Smoke Testing 

The City of Frisco will be performing “Smoke Testing” on the city’s sanitary sewer system on an annual basis. The smoke testing project is part of a 10-year study to locate possible leaks, breaks, and defects in the sewer system.

Frisco Police and Fire Departments are aware of the areas and the daily schedule for the smoke testing activities. Testing will occur between the hours 9:00 AM and 3:00 PM.

The city is working with crews from Burgess and Niple (B&N) to conduct the sewer inspections. Crews may need to access sewer manholes in utility easements. Whenever these lines require investigation, members of the inspection crews will need access to the easements of the sewer lines and manholes. B&N personnel are uniformed and carry identification badges.  Homeowners do not need to be home and at no time will field crews have to enter a home or business.


What to Expect
You may observe smoke coming from vent stacks on houses or holes in the ground. The smoke is harmless, has little odor, and creates no fire hazard. The smoke should not enter your home unless you have defective plumbing or dried up traps. If this occurs, you should consult your licensed plumber.

If the harmless smoke should enter through faulty plumbing, the potential exists for dangerous sewer gases to enter your home or business. Should the smoke enter your home or business, contact a representative of B&N at (972) 620-1255 ext. 6040. A crew member can check the sewer lines around your home or business to possibly determine the source of the smoke. Photographs will be taken of leaks occurring in the system.

If you receive a yellow “Smoke Testing” flyer, it is to inform you that the “Smoke Testing” survey will be conducted in your area. The information gained from the testing will be used to improve the quality of your wastewater collection system.
