SMOKE TESTING OF SANITARY SEWERS
Notice to Residents
July 25, 2022
The Town of Bellingham will be conducting smoke testing investigations in a few areas of town in the next few weeks. These investigations are being conducted to identify sources of extraneous water that discharge into its sanitary sewers.
The testing involves blowing white smoke into the sanitary sewer lines in the street and observing/recording where the smoke leaks out. The smoke is harmless, odorless, non-staining, and leaves no residue. A Material Safety Data Sheet can be provided upon request. The smoke will not enter your house or building unless there are defects in your sanitary plumbing. If smoke does enter your building, do not be alarmed. Simply open the windows, and then notify the crew in the street that smoke has entered your building. Please be assured that the smoke will disappear quickly. Prior to testing, you can reduce the chances of smoke entering your building by pouring about a gallon of water down each sink, toilet, and drain in your home. This will allow water to fill each trap (bend in the piping under the fixture), which will in turn prevent the smoke from entering the building.
The smoke testing is being coordinated by the Town of Bellingham’s engineering consultants, Kleinfelder, and will be conducted by EST Associates, Inc. Representatives of these firms will carry photo identification and EST vehicles will be clearly labeled with the company name and phone number. Field crews will be on your street within the next two weeks to perform this test. The hours for testing are between 8:00 AM and 5:00 PM, Monday through Friday. The Fire and Police Departments are being notified on a daily basis of all smoke testing work locations.
If you suffer from lung or respiratory ailments, please contact EST at (781) 455-0003 and special arrangements will be made.
If you have any specific questions regarding the smoke testing please contact Jesse Riedle, Assistant DPW Director, at (508)966-5816
Thank you for your cooperation.
