We’re proud to share that Georgetown Wet Weather Treatment Station has received an American Architecture Award, presented by The Chicago Athenaeum: Museum of Architecture and Design. The award recognizes the project’s innovative approach to civic infrastructure, demonstrating how essential public utilities can contribute to ecological health, neighborhood identity, and public understanding of environmental systems.

Designed for King County’s Wastewater Treatment Division, the facility treats up to 70 million gallons of combined sewage and stormwater per day during major storm events, helping protect the Duwamish River. Berger Partnership’s landscape design integrates green stormwater infrastructure, including vegetated roofs, permeable paving, bioretention planters, and rainwater collection systems. At the river’s edge, restored mudflat, marsh, and riparian habitats support shoreline stabilization and ecological recovery.

Working alongside Signal Architecture + Research, The Miller Hull Partnership, and the broader project team, Berger helped transform a complex industrial facility into a visible expression of environmental stewardship, connecting essential infrastructure to the community it serves.

We’re grateful to King County, our collaborators, and the entire project team for their partnership, and to The Chicago Athenaeum for this recognition.
