Mystic Sewer Smoke Testing

The Town of Stonington WPCA has contracted with engineering firms CDM Smith and Martinez Couch & Associates to perform sewer smoke testing within the Mystic Sewer shed as part of our ongoing sanitary Inflow and Infiltration study. Sewer smoke testing is done to locate direct and indirect connections to the sanitary sewer system from sources such as catch basins, roof drains, sump pumps, broken sewer pipes, etc. These direct and indirect connections cause excessive flows on the treatment plant, which decreases plant capacity, increases costs, and adds stress to pumps and other equipment. 

During testing, white smoke is introduced into the sanitary sewer system via a smoke generating machine through an existing manhole. This smoke is very similar to smoke used at haunted houses, weddings, concerts, and other special events. It is NON-TOXIC and NON-STAINING. Should smoke be detected within your building, do not be alarmed. Please notify Martinez Couch and Associates at (860)929-7641, and they will assist you in locating the source where smoke has entered the building.

Smoke testing will be performed on Monday July 18^th and Tuesday July 19^th between the hours of 7AM and 5PM. Weather permitting. Informational flyers will be hand delivered to buildings in the sewer smoke testing area on Thursday July 14^th.  The streets where sewer smoke testing will take place are as follows:

• Mistuxet Ave. from Greenmanville Ave. to Brown St.
