Workers will be releasing smoke into sewer lines throughout the city to detect if there are any breaks or defects in the system, according to a release from the city. Testing will begin on the east side of Franklin Road near Moore's Lane.
“Over the past few years, we have relied on visual or remote camera inspections to assess the conditions of our sewer pipelines," said Drew Muirhead, the assistant director of Brentwood Water Services, in a release. "Smoke testing is another tool we will use to identify defects, which allow groundwater and rainwater to enter the sewer piping system.”
Testing will begin Sept. 21 and is expected to continue over the next three to four weeks, according to the city.
The smoke is nontoxic and approved for use by the Environmental Protection Agency, according to the city. While the smoke should not enter homes, if residents see it in their home during the testing period, it could be a sign there is a plumbing issue.
The city will notify residents near where testing will occur and will leave door hangers before testing on a street.
The city is asking residents to take steps to ensure smoke does not enter their homes, which will be outlined in the testing notice.
