Water Repair

Visit our water outage map and find out how you can prepare for a planned water outage.

Water flows into town through large transmission pipelines and enters a grid of some 1600 miles of distribution water mains, buried below city streets bringing water from our protected watersheds to you.

Seattle Public Utilities (SPU) performs projects to maintain, rehabilitate, and replace its water system infrastructure. This work includes:

  • Water Main Rehabilitation: SPU invests in construction projects to rehabilitate and replace water mains throughout the city.
  • Cathodic Protection: SPU installs cathodic protection systems in the ground to prevent pipe corrosion and preserve the integrity and extend the life of its water transmission pipelines.
  • Water System Facility Upgrades: SPU rehabilitates, upgrades and replaces aging pump stations, storage tanks and reservoirs as their components reach the end of life or need to be brought up to new seismic standards.
  • Maintenance Work: SPU Water Crews respond to emergencies and perform ongoing maintenance of our water system.

SPU also partners with Seattle Department of Transportation (SDOT) and other City departments and agencies to rehabilitate water mains as part of their construction projects, which reduces costs and minimizes construction impacts to the community.

SPU is continuing to make upgrades to our system - from tanks, to reservoirs, to our protected watersheds - to provide high-quality, reliable services to our customers. Learn more about SPU's current and completed projects.
