Shrewsbury Continues Multi-Year Sewer System Project

SHREWSBURY, MA — Shrewsbury officials and the town’s wastewater consultants, Weston & Sampson, Inc., will continue Year 3 inflow and infiltration investigations in several neighborhoods next week as part of an ongoing effort to improve the town’s sewer system.

The work is part of Shrewsbury’s 2026 Infiltration Investigations Project, which aims to locate groundwater sources entering the sanitary sewer system. Town officials said removing excess groundwater flow will help reduce the amount of wastewater sent to the regional Westborough Wastewater Treatment Plant.

Next week, investigations are planned in the Floral Street, Prospect Street, Maple Avenue, Rolfe Avenue, O’Donnell Avenue, Audubon Drive and Main Street neighborhood areas.

Residents may see crews working between 7 a.m. and 5 p.m. Monday through Friday. Weston & Sampson representatives may also need access to some properties to conduct inspections in sanitary sewer easements maintained by the town.

The work is expected to be completed during the week ending May 22.

The work will take place in the following areas: Subarea-2C, including Boston Turnpike and Lady Slipper Drive. Subarea-3F consists of Cranbrook Road, Prospect Street, Heatherwood Drive, and Hill Street; Subarea-6A includes Bailey Road, Beach Road, Beacon Street, Boston Turnpike, Broadway, Browne Road, Commonwealth Avenue, Edgemont Road, Fairlawn Circle, Gale Avenue, Gleason Road, and Gordon Road. It also includes Maple Avenue, Newton Street, Rolfe Avenue, Rosedale Avenue, Sias Avenue and Stanley Road; and additional streets in Subarea-6A, Tatum Road and Worthington Avenue.

Town officials said nighttime flow-isolation work was completed this week, while earlier manhole inspections wrapped up on May 1.

The current sewer investigations are part of a broader, multi-year sewer maintenance effort in Shrewsbury.

Previous work throughout 2025 included sewer cleaning, pipe sealing, service connection repairs and inspections in neighborhoods across town. Officials have said the ongoing maintenance is designed to reduce system failures and lower wastewater treatment costs.
