Fyfe - Drinking Water Reservoir Seismic Rehabilitation

Ensuring seismic resilience in high-risk zones is a critical priority for municipal water storage, particularly for dual-purpose structures that serve both as utility assets and community recreational spaces. When a large in-ground reservoir required upgrading, engineers faced the challenge of adding significant structural strength without increasing the dead load on the existing slab. Traditional retrofit methods would have necessitated extensive foundation work to support the added weight, driving up costs and project duration.

Advanced fiber-reinforced polymer (FRP) systems provided a lightweight, high-performance solution that enhanced structural integrity without the burden of extra mass. These NSF-certified carbon fiber wraps allow for a flexible installation schedule, accommodating seasonal water demands and fluctuating weather conditions. By applying the material in a specialized crisscrossing pattern on both the deck and soffit, the reservoir gained the necessary resilience to withstand future seismic events while maintaining its secondary use as a recreational area. This approach streamlined the rehabilitation process, proving that composite technology can offer superior performance and cost savings in complex urban environments.
