The City of Grinnell Water Resource Recovery Facility uses an activated sludge and aerobic digestion treatment system. The treatment process uses four basic steps: Step 1 - Wastewater enters the headworks building where screenings and grit removal take place to remove any solid material. Step 2 - The water enters oxidation ditches where micro-organisms consume remaining organic material, the micro-organisms freely move around aided by paddles (activated sludge system). Step 3 - The water is sent through clarifiers where solids settle. Step 4 - The water goes into the UV building for disinfection before discharge into Sweetwater Creek.
