Resting at the confluence of the Willamette and Clackamas Rivers, the Tri-City Water Pollution Control Plant expansion project is the first phase of a planned expansion of the plant. Serving 64,000 people, the project allows the plant’s capacity to grow from 8MGD of wastewater to 40MGD by 2060.
Our design work on this first phase addressed the process buildings to provide wastewater treatment via membrane filtration technology and UV disinfection. The facilities include an 8,540 sf Fine Screens Building, 4,013 sf UV and Chemical Building, 2,676 sf Substation and Electrical Building, and a 12,833 sf Membrane Building — all connected via a 21,180 sf underground utilidor.
This project was a true collaboration with the water engineers to design an expandable, sustainable, enduring, and valued public asset.
