Public Works are conducting smoke tests on the sanitary sewer system in several neighborhoods beginning Sept. 25 and ending Oct. 13. Work will be done during weekdays between 8:30 a.m. and 4 p.m.
The purpose of smoke testing is to find defects and faulty connections within the sanitary sewer system. These defects allow excess rainwater (inflow) and ground water (infiltration) to enter the system, negatively affecting its efficiency and safety.
During the testing period, smoke may be seen coming from manhole covers, storm drains, roof vents and building foundations. This simulated smoke will not stain walls or furniture, nor will it leave a residue. There is no danger of fire or explosion of sewer gas from the smoke testing process.
Simulated smoke is not harmful to your health, but may cause some temporary coughing. When possible, avoid unnecessary exposure to the simulated smoke. The smoke is also safe for pets, but it is advisable to leave several windows partially open for ventilation should any smoke enter your building. If you have proper plumbing connections and all of the drain traps have water in them, there should not be any problem.
To prevent smoke from entering your home, run water faucets for a few seconds in unused sinks, tubs and drains to fill fixture traps. Pour at least one gallon of water into each floor drain. If you have defective plumbing, no trap, for example, you should consult a licensed plumber.
If you do notice smoke in your building or home, do not panic. Open doors and windows to ventilate the premises to clear smoke. Consult a licensed plumber in the near future to identify the smoke access area – how the smoke is getting in – since smoke entering the building suggests the possibility of sewer gases entering by the same route.
Testing locations can be found on the map below. Residents in these neighborhoods have already been notified of the project. The work schedule is subject to change depending on weather and other factors.
