Oracle Ridge Tailings Storage Facility Diversion Design & Construction Oversight
WET designed a ½-mile long clean-water diversion to route stormwater around a tailings storage facility in Arizona. The project was permitted through the Arizona Department of Environmental Quality during winter of 2022 and constructed later that spring. This structure is designed to withstand the 100-year storm.
We were able to complete this project under budget and on-time despite losing several weeks of construction due to wet and muddy conditions. Furthermore, the Contractor noticed a large elevation discrepancy between the theoretical existing ground and elevations that were measured with his machine control equipment. WET worked together with the Contractor and made some minor field design changes to accommodate the elevation bust.
Troublesome Creek Flume
WET was hired to install a 12-inch Parshall flume on a perennial mountain stream in Colorado. Design drawings and construction specifications were prepared and submitted to obtain county-level permits including a Floodplain permit and a No-Adverse Impact certification. WET personnel conducted a reach and cross-section survey and subsequent hydraulic analysis to support design and permitting efforts.
WET personnel installed the flume during the fall of 2024 after obtaining all necessary permits and easements. The Parshall flume has a stilling well instrumented with a shaft encoder that measures stage. The station has a hard-wired internet connection and pushes hourly data to the Colorado Division of Water Resources database.
