Sanitary Sewer Smoke Testing Public Notice:
PUBLIC NOTICE
To All Residents and Occupants of the Town of Fort Gibson:
The Town of Fort Gibson Utilities Department will be conducting smoke testing of the sanitary
sewer system, The testing will begin on 11-02-2026 and run through 11-3-2026 if necessary.
This study will involve the opening and entering of manholes in the streets and public utility
easements. An important task of the testing will be to locate breaks and defects in the sewer
system. The smoke will also reveal sources of where storm and ground water enter the sewer
system.
A special non-toxic smoke will be used in these tests. The smoke is manufactured for this
purpose, leaves no residuals, or stains, and has no effect on plant or animal life. The smoke has a
distinctive, but not unpleasant, odor. Visibility and odor last only a few minutes, where there is
adequate ventilation.
Because the plumbing appliances in your house or building are connected to the sanitary sewer
system, some smoke may enter your home or place of business if the:
• Vents connected to your building's sewer pipes are inadequate, defective, or improperly
installed.
• Traps under sinks, tubs, basins, showers, and other drains are dry, defective, improperly
installed, or missing.
• Pipes, connections, and seals of the wastewater drain system in and under your buildings are
damaged, defective, have plugs missing, or are improperly installed.
All residents are advised that if traces of this smoke or its odor enter your house or building, it is
an indication that gases and odors from the sewer may also enter. These can be both unpleasant
and dangerous, as well as a health risk to the occupants. Should smoke enter your home or
business, you may contact a member of the smoke testing crew working in your area.
The crew members will be able to help and check with you as to where the smoke has entered
your building. Location, identification, and correction of the source of smoke that enters your
building is urgently advised. Your cooperation will be appreciated.
The information gained from this testing will be used to improve your sewer services and may
reduce the eventual cost to utility customers.
Should you have any questions on this matter, please contact Fort Gibson Town Hall at 918-478-
3551.
