King County Adopted Sewer Rate Increases 12.75%

On June 23, 2026, the King County Council adopted a 12.75% wastewater rate increase, effective January 1, 2027.

Your sewer bill covers costs for work by both CRWSD and the King County Wastewater Treatment Division.

The King County portion of your sewer bill covers costs to maintain and operate treatment plants that collect and clean wastewater, and funds projects to upgrade aging infrastructure, meet environmental regulations, and increase capacity. The King County Council sets the rate each year, and agencies like CRWSD pass costs to customers through our own rate structure.

Drought Declaration

On April 8, 2026, Ecology issued a drought declaration for all watersheds in the state due to low snowpack and multiple years of precipitation deficits. This is the state’s fourth consecutive drought declaration. Based on current conditions and forecasts, Seattle anticipates the regional water system will have sufficient water supply for people and fish this summer. As always, we continue to ask customers to use water wisely.
