Mission: The Wastewater Department is dedicated to collecting and treating wastewater that flows into our facility from the approximately 50 miles of sewer mains and 120 lift stations in the Town of Seabrook, and delivering a clean, clear effluent into the Atlantic Ocean. Our Wastewater Treatment Facility is located at 274 Rte 286 on the beautiful Wright’s Island


Services and Responsibilities:

The Wastewater Treatment Plant is permitted through the EPA’s National Pollutant Discharge Elimination System (NPDES)

The permit expires every five years at which time the town has to apply for a renewal. The current permit was issued in September of 2010 and is in the process of being renewed. The permit establishes the discharge limitations for the plant under the Clean Water Act. The Wastewater Department is responsible for maintaining discharge compliance and for the administration of this permit.

Other responsibilities include:    
  • Maintenance and operation of the town wide sewer system including the wastewater treatment plant
  • Maintenance and operation of sewer pump stations
