Baltazar Contractors Excavating Sigourney Street.

Across the MDC’s sewer system, more than one billion gallons of a mix of storm water and sewage overflow into the Connecticut River, and eventually into Long Island Sound, annually. Other than the fact that this pollution is unhealthy,  regulatory changes stipulate that these overflows violate the Clean Water Act.

Most sewer systems in the Northeast, including the Greater Hartford Region,  face similar issues of sewer overflows. Consequently, the MDC was issued a federal consent decree from the EPA and a consent order from the Connecticut DEP, which required the District to develop a a Long-Term Control Plan for the abatement of Combined Sewer Overflows (CSOs), (sewage overflows from pipes that carry both sewage and stormwater), and eliminatation of Sanitary Sewer Overflows (SSOs), (overflows caused by either insufficient capacity and/or excessive inflow and infiltration of storm water into the sewer system).

As a response to the government mandate, the MDC developed the Clean Water Project.
