In 2024, the King County Water District No. 125 Board of Commissioners hired an independent financial consultant to evaluate the District’s existing rate structure, projected operating costs, and future infrastructure needs. Based on this review, the consultant recommended annual rate adjustments in 2025, 2026, and 2027 to address rising operating costs, inflation, and the ongoing expense of maintaining and improving the District’s water system.
In September 2026, the District was notified by Seattle Public Utilities (SPU), which supplies the District's drinking water, of an additional increase in wholesale water rates for 2027. This increase directly impacts the District's cost of purchasing water for its customers.
The Board of Commissioners will hold a public rate hearing on Thursday, November 12, 2026, at 3:00 p.m. at the District office to review and discuss the proposed 2027 water rates, including the impact of SPU's wholesale rate increase.
