On September 17, 2018 during the commencement of our pipeline assessment project a leak was detected and confirmed on a 12-inch water main running under the flood control channel located on Garfield Avenue. Upon discovery, Public Works explored several options to repair the leak. After careful consideration and thorough investigation, Public Works devised a plan to repair the leaking main with a cutting edge trench-less technology.

City crews were deployed to excavate “pits” to expose the water main on each side of the channel. Performance Pipeline Technologies performed a 2-3 pass cleaning of the pipeline and a CCTV inspection to confirm and document the exact leak location and the acceptability of the liner. On April 8, 2019, approximately 355’ of Primus Liner was installed. High-pressure fittings specifically designed for the liner were installed and used to terminate the ends. Over the course of the next couple of days, the liner was tested to ensure water quality standards and the integrity of the liner were in place. The liner was pressure tested to city standards and specifications to ensure proper installation and operation. Upon completion of the pressure test, the line was disinfected and bacteriological samples were taken and analyzed by a state certified laboratory to ensure water quality. The liner was then tied back into the existing water main and placed back into service. The “pits” were back-filled and the project was completed.

Completion of the project is essential to maintaining water quality in the area. Isolated water mains do not allow for water circulation redundancy. Such conditions cause water quality to degrade. In this case, Public Works was able to quickly place the water mains back into service to avoid compromising the quality of the City’s water and continue providing a safe, clean, and continuous water supply to our residents!
