Sewer Division Information

 

Sewage collection and treatment is the responsibility of the Sewer Division of the Department of Public Works (DPW). This division maintains and operates the City’s wastewater system. The wastewater system includes:

  • 120 miles of sewer collection system

  • 20 wastewater pump stations

  • 3 EPA permitted combined sewer overflows

  • Peirce Island Wastewater Treatment Facility

  • Pease Wastewater Treatment Facility

The City’s sewer system provides service to over 90% of the City’s developed land area. There are some areas of the City that do not have access to a public sewer system and use septic systems for wastewater disposal. The City’s collection system extends into portions of Greenland and Rye and the City provides treatment to all the wastewater from the Town of New Castle.

The City has a number of ongoing operational and capital projects as well as ongoing long term programs. Major capital projects include the upgrade to the Peirce Island Wastewater Treatment Facility, a new Headworks Building at the Pease Wastewater Treatment Facility and a major overhaul of the Lafayette Road Pumping Station. The City’s long term programs include removal of extraneous water in the sewer collection system through a sewer system evaluation survey and continued work on reducing combined sewer overflows through implementation of the City’s Long Term Control Plan.

Funding for operation of the sewer division is provided through the rate payers who contribute to the Sewer Enterprise Fund. The City has approximately 6,400 sewer customers. The City makes upgrades to components of the wastewater system through the Sewer Enterprise Fund. Many of these projects are regulatory driver and for major capital project funding needs are identified as part of the City’s Capital Improvements Plan.
