Oak Ridge North City Council members approved a $45,242 expense Aug. 12 following Southern Montgomery County Municipal Utility District's discovery of a sinkhole that caused significant damage to the main sewer line for the city.

What’s happening

Kim Wright, general manager of SMC MUD, presented the issue during the council meeting Aug. 12, saying the sinkhole caused a need for “emergency repairs” to prevent a loss in service.

“There was about 20 linear feet of ductile iron pipe, and a manhole where we had a pretty significant sinkhole that was identified,” Wright said.

Wright said the emergency repair cost around $34,000, but further damage was found which will require additional projects to prevent more emergency repairs.


“We have some significant deterioration in this area, and so we have defined a project for this next fiscal year to start addressing this area,” Wright said. “It's approximately just over 1,700 linear feet of ductile iron pipe in this area, and about 14 manholes that we're looking at rehabbing.”

What’s next?

The funding approved by council will go toward a $138,920 engineering study performed on behalf of SMC MUD to determine the best course of action for repairs.

Wright said she will come back before the city once a construction bid is complete to provide the city’s expenses for the actual reconstruction of the pipeline, which will be shared with the other municipalities which are serviced by SMC MUD. Wright said the total construction estimate is roughly $828,000.


Council approved the expense and requested the additional information regarding the city’s share to be presented at a future meeting.
