported Non-Domestic Wastewater and Sludges

On May 15, 2003, the Metropolitan District (MDC) 454 Plan was approved by the Connecticut Department of Energy and Environmental Protection (DEEP) under Title 22a of the Connecticut General Statutes to accept, store and treat certain non-domestic (i.e., commercial/industrial) wastewaters and sludges transported to the MDC Hartford Water Pollution Control Facility (HWPCF) by means of an DEEP approved motor vehicle.  The MDC HWPCF is located at 240 Brainard Rd., Hartford, CT 06114.  HWPCF is the only MDC facility that accepts trucked wastewater but there are other Publically Owned Treatment Works (POTW) facilities in the state that accept trucked wastewater.

The MDC 454 Plan discusses the procedures to accept transported non-domestic wastewaters and sludges at HWPCF, which are: 1) permitted by the DEEP for treatment at the POTW, and 2) compatible with the wastewater treatment process. 

Individual facilities requesting approval to discharge transported non-domestic wastewater to the MDC’s HWPCF shall obtain approval from the MDC Environment, Health and Safety Department prior to submitting the General Permit wastewater application to the DEEP.  MDC discharge approvals typically require 5 - 10 business days for issuance.
