Its Mission

The mission of the Sewer Department 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.

The Sewer Department provides high-quality wastewater treatment services in an effective, efficient, and responsive manner to protect the health of Nantucket's residents. This department is also responsible for all stormwater operations and permitting.


The Sewer Department is responsible for operating and maintaining Nantucket’s wastewater conveyance and treatment systems, which consists of two wastewater treatment facilities, 18 pump stations, and over 80 miles of sewer mains. Wastewater personnel physically inspect and verify proper operation of each pump station and treatment facility 365 days per year. Other responsibilities include bi-annual (or more frequent as required) cleaning of the sewer main pipelines using a high-pressure water cleaning truck and a mechanical rodding truck for lines with root and grease problems caused by the improper disposal of fats, oils and grease (F.O.G).


On June 1st, 2020, the Town of Nantucket’s new Sewer Regulations (CH 336) and associated Standards and Specifications (June 2020) went into effect. Anyone seeking to design and or/engineer a sewer connection or apply to connect to the Town sewer system should review these important documents, accessible via the links below.
