The Sewer Department, currently staffed by 15 full-time operators, an engineer and two administrative staff, is located at the Surfside Wastewater Treatment Facility at 81 South Shore Road. The office is open weekdays 7:00 AM to 4:00 PM, with licensed sewer operators on-call 24-hours per day, seven days per week, year-round.
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 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).
