Town to Conduct Smoke Testing on Sewer Lines – No. Main St., So. Main St., & Wolcott St.


As part of an ongoing evaluation of the Town’s wastewater collection and treatment system, the Hardwick Wastewater Dept. will be conducting smoke testing in areas of the main collection system on Wednesday, October 2 or Tuesday, October 8, 2019 (weather dependent) An inspection team made up of Town personnel, and a field technician from the Vermont Rural Water Association, will be conducting the test for the Town in three areas: Wolcott Street, North Main Street and South Main Street. The purpose of the smoke testing is to locate sources of storm water inflow entering the wastewater collection system during heavy rainfalls. Smoke testing is one of the most efficient and cost-effective ways to locate these inflow sources. Residents and businesses will receive ample notification (door hangers and personal visits) prior to the testing. The testing consists of forcing a special, non-toxic, smoke into the sewer lines and observing where it escapes in order to determine the location of leaks and inflow inlets. The smoke is manufactured for this purpose and leaves no residuals or stains, and has no effect on people, plants or animals. The smoke may be seen coming from vent stacks on buildings, street drain inlets, holes in the ground, and roof leaders entering the building plumbing system; however, smoke should not enter homes or businesses. If the smoke does enter a building, there may be good reason to assume that defective plumbing or a dried-up drain trap is the cause. It is advisable for residents to run water into all drains for one minute, especially those used infrequently, prior to the smoke test period. Residents experiencing smoke within their home should contact a licensed plumber to identify and correct any possible defects. For more information about smoke testing, please contact the Hardwick Wastewater Operator at 472-5939. If there is any individual in your home or business who has respiratory problems or is immobile, please contact the Wastewater Dept. prior to the testing.
