With the completion of the Olmsted Hydroelectric Power Plant Replacement Project and the beginning of the North Fork Siphon Replacement Project, our infrastructure rehabilitation goals continue to be met. With the progress on the Utah Lake System Spanish Fork-Santaquin Pipeline and the procurement of lands for a future treatment plant in south Utah County, our vision for future population growth continues to be maintained. And with major forest fires ravaging our watersheds, our operational mettle continues to be tested and to be found extraordinary. Again, to all involved, thank you for your every effort. It is you that makes the Central Utah Water Conservancy District the respected and trusted organization that it is today. Gene Shawcroft, P.E.

This property, with its office complex and gardens, has come to symbolize the success of its staff and governing board throughout the development and construction of the Central Utah Project and related water treatment facilities. A new headquarters complex, located near the mouth of Provo Canyon, offers the advantages of both centralization and consolidation: Centralization among other District facilities including the Don A. Christiansen Regional Water Treatment Plant and the Olmsted 1 Hydroelectric Power Plant. Consolidation of multiple District operations and responsibilities into one campus. The new complex allows for growth over the next 50 years and is also easily accessed by all other District field offices and 2 treatment plants. 2018 Annual Report | Central Utah Water Conservancy District 3 Utah Lake System (ULS) The District continued construction on the first reach of the Spanish Fork-Santaquin Pipeline in 2018. The first reach and the flow control structure were constructed by Condie Construction. Substantial completion of that pipeline reach occurred in November 2018. W.W. Clyde began construction on the second reach in fall 2018. The expected completion date for this reach is July 2019. The District plans to bid and award the next reaches in the spring and fall of 2019. The District also completed the Diamond Fork Flow Study in cooperation with the U.S. Department of the Interior, the Utah Reclamation Mitigation and Conservation Commission (URMCC), and Utah State University. This study looked at the flow regimes which would be most beneficial for the fisheries in Diamond Fork Canyon. The results of the study will have implications on how the District operates the Sixth Water Flow Control Structure and the Strawberry Tunnel. 4 2018 Annual Report | Central Utah Water Conservancy District 2018 Annual Report | Central Utah Water Conservancy District 5 Central Water Project (CWP) CWP had another busy year in 2018. Construction of the Vineyard Wellfield Collector Pipeline Project, which consists of 3 miles of pipelines ranging from 24-inch to 48-inch pipe, began in March 2018. By the end of December, the general contractor (Whitaker Construction Company) had completed laying 75% of the pipeline. It is projected that the project will be completed in the beginning of May 2019 and will be ready to receive water from the wells once the well pump houses are finished. Well pump houses 14 and 15 were completed. Well 14 was put online and helped fill the demands of the CWP system during summer 2018. Well 15 was still in the process of being developed and cleaned prior to being put into service. Wells 8, 9, and 10, all 24-inch diameter wells, were drilled at the south end of the Vineyard Wellfield Collector Pipeline. Well 8 was drilled to a depth of 1,500 feet, and well development has been completed. It is ready to move forward with pump house construction in 2019. Well 9 was drilled to 1,200 ft and is currently undergoing well development. Well 10 was drilled to 1,300 ft and will continue with well development once development on Well 9 is completed. 6 2018 Annual Report | Central Utah Water Conservancy District Two new well pump houses were put online in 2018 and the wells helped fulfill the contractual obligations of the CWP system. Well 13 won the “Best Tasting Ground Water” and the “Best Tasting Water Overall” awards at the Intermountain Section Conference of AWWA in October 2018. This represents the third CWP well to win these awards. Contract water deliveries will continue to increase in the coming year. Jordan Valley Water Conservancy District, Pacificorp, and Lehi will all reach their maximum contract amounts. Saratoga Springs and Eagle Mountain will all be increasing their contracted amounts substantially. The CWP System will also continue to deliver increasing amounts to Vineyard. 2018 Central Water Project Deliveries Customer Agency Water Deliveries (acre-feet) Vineyard Town 367 Vineyard Town Non-CWP 0 PacifiCorp 1,694 Lehi City 615 Saratoga Springs 149 Eagle Mountain City 1,278 Alpine School District 21 Jordan Valley Water Conservancy District 10,896 Jordan Valley Water Conservancy District Non-CWP 1,618 CWP Use 7 Total CWP Contract Water 15,019 Total Non-CWP Contract Water 1,618 Total CWP System Deliveries 16,637 Sources CWP Well 11 3,116 CWP Well 12 1,043 CWP Well 13 2,617 CWP Well 14 267 CWP Well 15 0 DACRWTP 9,603 2018 Annual Report | Central Utah Water Conservancy District 7 Central Utah Project Operations The District operates, maintains, and manages the federally-owned Central Utah Project. Staff manages the CUP water supply and operates both project and non-project facilities each year to divert, collect, store, and deliver more than 360,000 acre-feet of water to meet project purposes. Major project purposes include providing supplemental irrigation water for agriculture, providing municipal and industrial water to approximately 1.2 million of Utah’s residents, providing environmental stream flows to sustain sporting and endangered species, and providing recreational opportunities on multiple waterways and waterbodies. Staff operates, maintains, repairs, and replaces many facilities, including 9 major dams and reservoirs, over 100 miles of large-diameter tunnels and pipelines, 9 diversion dams, 2 hydroelectric power plants, numerous flow-control and conveyance facilities, and a wide-area communication and SCADA system. Summer 2018 saw the beginning of the North Fork Siphon Replacement Project. This project includes building a new 84-inch pipeline parallel to the existing, still-operational facility. The project is expected to be completed fall 2020. 8 2018 Annual Report | Central Utah Water Conservancy District 2018 Annual Report | Central Utah Water Conservancy District 9 District Facilities All three of Central Utah Water’s treatment plants met their water quality goals in 2018. The Ashley Valley Water Treatment Plant (AVWTP) set a new plant production record by delivering 4,234 acre-feet of drinking water. The plant also met all other operational goals while experiencing unique water quality challenges resulting from severe drought conditions. The Duchesne Valley Water Treatment Plant (DVWTP) also met all operational goals while delivering a near-record production of 4,433 acre-feet of finished drinking water. Severe thunderstorms following a major wildfire in the watershed significantly impacted the source water quality to the plant, but plant staff worked around-the-clock to ensure continued delivery of exceptionally high-quality drinking water. The Don A. Christiansen Regional Water Treatment Plant (DACRWTP) delivered a record 32,267 acre-feet of finished drinking water to customer agencies. The treatment plant staff are recognized nationally for their ability to continue optimized operations and meet the very stringent water quality goals of the Partnership for Safe Water Program. The plant recently completed 15 years of optimized operations meeting highest-level (Phase IV) requirements. The plant and staff will be recognized at the Annual American Water Works Association Conference in June 2019, as one of only two plants in the nation to achieve this level of plant operations and water quality. 10 2018 Annual Report | Central Utah Water Conservancy District 2018 Annual Report | Central Utah Water Conservancy District 11 Water Quality 2018 was one of the worst wildfire years in Utah’s history. Several wildfires had negative water-quality impacts affecting District water treatment plants. The Dollar Ridge Fire burned approximately 70,000 acres of the Strawberry River watershed between Strawberry Reservoir and Starvation Reservoir. Much of the burned terrain was very steep and produced extreme erosion events when summer thunderstorms came in July and August.
