Replacing a regional water system’s treatment plant
Fiveash opened in 1953. Its replacement had to be built at another site because water service needed to continue and the existing property lacked room for the new plant. [4]
Prospect Lake produces treated water that travels to Fiveash for storage and distribution. The City began the phased transition in September 2026, with Fiveash taking on its new role as the treatment system changes over. [1] [4]
Treatment and resilience
The plant treats groundwater from the Biscayne Aquifer using nanofiltration and ion exchange. Its design also includes pressurized multimedia filters and stripping towers. [3]
Kiewit serves as design-builder and engineer of record. Its delivery approach brings design and construction planning together, with a facility engineered for Category 5 hurricane-force winds. [2]
