Smoke Testing

VISU Sewer engineers working with the City of Monett will be smoke testing sanitary sewers in our area, starting Monday, November 29th, as part of the City’s ongoing efforts to improve the sanitary sewer system. They will be hanging door tags for the areas they will be testing in. The smoke is NON-TOXIC, NON-STAINING, HAS NO ODOR, WHITE TO GRAY IN COLOR, CREATES NO FIRE HAZARD, AND IS NOT HARMFUL TO PETS. The smoke should not enter your building unless you have defective plumbing or dried up drain traps.
Should you detect smoke in your building, the room should be ventilated through an open window or door and the smoke will dissipate quickly. Should smoke enter your building and you need assistance, please notify the field technicians who are conducting the test.
To reduce the potential of smoke entering your building, pour water into drains that are seldom used. Also, adding a small amount of vegetable oil will help slow down the evaporation of water in your drains. In addition if floor drains do not hold water in trap place a damp towel over drain.
Thank you for your cooperation as we work to successfully complete this important effort of locating breaks and defects in the sanitary sewer pipes.
Steps You Can Take to Assist With the Tests and Limit Smoke Inside Your Home
Why is the District conducting smoke testing?
The sanitary sewer system was not designed to handle storm water. Storm water in the sanitary sewer system can cause sewage backups and results in extra water being treated at the wastewater treatment plant, which drives up sewer charges.
What can you do to prepare for the tests?
The smoke should not enter into buildings unless leaks or plumbing defects exist. To prevent smoke from rising out of appropriately-connected drains inside your home, please make sure that traps for all basement floor drains and other sink traps and plumbing fixtures are full of water by pouring approximately 24 ounces of water in each drain.
Smoke may also enter your building around the wax ring at the base of the toilet. It is suggested that the bathroom doors remain closed during smoke testing activities to contain smoke within the bathroom.
What if you get smoke in your house?
Should you detect smoke in your building, the room should be ventilated through an open window or door. If you experience irritation caused by the smoke, leave the area and ventilate well to dissipate the smoke.
Please notify the field technicians who are conducting the test should smoke enter your building.
