Smoke testing of sewer lines for sanitary sewer evaluation rescheduled
								
	(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 take place Monday and Tuesday, Nov.
24-25, then resume Dec. 1 and continue for approximately 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 test is to locate defects in the sanitary
sewer collection system. The “smoke” that will be used is non-toxic,
harmless, has no odor and creates no fire hazard. During testing
activities, TREKK personnel will identify defects 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 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.
