Seattle’s Georgetown Wet Weather Treatment Station Receives 2023 Award for Innovation & Achievement in Sustainability

The Georgetown Wet Weather Treatment Station earned the 2023 Award for Innovation & Achievement in Sustainability from the Northwest Construction Consumer Council. 

 The award recognizes excellence in the engineering, design and construction of projects complete or nearing completion during the prior two years. Winners can be a person, group of people, process or project that exemplifies outstanding contributions to sustainability and safety on capital construction projects.  

 The station can process up to 70 million gallons of stormwater and wastewater daily, preventing it from spilling into the Duwamish River and Puget Sound.  

During construction, many key sustainability features were considered, including: 

• Planning and designing for a changing climate 
• Diverting more than 85 percent of demolition materials from the landfill 
• Implementing a wide range of green infrastructure: permeable pavement, green roofs, roadside rain gardens and cisterns 
• Reducing chemical use at the facility 
• Restoring the shoreline along the Duwamish River 
• Supporting jobs through a local hire requirement 
• Using public art and green space to enhance a significant corner of Georgetown 
• Partnering with the local community in a Design Advisory Group that influenced the site’s look and feel 

Flatiron is proud to contribute to improving Seattle’s water quality through this project, which involves the collaboration of the King County Wastewater Treatment Division and the Georgetown community.
