Abstract
Lack of knowledge about the performance of emerging sewer rehabilitation technologies represents a critical shortcoming in the water infrastructure industry. This has led the leading aging water infrastructure research organizations to develop pipe rehabilitation technology demonstration programs. Specific scenarios of interest include technologies applicable to challenging site conditions and pipes with challenging configurations. The results of these programs are intended to enhance the industry’s awareness of available technologies and their capabilities. This paper describes the demonstration of an emerging ultraviolet (UV)-cured, glass fiber–reinforced (GFR) cured-in-place pipe (CIPP) technology used to rehabilitate 271 m (888 ft) of 250-mm (10-in.) clay pipe in Frisco, Texas. This technology met the utility owner’s requirements, and mechanical testing showed that the liner exceeded the minimum design requirements. A key takeaway from this project was the importance of using the proper test method when evaluating the liner’s structural properties. These findings are valuable for water infrastructure system engineers in need of alternatives to traditionally disruptive pipeline renewal methods.
