Clarksville officials say no drinking water contaminated following sewer line failure

City spokesperson Richard Stevens said in a release that Clarkville Gas & Water (CGW) crews worked for 21 hours Sunday and Monday to repair the 12-inch sewer main line that failed near the intersection of Trenton Road and Stillwood Drive.
As required by the Tennessee Department of Environment and Conservation (TDEC), signs will be posted on a nearby creek to meet public notification requirements and a sewer overflow report has been submitted as required.
Stevens said the break was 18-feet deep and under a large entrance wall for the Timber Springs subdivision.
A 6-inch high-pressure gas main, a 2-inch gas main and a 12-inch water main all were in the same area, and care had to be taken during excavation to minimize potential damage to other utilities, CGW officials said.
A gas-leak technician arrived at 1:47 a.m., diagnosed the sewer problem and called in a sewer crew to investigate.
The water/wastewater supervisor was on the scene at 2:47 a.m. Sunday and the Wastewater Collections System Manager and a sewer construction crew mobilized and responded at about 3 a.m. to begin repairs in accordance CGW Sewer Overflow Response Plan.
An emergency locate for underground utility lines was called in to Tennessee 811.
During excavation, the crew damaged and repaired a 2-inch gas main that was not mapped.
The wall and some trees had to be demolished in order to access the sewer main below it.
“Seven crew members responded and were on the clock by 3 a.m. Sunday.
