Roseburg Urban Sanitary Authority crews will be conducting smoke tests to check for breaks and defects in the sewer system starting in a section of Roseburg on Monday and continuing through Friday.
The testing will be done in the area south of West Harvard Avenue from Fremont Middle School to Harrison Street to the east.
RUSA Engineer Tech Ryon Kershner said residents may see smoke coming from vent stacks on buildings during the testing.
“And that’s perfectly normal,” Kershner said. “But if it’s not as it should be, and we suspect it’s not, the smoke actually seeps up out of the ground.”
Kershner said the smoke is probably the most effective way to test a large area in a short amount of time.
But don’t be alarmed if you see smoke, he said. It has no odor, it’s nontoxic, nonstaining, does not create a fire hazard and will dissipate in a few minutes, according to Kershner.
If smoke enters a building, it probably means that there are defects in the plumbing that could allow dangerous sewer gas to escape, RUSA officials said.
If you notice smoke in your building, note the location of the smoke and call RUSA at 541-672-1551.
