South Shore Road Sewer Extension Project
During the spring and fall of 2022, the Town of Nantucket began the installation of new sewer and water main infrastructure along S Shore Rd. The work includes the installation of a new gravity sewer, as well as the new Sea St. Pump Station Force Main and an extension of the water main to the Surfside WWTF under separate contracts. All new pipelines are being installed within the existing town right-of-way. Construction began at the WWTF and has proceeded along S Shore Rd to Surfside Rd. Construction of the main gravity sewer line from the WWTF to the fire entrance at Sachem’s Path is now complete. Crews are working on installed service connection laterals to property lines and sewer main stubs and manholes to adjacent streets. Work is expected to continue through December. Once all of the new pipelines have been installed and tested, S Shore Rd will be repaved with new curb to curb pavement from Surfside Rd to the WWTF. Final pavement is anticipated to be completed once the new Sea St. Pump Station Force Main is also installed and tested through the area.
The new gravity sewer is being installed “dry”, which means that connections to the new sewer line will not be allowed at this time. A future pump station will need to be installed at the WWTF site to pump the future flow to the WWTF headworks. The new gravity sewer in S Shore Rd is being installed now so that S Shore Rd can be repaved one time. This new gravity sewer will provide service to some of the properties within the Miacomet Needs Area, as defined in the 2014 Comprehensive Wastewater Management Plan, and gravity service previously unavailable to properties already located in the sewer district. Additionally, this new gravity sewer line will ultimately allow for the abandonment and removal of the existing Sachem’s Path and Sherburne Commons pump stations, while also providing a new discharge location for the Abrem’s Quary pump station and removal of all three station’s flows from the Surfside Road pump station.
