Sewer Department

The Sewer Department operates and maintains Nantucket’s wastewater systems, which consists of 2 Wastewater Treatment Facilities,13 pump stations, and over 60 miles of sewer mains. The Wastewater personnel physically inspect and verify proper operation of each pump station and treatment facility 365 days per year. Other responsibilities include bi-annual cleaning of the sewer main pipelines using a high-pressure water cleaning truck and a mechanical rodding truck (some lines are on an increased frequency cleaning schedule), that have root and large grease problems caused by the improper disposal of Fats Oils and Grease. 


Our mission is to protect public health and the environment for our communities by providing high-quality wastewater-treatment services in an effective, efficient, and responsive manner.
