"Together we are creating a legacy for our communities and region."

Diane Taniguchi-Dennis, Deputy General Manager, 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.

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.

Fernhill Natural Treatment System (NTS) creates an ecological bridge between treatment and the watershed, where water is cleansed further, cooled and naturalized before its return to the river.
