Underground Solutions provides infrastructure technologies for water and sewer applications. UGSI's Fusible PVC® products contain a proprietary PVC formulation that, when combined with UGSI's patented fusion process, results in a monolithic, fully-restrained, gasket-free, leak-free piping system. Fusible C-900® and Fusible C-905® both comply with AWWA C900 and C905 respectively and are certified to NSF 61.
The City of San Clemente, California has long been considered a gem on the Southern California coastline. The 18 square mile area located on the southern border of Orange County is home to 55,000 residents. The City is committed to responsible use of available water resources to sustain the lifestyle of the community and it continues to expand a robust recycled water distribution system. The City operates a 2.2 million gallon-per-day water reclamation plant for tertiary treatment in accordance with California’s Title 22 program. As with most recycled water projects, the most significant challenge is economical distribution of the product water for beneficial use.
Thinking creatively, the City saw an opportunity to convey recycled water utilizing 16-inch Fusible PVC® pipe slipped into an abandoned cement pipe with a 20-inch inside diameter. This trenchless installation of more than 2,000 feet of fused 16-inch PVC pipe greatly reduced the cost of conveyance since excavation and the associated traffic control was limited. Additionally, the high-strength properties of the Fusible PVC® pipe allowed for the largest possible inside diameter, yielding the maximum carrying capacity for the completed line.
The pull-in operation was completed using a cable winch, with all 2,026 LF pulled into the host pipe during one shift. Connections to the existing system were accomplished with standard ductile iron fittings. Contractor Don Colich said: "We were very happy with the Fusible PVC® product. It worked very well for us on this job. Underground Solutions gave us great support and we worked as a team to complete a very successful project."
