Polson Water Resource Recovery Facility Project

**Monthly project reports can be found below**

Project Description:

The project construction of a new mechanical wastewater treatment facility including rotary drum fine screens, vortex grit removal and grit washing equipment, sequencing batch reactors (SBRs), post equalization storage, ultraviolet disinfection, aerobic digesters, provisions for sludge dewatering with geotextile dewatering bags, scum lift station, site lift station, and all associated site civil, structural, electrical, and building systems. Project also includes the headworks building, a UV disinfection building and a control building with laboratory, office, process blower equipment room, chemical storage area, and basement with solids processing pumps and mechanical equipment.

The new rotary drum screens, vortex grit chamber equipment, grit washing systems and the SBR treatment equipment will include installation and commissioning only of this equipment pre-procured by the City of Polson. The project also includes draining the existing lagoons, removal of existing aeration equipment and buried process piping, and lowering of the existing earthen lagoon dikes to the sludge layer to allow drying and subsequent land application by others outside of this contract. The overall SCADA system integration will also be completed outside of this contract by the City’s systems integrator.
