Snohomish Wastewater Treatment Plant Standby Power, City of Snohomish

Snohomish
Washington

About

At the wastewater treatment plant, BHC designed the addition of a 275kW diesel generator, 600A service-entrance rated automatic transfer switch and controls upgrades to provide 100% standby power for the treatment plant.  The generator was located on a raised foundation to keep it above the 100-yr flood plain.  Surge protection systems were added at both the north and south utility services and other locations to protect vital equipment.  The generator was sized to accommodate the existing plus planned future loads.  Control system upgrades were completed at the same time.

Features:

  • 275 kW backup engine generator
  • 600 amp ATS
  • Control system upgrades
