Smoke testing of sewer lines for sanitary sewer evaluation
								
	(COLUMBIA, MO) - The city of Columbia recently retained the
services of TREKK Design Group LLC to assist in detecting sources of
inflow and infiltration into the sanitary sewer collection system. As
part of this study, TREKK will conduct smoke testing activities. Testing
is expected to begin the week of Oct. 27 and should take one to two
weeks, weather permitting. Testing will only be done within the
perimeter of West Boulevard, Broadway, McBaine and Worley streets. No
other parts of Columbia will be affected.
	The purpose of the tests is to locate defects in the sanitary
sewer collection system. The “smoke” that will be used for this
project is non-toxic, harmless, has no odor and creates no fire hazard.
During the testing activities, TREKK personnel will be identifying
defects that are revealed when smoke escapes through them. Locations for
defects may include roof downspouts, uncapped cleanouts, driveway
drains, stairwell drains, yard or area drains, window well drains,
foundation-perimeter drains and defective service pipes. 
	The information gained from these activities may be used to
improve the neighborhood’s sewer services. Questions regarding this
testing should be directed to the Public Works Department, Sanitary
Sewer Engineering, at (573) 874-7250.
