Crews from EnviroWaste will be performing a smoke testing survey of the wastewater collection system citywide. These crews will be blowing non-toxic smoke into the sewer lines and manholes in order to locate broken pipes and other defects.
The smoke is non-toxic, leaves no residue and does not create a fire hazard. The smoke will not enter your house unless there is defective plumbing present or the drain traps are dry.
To help prevent smoke from entering your house, please pour about a gallon of water into any seldomly used drains. Doing this will fill the drain traps and prevent smoke from entering your home. At no time will the field crews need to enter your property and you do not need to be at home during the test.
The information collected during this survey will be used to improve and repair the wastewater collection system.
To find possible leaks in the sanitary sewer system and roof drain connections.
Is the smoke harmful?
No, the smoke is not harmful to your health in low quantities. If you have any concerns because of an adverse breathing condition please contact the MB Control Room at 305.673.7625 prior to testing.
What do you do if the smoke gets into your home/business?
If you experience smoke in your property, please alert the crew working in the area or call our MB Control Room at 305.673.7625. Once smoke appears, please open windows for ventilation. To prepare for smoke testing to take place, please check to see that all traps under basins (sink drains), washing facilities and floor drains have water in them.
I will not be at home during the smoke testing and have pets in the house, what should I do?
While the smoke is not harmful to pets, please leave several windows partially open for ventilation should any smoke enter the building due to a leak. If you have proper connections and all of the traps have water in them, the likelihood of there being any problems is minimal.
If smoke gets into my home/business, how long does it take to dissipate?
This will depend on how much smoke enters the building and how much ventilation you can provide. With proper ventilation, it should dissipate quickly.
Will the smoke obstruct the sewers?
No, the smoke is made up of a vaporous substance.
What happens if you find a bad sewer or lack of traps in a building?
This information will be documented and will be used by city staff to determine what steps are necessary to remedy the problem.
