Cycle the Well Field

May 16, 2014

On May 31, grab your bike, friends, and family, and head out for a free, guided riding tour of the Columbia South Shore Well Field

Join staff from the Portland Water Bureau and the Columbia Slough Watershed Council for a slow-to-moderately paced 16 mile ride. On the tour, you’ll coast through the beautiful, flat terrain and learn all about the safety, hydrology, and history of Portland’s underground drinking water system.  

The Columbia South Shore Well Field is used as backup for the Bull Run Reservoirs, and can produce nearly 100 million gallons of water per day.  During the summer months, when the demand for water is higher, the well field provides an additional source for our community’s water needs.

Thanks to this great groundwater source, the incredible Bull Run can be maintained as an unfiltered water system – providing Portland with some of the best drinking water in the country.

Check out PWB's website to learn more about the Columbia South Shore Well Field.

Along with your bike, don’t forget to bring your helmet, a water bottle, and lunch. Hope for sun, but just in case check the weather and dress accordingly!

The ride is suitable for beginners to advanced cyclist, but recommended for riders ages 12 and up.

To register for the tour, visit the Columbia Slough Watershed Council’s website.
