Problem: The Davis Aqueduct in Utah has supported Davis County’s water supply since the 1950s, delivering water to hundreds of thousands of residents. Located along the Wasatch Fault, the aqueduct required a major resilience upgrade to protect service continuity during seismic events. Weber Basin Water Conservancy District needed a high-horsepower pump capable of handling sudden system pressure changes while avoiding traditional surge tanks, which add cost, space demands and long-term maintenance complexity. The solution also had to meet current demand and support future system expansion.
Solution: Trillium Flow Technologies supplied a 1,500 hp Floway vertical turbine pump as the centerpiece of the new pump station. The pump integrates a performance-engineered flywheel to provide surge control, eliminating the need for large surge tanks. Its vertical turbine design supports high-horsepower municipal applications while maintaining efficiency and reliability under seismic conditions. Engineered for continuous operation during seismic-related disturbances, the pump protects aqueduct integrity and water delivery. To support long-term growth, two additional Floway cans were installed for future pump additions, enabling scalability within the same resilient infrastructure footprint.
Result: The vertical turbine pump now anchors the Davis Aqueduct’s seismic resilience strategy. The system delivers reliable water service to approximately 650,000 residents with built-in surge protection and no surge tanks. The utility achieved reduced infrastructure footprint, optimized project cost and simplified construction, while securing future-ready capacity for both treated water and irrigation demand. 832-200-6220; www.trilliumflow.com
