The City of Huntsville Wastewater Division will be conducting a sewer survey between 8 and 11 a.m. Friday, August 10, east of Sycamore Avenue. The affected area will include sewer right-of-way running north and south between Oak Lawn Street and Bearkat Boulevard. The survey should take less than three hours to complete.

Residents and businesses in the surrounding areas should be aware that smoke will be pumped into the sewer system. Smoke may be seen blowing out of roof vents, sewer manhole covers, open or defective cleanouts, and drainage ditches.

The smoke is non-toxic and will completely disperse within minutes of testing.

To avoid having smoke enter a home during the test, residents should make sure all appliance hook-ups are fitted and that plumbing is working properly. If smoke is detected coming from a toilet, sink, or washroom, call a plumber and the City immediately.
