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. The Wastewater Treatment Facility is located at 274 Rte 286 on the beautiful Wright’s Island.

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.

School & Group Tours

The Wastewater Plant can schedule school and group tours. Tours are typically given mid-morning or early afternoon.
