CWS Durham Facility (Tigard) Tours 2026

Ever wonder what happens to the water you send down the drain from the sink, toilet and shower? Get a firsthand look at our state-of-the-art, award-winning facilities that clean wastewater from homes and industry to nearly drinking water standards. The cleaned water is released into the Tualatin River and is so clean, it actually improves river health. If you'd like to see this amazing process, join us on a free tour.

Tours are on foot and cover uneven surfaces, stairs, and tunnels. Be prepared to walk one mile and wear closed-toe shoes. Dress for the weather. Tours are appropriate for children 8 years and older with an adult.
