[ARCHIVED] Important Update from the Water & Sewer Division - Annual Sewer Investigations are Ongoing

The Town's consultants, Weston & Sampson, and contractor, National Water Main Cleaning Company, are continuing the annual sewer investigation program and will be scheduling nighttime flow isolation later this week.  

Daytime cleaning and television of sewer pipelines and inspection on sewer manholes are being conducted between 7am and 5pm. During these routine inspections, the sewer pipelines are cleaned hydraulically with a pressurized water truck and a sewer-jetting nozzle and television inspected with a closed-circuit television inspection (CCTV) camera. The vacuum pressure created by the cleaning may cause air to escape though the traps and drains of your plumbing fixtures such as toilets and sinks. These inspections are conducted between 7am and 5pm. Weston & Sampson may need to access your property to conduct the investigations in sanitary sewer easements operated and maintained by the Town. 

Nighttime flow measurements are also being performed as part of the investigations between midnight (12am) and 6am. Flow measurements only require work crews to access sewer manholes and does not require cleaning. Work crews will have a police officer detail with them at all times during nighttime flow isolation.

These investigations are being conducted as part of Shrewsbury’s 2021 Infiltration Investigations Project. The purpose of the investigations is to locate sources of groundwater entering the sanitary sewer. By removing this extra flow, Shrewsbury will reduce the amount of wastewater it sends to the regional Westborough Wastewater Treatment Plant.


Daytime work will be ongoing on Ashley Drive, Audubon Drive, Barnard Street, Boxford Drive, Browning Road, Bryant Avenue, Bunker Hill Road, Cabot Drive, Cardinal Circle, Concord Road, Crane Circle, Dalton Drive, Dana Road, Deerfield Road, Deergrass Road, Eagle Drive, Egret Circle, Essex Drive, Flamingo Circle, Forest Hill Drive, Hill Street, Ireta Road, Lenox Drive, Lexington Road, Longfellow Road, Main Street (between Gage Lane and I-290), Mallard Circle, Manor Road, Millwood Drive, Minuteman Way, O'Donnell Avenue, Old Mill Road, Oriole Circle, Oxford Drive, Pondview Drive, Ptarmigan Drive, Rawson Place, Rolling Hill Road, Sandpiper Drive, Stratton Drive, Straw Hollow Lane, Swan Circle, Tanglewood Drive, Tern Drive, Thestland Drive, Tory Drive, Tory Lane, Van Ness Avenue, View Street, Wachusett Avenue, Wachusett Circle, Wadsworth Road, Westbrook Crossing Drive, and Westview Avenue.
