Webster Avenue Sewer Pump Station Improvement Project

Project Background

The Webster Avenue Pump Station pumps sewage from the Portsmouth Avenue sewer-shed over Jady Hill to the sewer collection system. It is then transported across the Squamscott River, via two sewer siphons, to the Main Pump Station on Water Street.  From there, it is pumped to the Town's Wastewater Treatment Facility off Newfields Road. This project will upgrade and increase the current flow capacity at the Webster Avenue sewage pump station from 800 to 1,200 gallons per minute.  Improvements will also include deepening the wetwell at the pump station and installing a new 12-inch HDPE force main from the pump station, up Webster Avenue, and down Jady Hill Avenue to House #55. 

This project is being done in conjunction with the Squamscott River sewer siphon project, which is expected to be completed in August 2024. 

Funding for the project was authorized by voters at the 2020, 2022, and 2024 Town Meetings, under articles 5, 3, and 6, respectively. Funding sources include a $1,050,000 Congressionally Directed Spending request, $1,395,000 State ARPA appropriation, $3,255,000 Clean Water SRF loan, and $213,300 SRF Amendment.

Typical working hours are 7:00 am to 5:00 pm, Monday through Friday.  Noise and vibration from trucks and heavy equipment are expected. The Town has hired the engineering firm, Wright-Pierce, to assist with construction observation and administration. We appreciate your patience and cooperation during this important project.
