The Oak Ridge Public Works Department continues to use state-of-the-art technology to perform inspections of the city’s sewer system, a press release said.
This technology employs a sonar machine that emits a repeating series of tones, similar to a musical scale. In open areas, it can be heard over long distances. While harmless, the tones emitted by the machine are low enough in frequency that residents nearby may be able to feel and, in some instances, hear them.
Testing is ongoing, but it will be concentrated to certain areas depending upon weather constraints and other factors during the week of December 7. This includes the area in and around Emory Valley Road, Briarcliff Avenue, and Rivers Run subdivision.
Residents will notice signs posted on main roads stating, “Acoustic Sewer Inspection in Area” while crews are working in their neighborhoods.
Questions can be directed to the Public Works information line at (865) 425-3619 or by email [email protected].
