Smoke testing in the Flat Branch and County House Water Basin
COLUMBIA – Starting the week of June 20, the City of Columbia Utilities –Sanitary Sewer and TREKK Design Group will perform smoke testing of sewer lines in Flat Branch and County House Branch Water Basin.
The testing helps to locate sources of inflow and infiltration (I & I) of storm water and groundwater into sanitary sewer collection system. When water from different sources enters the sanitary sewer system, the system can cause sanitary sewer backups.
Although the smoke that will be used is non-toxic , harmless, has no odor and creates no fire hazards, residents of the affected area will be notified via door hanger on their front door. The door hangers will contain important information concerning the testing. There will also be signs in the neighborhood that identify which areas TREKK is conducting and performing the smoke testing.
During the testing, TREKK will identify defects that occur; such as, roof downspouts, uncapped clean outs driveway drains, stairwell drains, yard or area drains, window well drains, foundation-perimeter drains and defective service pipes.
The information that will be gathered through the smoke testing’s will be used to improve the sanitary sewer services to the affected neighborhood and the community.
The testing will last until the end of July.
