The Weber Basin Water Conservancy District's (WBWCD) aqueduct system was riddled with leaks throughout its 48 and 60-inch joints. WBWCD contracted Carollo Engineers to assist with a condition assessment of the aqueducts. Upon completion, Carollo determined that the best solution would be an epoxy product that was environmentally safe as well as safe for use in drinking water. As a result, A&W Coatings, along with Warren Environmental's 301-01 epoxy specialized for potable water use, was awarded the project. Over two weeks, the A&W crew sealed over 350 joints.
Four years after completion, Carollo and WBWCD performed an inspection of the Weber Basin pipe system. Of the 350 sealed joints, only one 60-inch joint had significant damage in need of repair. This was due to the ground around the joint caving in and the joint itself getting filled with weak materials before A&W worked on the original project. The A&W team filled the joint with Warren's mastic and embedded the coating with E-Glass fiber mesh to ensure the structure's longevity. The other inspected joints were in great condition and it was noted that there was an increase in flow rate throughout the entire system since being lined with Warren's epoxy.
