Call for help

Sewage contains disease-causing contaminants that can require extensive clean up and restoration.
Sewage contains disease-causing contaminants that can require extensive clean up and restoration.

  • Contact your insurer and your local sewer district immediately. Know in advance what insurance coverage you have for sewer backups. Most sewage spills are due to blockages in a building's side sewer, which is private property. Your insurer and local sewer district can help you determine the appropriate course of action.
  • Consider hiring a professional water damage restoration service. If there is too much water to absorb using mops and sponges, professional water damage restoration experts can be found in the Yellow Pages under "Water Damage Restoration."
  • King County is ready to assist you. On rare occasions when the regional conveyance system contributes to a residential sewage spill, emergency cleanup support is available. If you have questions about a sewage spill you believe is related to the regional conveyance system, call King County's wastewater emergency hotlines:
    • 206-263-3801 (Seattle and North King County)
    • 206-684-2404 (South and East King County)
