== Abstract ==

Polyurethanes have found extensive applications in the pipe coating industry because they exhibit excellent corrosion resistance, abrasion resistance, toughness, and chemical resistance, as well as a wide range of useful mechanical properties. Though the first AWWA standard for polyurethane lining and coating of steel pipe was published in 1999, fast-setting, high-solids polyurethane has been used to line and coat steel pipe since the 1980’s. The Provo Reservoir Canal Enclosure Project (PRCEP) is a 21-mile, 126-inch diameter steel pipeline that was placed into service in early May 2012. This $150 million undertaking is saving approximately 8000 acre-ft of water annually from evaporation and seepage, and has the capacity to carry 400 MGD of raw water. Several pipe materials were considered for the construction of this line, with polyurethane lined and coated steel pipe being selected as the most economical solution for the project. The PRCEP line is one of the longest and largest-diameter polyurethane lined and coated steel water transmission pipelines in the world, and certainly the longest in North America. This paper systematically outlines the contents of the AWWA C222 standard for polyurethane coating systems and relates it to the project, in tandem with discussions on the requirements of the project specifications. In-plant coating application and quality control are discussed. Installation and constructability issues are discussed from the Contractor’s perspective.
