Sanitary Sewer Smoke Testing What to Expect

Download PDF PDF"Sanitary Sewer Smoke Testing" cover

The purpose of a sanitary sewer smoke test is to identify leaks, breaks, or faulty connections in the system. Finding and sealing such leaks will help minimize the amount of inflow and infiltration (I/I) entering the system, reducing the risk of sanitary sewer overflows and backups into homes and residences.

A smoke test is planned to be performed on the sanitary sewer system for the Inflow & Infiltration Pilot Study. The study area is N. 28th St. to N. 31st St. from Holdrege St. to Potter St.

The smoke test is tentatively scheduled for September 15, 2017, but is dependent on the weather.

Electronic road signs will be posted in the days leading up to and the day of the test.

How Does it Work?

Harmless smoke will be blown into the sanitary sewer system through a manhole on the street. The smoke will fill the pipes, and if there is a leak in the pipe, it will exit the pipe and rise to the ground surface.

During the test, the project team will be looking for smoke coming from along the sewer alignment, manhole covers, roof vents, catch basins, downspouts, etc.

The smoke should not enter your home or business if it is properly plumbed, vented, and the water traps contain water. If smoke does enter a home or building, it will clear within 30 minutes with proper ventilation.

The Smoke is Harmless.

The smoke used in the test is:

  • nontoxic.
  • non-staining.
  • odorless.
  • harmless to human, pets, plants, and food.
  • not a fire hazard.

While the smoke is nontoxic and harmless, the smoke may be an irritant to people or pets with respiratory conditions. It is recommended that those with such conditions stay away during testing.

Preparing for the Test

The best thing you can to do prepare for the smoke test is be aware, which will help minimize unnecessary emergency calls. The testing should not affect your home or business, or your sanitary sewer service.

Sewer smoke testing in De Soto, Missouri

Smoke could enter your home or business through floor drains or plumbing fixtures (toilets, sinks, showers, etc.) if the water trap has dried up. To prevent this, pour a bucket of water down all floor drains and any plumbing fixtures that have not been used in the past month.

You need not need to be present during the testing. However, if you are home and you see smoke in your property, please notify one of the project team members who will be in your area conducting the smoke testing.
