Clallam County PUD Holgerson Well Generator
Adhering to residential noise ordinances
Extensive CAD design
Clallam County Water District entrusted Casne Engineering to design a solution for installing a stationary generator at the Holgerson Well pump station, ensuring reliable standby power. The project had to consider noise levels, as the pump station is in a residential area. Without any available drawings, Casne's design team produced CAD plan views of the building and property, electrical one-lines, layouts, and an equipment inventory.
The most substantial load was a 60 HP submersible pump situated roughly 180 feet below grade and connected to a VFD. Casne carried out load calculations, generator sizing, and an evaluation of the historical load data from the PUD. The final deliverable included a 70 KW LP-fueled generator enclosed in a sound-attenuated, outdoor enclosure. Additional components consisted of a 500-gallon LP fuel tank, reinforced concrete equipment pads, and protective bollards.
The design involved reworking the existing utility service, adding a site grounding plan, and offering options for manual and automatic transfer switches, each rated for service entrance.
