In order to improve sewer service, on behalf of the Town of Shrewsbury, Weston & Sampson will be conducting smoke testing on portions of the sanitary sewer system from 8:00 a.m. to 5:00 p.m., Monday through Friday, between August 22 and September 30, 2016. Testing will be performed in selected areas of Town.
The inspection is being conducted as part of Shrewsbury’s 2016 Inflow Investigations Project. The purpose of smoke testing is to locate sources of rainwater 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.
During the test, white smoke is introduced to the sanitary sewer system via a smoke-generating machine. During this procedure, white smoke will be venting from holes in manhole covers located in the street and from plumbing vent pipes located on or near roof surfaces. THIS IS NORMAL AND SHOULD NOT CAUSE ALARM.
