"Together we are creating a legacy for our communities and region."
Diane Taniguchi-Dennis, CEO, Clean Water Services
Fernhill is part of more than 700 acres in Forest Grove owned by Clean Water Services for water resources management. Fernhill utilizes natural treatment systems, or wetlands, to improve water quality by removing nutrients, cooling, and naturalizing the water after conventional treatment. Fernhill is designated an Important Bird Area and is also home to beavers, frogs, coyote and other wildlife.
Fernhill Innovations featured at Water Conference
Fernhill’s Nutrient Filter (also known as the Vertical Flow Wetlands) and Floating Islands were featured in Clean Water Services’ innovation showcase at the Water Environment Federation’s Technical Exhibition and Conference in New Orleans this year. Check out the innovations we are investing in.
It turns out, people are interested in knowing more about what happens after they flush the toilet. Read about how water treatment facilities, including Fernhill, are drawing the community into their world by building parks, hiking trails and attractive spaces.

nutrient filter testing
North of the Fernhill shelter, about two acres of vertical flow, rock filter were recently constructed. The filter system was built on top of an asphalt liner and uses rocks to support organisms that remove pollutants from water. This type of filtration is another innovation in water treatment that is quite different from the 90-acre natural treatment wetlands to the south, that uses a diversity of native plants to filter water. Currently the filter is being tested and visitors may see water flowing in different sections of the filter. Once testing and alterations are complete, the surrounding area will be landscaped with native plants. A new ADA accessible trail will circle the new facility.
