Salmon Creek WWTP Solids Handling Improvements, Southwest Suburban Sewer District



BHC designed a complete upgrade to the wastewater treatment plant electrical power distribution and control systems.  A new utility service, switchboards with zone selective interlocking, generator and transfer switches, motor control centers, low voltage transformers and panelboards were all replaced in the aging plant.  New PLC-based control panels replaced the existing obsolete control equipment.  BHC prepared detailed phasing plans for the replacement of the equipment while the plant was operating.  A new anaerobic digester, mixing system, solids handling building, and lab/office building were also added.


  • Increased plant reliability with electrical design without single points of failure
  • Detailed electrical construction phasing
  • Enhanced safety design to reduce arc flash hazards
