Headworks Replacement Project for 2020

Rendering of the new Headworks Building

Continuing the upgrade or the wastewater plant, this phase provides preliminary treatment by removing screenings and grit, and pumping the wastewater to the remaining treatment processes.  Additionally, the upgrade will allow the plant to hydraulically accept peak flows through the headworks and replace equipment that is at or near the end of its life expectancy.  The existing headworks is limited to a peak flow of 2.3 million gallons per day (MGD) with flows in excess of this being diverted to primary only treatment tank.  This phase and the next phase will allow the plant to accept and treat all incoming wastewater to secondary treatment levels.  These are the major components in this phase:

  • New headworks building
  • Screening equipment,
  • Grit removal,
  • Influent pumps,
  • Waste sludge pumps and,
  • Integrated SCADA controls,
  • New disinfection pumps and analyzers

The project is expected to be bid in November of this year and construction is expected to take 2 years.  The expected cost of construction is $6,500,000 to $7,500,000.
