Supplemental Environmental Projects Program

Dorrs PondSEPP (Supplemental Environmental Project Program) is part of an innovative agreement reached in March 1999 to allow a phased approach to reduce sewer overflows in the Merrimack and Piscataquog rivers. The City is working together with State and Federal agencies to take a comprehensive view of other environmental problems facing the City. With this holistic approach, the City achieves greater environmental and public health benefits than with a traditional regulatory approach, with lower up-front capital costs for the City, and an opportunity for future cost savings by Manchester ratepayers.

Under a traditional regulatory approach, the City would have had to spend an additional $100 million to address sewer overflow problems. Instead, the City will complete a phased combined sewer overflow (CSO) control program over 10 years, and in addition, will complete $5.6 million in supplemental environmental projects over the next five years. This $5.6 million agreement is called the Supplemental Environmental Projects Program. Officials at the City, EPA and DES are all quite excited about this innovative approach in Manchester.
