Nutrient Recovery Facility at the Rock Creek Advanced Wastewater Treatment Facility

Hillsboro, OR

MWA Architects designed this 4,728sf building for Clean Water Services at their Rock Creek Advanced Wastewater Treatment Facility to house the largest municipal nutrient recovery structure built to date.

Visible from an adjacent public park, this single-story 48ft tall building is designed to accommodate an innovative technology system that turns waste into a commercial product. Utilizing Ostara© technology, this new facility will recover 1,200 tons of phosphorous annually and transform it into fertilizer sold to commercial growers.

Design considerations included careful placement of buildings on site due to the structural requirements of the Ostara system and creating basement access to an utilidor. Accommodating trucks necessitated re-grading of portions of the site and removal of a restraining wall. Building forms and color respond to the existing plant structures and its proximity to a public park.
