Alta Sierra Reservoir Replacement

Replacing a Hypalon-Lined Reservoir with a Pre-Stressed Concrete Tank

The Nevada Irrigation District selected the Gateway Pacific Contractors/Bennett Engineering Services design-build team to construct a 3-million-gallon water storage tank to replace the District’s existing Hypalon-lined and covered reservoir.

The new tank is an AWWA D110 Type I pre-stressed concrete tank with a concrete roof designed to withstand local snow loads. The design also includes yard piping, additional drainage improvements, mixers and blowers with sound attenuation, and electrical and SCADA system upgrades.

Maintaining the existing berm, adding landscape screening, and new fencing and gate will minimize visual effects to the adjacent neighborhood. Construction included demolition and removal of the existing Hypalon liner and cover and replacement of the District’s existing water valves.  Construction is expected to be complete in early 2023.
