Inspections of the city’s sewer lines will start Monday, March 23.
The Oak Ridge Public Works Department will use a state-of-the-art system that employs a sonar machine that emits a repeating series of tones, similar to a musical scale. In open areas, the sounds can be heard over long distances, a press release said.
“The tones emitted by the machine, while harmless, are low enough in frequency that residents nearby may be able to feel and, in some instances, hear them,” the release said.
The testing that starts Monday is expected to last for eight to nine weeks, depending upon the weather and other factors, the release said.
When crews are working in neighborhoods, signs will be posted on main roads that announce “Acoustic Sewer Inspection in Area.”
