[ARCHIVED] City of Harrisonville to conduct smoke test of sanitary sewer system

Smoke testing

The City of Harrisonville is working with Ace Pipe Cleaning to conduct smoke testing of our sanitary sewer systems. The smoke is non-toxic, non-staining, has no odor, white to gray in color, creates no fire hazard and is not harmful to pets. The smoke should not enter your building unless you have defective plumbing or dried up drain traps.

Testing will begin on Wednesday, November 2.

Here is a map of the areas that will be tested.

Ace Pipe Cleaning will be communicating with any residents and businesses located inside the areas on the map. Ace will distribute door hangers and letters detailing their work and providing contact information for those who have questions.

The testing blows a non-toxic vapor through the sewer pipes to locate breaks in the sewer revealed by escaping smoke. 

Locations for defects may include:

  • Defective service pipes
  • Driveway drains
  • Foundation-perimeter drains
  • Roof downspouts
  • Stairwell drains
  • Uncapped clean outs
  • Window well drains
  • Yard or area drains

The sanitary sewer system was not designed to handle stormwater. The stormwater in the sanitary sewer system creates an issue called INI (inflow and infiltration), which can cause sewage backups and results in extra water being treated at the wastewater treatment plant. This issue can cause increased sewer charges on your utility bills. These tests help us identify breaks and defects in the sanitary sewer pipes that allow for INI.
