Polson Water Resource Recovery Facility

This project consisted of designing a biological nutrient removal wastewater treatment plant to replace the City of Polson’s existing aerated lagoons.

The DOWL team evaluated several alternatives, including membrane bioreactors, conventional activated sludge, and a sequencing batch reactor (SBR). Ultimately, the project team and the client selected the SBR option for the final project and used a pre-procurement process  to select the headworks screens, grit removal equipment, and biological treatment equipment.

The final design included new dual fine screens, grit removal and washing, sequencing batch reactor, post equalization basin and outlet control valves, UV disinfection, aerobic digestion, and sludge dewatering facilities.

This project included planning, design, and construction of a new advanced wastewater treatment facility.
