Project Description:Indy-GBT-1.0
Commonwealth has performed the design and coordinated with the City's selected construction management team during construction of a multi-faceted improvements project at the Belmont Advanced Wastewater Treatment Facility.  These projects generally entail:

  • Six (6) New Gravity Belt Thickeners (GBTs), Required Modifications to Existing Facilities and Addition of Required Support Equipment
  • A New Primary Effluent Pump Station (PEPS)
  • Improvements to the Existing Headworks, Trash Racks and Grit Settling Tanks
  • A New Plant Drain Pump Station

The major components of the GBT project include two gravity sludge feed wells, four centrifugal pumps to feed sludge to the gravity belt thickeners, six gravity belt thickeners, a polymer feeding system, a non-potabIndy-GBT-2.0le water supply system, a filtrate storage system and an odor control system.


The PEPs component of the project at the Belmont Wastewater Treatment Plant (AWT) includes the construction of a new submersible pump station to transfer primary effluent from the Belmont AWT to the Southport AWT.  This station consists of three pumps.  The firm capacity of the pump station (with two of these pumps operating) is 30 MGD.  

The Headworks component of the project is generally "maintenance" in nature.  Miscellaneous repairs and replacement work has been designed and performed on the existing three (3) Infilco Degremont, Inc. climber screens (150 MGD rated capacity) and Grit Tanks / Equipment.

The Plant Drain Pump Station project at the Belmont Wastewater Treatment Plant (AWT) includes the construction of a new drain pump station consisting of one 20 mgd pump.  The pump is anticipated to be used only during wet weather flows when the screw pumps are highly utilized.
