Smoke Testing

Smoke testing is a method utilized to find potential points of inflow and infiltration (I/I) in the public sanitary sewer system that could lead to high flows during storms and snow melt events. The objective of the Engineering/Sewer Department I/I Reduction Program is to remove storm water sources from the sanitary sewer system, keep wastewater treatment costs and sanitary sewer rates low, and protect the environment.

The smoke used for testing is non-toxic and non-hazardous and is manufactured specifically for this purpose.  This type of testing is a standard method of detecting sewer defects and storm water cross connections to the sanitary sewer system. Smoke testing consists of placing a high capacity blower on top of a sanitary sewer manhole and forcing “smoke” down into the sewer system. The smoke, under pressure from the blower, travels through the sewer system and escapes through any connection, cracks, leaks, etc., along the way to reveal sources of I/I within the study area.

For your convenience, The Town of Yorktown will give notice to all residents in the affected area prior to any testing via mail or website updates. We thank you in advance for your cooperation.
