South Park wastewater backup protection
King County is working on short-term and long-term solutions to reduce the risk of wastewater backups in South Park.
Project description
King County Wastewater Treatment Division (WTD) is working in South Park to reduce the potential for wastewater backups in homes. These efforts are more important than ever because climate change is bringing weather extremes to the Pacific Northwest. As we have seen in recent years, big storms and high tides together can overwhelm public infrastructure and cause damage. We are updating and adapting our wastewater system to prepare for severe storms, higher tides, and sea level rise – all to better protect the South Park neighborhood. We are working closely with Seattle Public Utilities (SPU) to design and implement solutions, prevent wastewater backups and protect public health and the environment.
Project update
Spring 2024
- Homes that have reported sewer backups in the past now have protective equipment installed.
- We’ve made changes to our system to reduce the risk of backups.
- We’re looking at how to adapt our system to protect South Park from future sewer backups as high tides and storms get bigger.
Sometimes unexpected things happen. If you are experiencing a flood or sewer backup, please call the SPU 24/7 Operations Response Center at (206) 386-1800. SPU will coordinate with King County WTD on wastewater issues. For emergencies, always call 9-1-1.
