[ARCHIVED] Sewer line smoke testing planned for preventative maintenance

Clarksville Gas and Water

CLARKSVILLE, Tenn. – Clarksville Gas & Water will conduct sewer line smoke testing on Wednesday and Thursday, June 16-17, in extensive areas around the Madison Street Historic District, Porter’s Bluff Road, Greenwood Avenue, Talley Drive, Pageant Lane, Golf Club Lane, Gracey Avenue, Woodward Street, Paradise Hill Road and Daniel Street. 

A full list is available on the Gas & Water website at

Smoke testing is a cost-effective preventative maintenance method of introducing a safe, non-toxic smoke with air pressure into the City’s wastewater collection system. Smoke travels through the system and exits through cracks or weak places in sewer lines.  Visually spotting the smoke at the exit point helps utility crews locate and identify possible defects for further examination. 

A camera is then introduced into the pipe to video a trouble area. Once assessed, repairs can be made at the point of the defective pipe without excavating large areas of property or several feet of sewer pipe if it’s not necessary.

Smoke testing signs will be posted in affected neighborhoods and residents should not be alarmed if they see smoke rising from manholes or sewer line right-of-ways during testing. 

If smoke is noticed in or around homes or businesses, please contact the on-site testing crews or call the Sewer Construction office at (931) 553-2424 during normal business hours, 8 a.m.-4:30 p.m., Monday-Friday. More information about smoke testing is also available on the Gas & Water website,
