The University of California, San Diego is located in the La Jolla area of San Diego. With an enrollment of over 30,000 students and a main campus extending to 1,150 acres, the university is a prominent part of San Diego’s community and economy. Established in 1960, the university’s facilities now include over 760 buildings and nearly 900 acres of natural reserves.
As a public research university, UC San Diego is keenly aware of California’s ongoing water shortage and has embarked on a plan to leverage the availability of reclaimed wastewater in the San Diego area to further reduce the reliance on imported water in San Diego County. When planning its reclaimed water project, the university relied on its prior use of horizontal directional drilling with Fusible PVC® pipe to design an extensive distribution network with minimal campus and environmental disturbance. The project not only provides reclaimed water for irrigation systems that maintain the beautiful landscape, but also supplies water for the campus cooling tower complex, significantly reducing the potable water load.
Titled the “Reclaimed Water Pipeline Expansion,” the project included 4,800 feet of 12-inch Fusible PVC® pipe in eight different horizontal directional drills (HDD) through the heart of the campus. HDD installation protected the natural environment of the campus and minimized both vehicle and pedestrian disruption. Several of the directional drill pullbacks were completed at night and on weekends to minimize impact. Construction costs were also minimized by crossing underneath many of the existing utilities and roadways throughout the campus.
The project’s engineer, Greg Kump of Nasland Engineering, noted: “Underground Solutions continues to bring added value to our projects throughout San Diego County. They provide technical assistance during design, supportive guidance to bidding contractors, and cooperative, professional teamwork on the jobsite. Their project design and construction support is unique as a pipe supplier.”
Brian Jennette of NEWest Construction commented: “We’ve completed several projects with Underground Solutions and consider them an important partner. They always come through for us to help create a pipeline project that is constructible and cost-effective. Their field staff people are knowledgeable and reliable.”
Victor Cuen, owner of Riverside Directional Drilling, which completed the HDD work, said: “The Fusible PVC® pipe pulled very well through tough ground conditions. We encountered hard sandstone and pockets of cobble. Pipe staging and intermediate fusions were challenging at times on the busy campus. Underground Solutions worked very well with us to get all eight bores in the ground.”
