Group Delta, an NV5 Company, provided a geotechnical and fault investigation for a replacement reservoir of the existing Oak Knoll Reservoir. The existing Reservoir is a 100+ year old concrete reservoir situated in an active fault zone. The planned improvements will replace the tank with newly constructed steel tanks. The purpose of the investigation was to mitigate fault the fault rupture hazard at the site with respect to the design, construction, and location of the new tanks. Other site improvements include new pipelines, valves, and other civil site improvements.
Value Added
- Enhanced Seismic Safety: Our team’s fault rupture hazard mitigation directly supports the safe design and placement of new steel tanks, ensuring long-term resilience in an active fault zone.
- Preservation of Critical Infrastructure: By replacing a 100+ year-old concrete reservoir, the project modernizes essential water storage infrastructure while addressing geotechnical vulnerabilities that could compromise service reliability.
- Comprehensive Site Support: In addition to fault investigation, our team’s involvement in evaluating conditions for new pipelines, valves, and civil improvements ensures cohesive and secure development across the entire site.
