Authorized under the Central Utah Completion Act, the Diamond Fork System will contribute to the transbasin diversion of water from Strawberry Reservoir in the Uintah Basin to Utah's Great Basin. This water will be used not only for municipal and industrial purposes, but also for the Spanish Fork -Nephi Irrigation System. Boyle was selected by the Central Utah Water Conservancy District to provide preliminary and final design and plans and specifications for the 96 -inch diameter Diamond Fork Pipeline. Boyle engineers reviewed preliminary designs prepared by the U.S. Bureau of Reclamation, analyzed alternate pipe alignments based on both cost and constructability, compiled Preliminary and Final Design Reports, and completed the final design of seven miles of 96 -inch diameter steel pipe. Commencing at the proposed Monks Hollow Dam five miles up Diamond Fork Canyon, the pipeline traverses the canyon for approximately 37,000 feet to the mouth of the canyon. There it connects with the Spanish Fork /Nephi (SFN) pipeline which conveys water down Spanish Fork Canyon and south to Nephi for distribution to various irrigation companies. The 510 cfs Diamond Fork Pipeline will also enhance the Diamond Fork fisheries by limiting further erosion of the valley during high water flows. The project also included the planning and design of improvements to 7.5 miles of two -lane paved roadway through Diamond Fork Canyon. Boyle also provided construction phase services, including shop- drawing review and construction document interpretation. NOVLE
