Smoke testing in the City of Richardson is taking place in the Rowlett Creek Basin starting on Tuesday, May 28, and is expected to last until early July, weather permitting.
Testing involves the use of a smoke generator to blow nontoxic smoke into manholes. The smoke travels through the sewer pipes and finds its way out, lightly billowing from the ground when cracks in the underground piping exist. The coordinates of damaged pipes are noted by technicians so they can be addressed in future projects.
Richardson began its multiyear, citywide examination of approximately 2.16 million linear feet of sewer pipe, or more than 400 miles of sewer line, in 2017. The final 140,500 linear feet of line are being tested this summer.
