The City of Oak Ridge will be utilizing new technology to perform inspections of the City’s sewer system. This technology employs a sonar machine that emits a repeating series of tones similar to a musical scale and in open areas can be heard over long distances.  The tones emitted by the machine, while harmless, are low enough in frequency that residents nearby may be able to feel them.

Residents will notice signage posted on main roads saying “Acoustic Sewer Inspection in Area” when crews are working in their neighborhoods.

Questions or comments can be directed to the City of Oak Ridge, Public Works Department at (865)425-1875.  More specific information may also be located at
