Sewer System Smoke Testing & Inspection

Request email notification when page changes E-Notify
Inspection crews periodically conduct a physical survey of Wylie’s wastewater collection system, which includes the use of smoke testing and the opening of manholes in the street and backyard utility easements. Information from this study is used to repair and improve the wastewater collection system.

These tests are conducted on a per-neighborhood basis throughout the city. Residents are notified by door hangers and yard signage when testing is about to begin in their area. Testing can take up to 12 weeks, depending on weather and other factors.

Smoke testing is used to locate breaks and defects in the sanitary sewer lines. The smoke is non-toxic, leaves no residue, and creates no fire hazard. It is harmless to humans, pets, food, and material goods. It is best, however, to avoid unnecessary exposure to the smoke, because any smoke can irritate the nasal passages. Any irritation should be temporary and quickly disappear after exposure has ceased.

During this testing, white smoke will exit through roof vent pipes, outdoor sewer cleanouts, manholes, and possibly through interior drains if p-traps are dry or defective plumbing exists. To minimize the likelihood of smoke entering the home, residents may pour a gallon of water down seldom-used drains.

At no time do field crews have to enter homes or businesses. If a sanitary sewer line or manhole is located in easements within backyards, members of the inspection crews will need access to the backyard.
