If you see white smoke coming from the plumbing inside your home this week, don't panic.
You might, however, want to call a plumber.
The city's public works department will conduct a smoke test Thursday and Friday on all sewer lines between the railroad tracks on North Main Street and Broadway.
The test will be from 9 a.m. until 4 p.m. both days.
Larry Hazlett, director of public works, said the sewer lines in that area will be filled with fast-clearing harmless white smoke to help locate groundwater infiltration or damaged sewer lines.
