Smoke testing now under way

As part of the Water and Sewer Services Department’s comprehensive maintenance program, crews have begun smoke testing of sanitary sewer lines in the Brush Creek Wastewater Treatment Plant collection system. Smoke testing helps the City determine points where, during rain events, extra water can enter the system. Testing is expected to continue through the end of the year.

Crews will be in the areas of:

  • Buffalo Road
  • South Roan Street from Mayflower Road to Plymouth Road
  • Plymouth Road
  • Swadley Road
  • Milligan Highway from Woodland Drive to Hiwassee Heights Drive
  • Cedar Grove Road
  • Lauderdale Lane
  • Other areas as shown on the attached map


Smoke testing is expected to continue through the end of December.

During the test, City crews will send white smoke designed for this type of testing into the sanitary sewer system by blowing it into a manhole. It is then forced out through lines and cracks, openings, or plumbing vents on or near roof tops. The smoke is safe, odorless, non-toxic and non-staining.

Testing can provide a service to homeowners. If home plumbing systems are correctly installed and well vented with working water traps, smoke should not enter the home. If smoke enters your home, there are deficiencies in your plumbing system. Please call 461-1646 for more information.
