The bill aims to enhance transparency and consumer protection in water system rates in Washington State by amending several existing laws and introducing new requirements for water systems. It establishes that the Utilities and Transportation Commission (UTC) will have clearer statutory standards to guide its review and approval of proposed water system rate changes. The bill mandates that water systems must provide comprehensive planning materials and information regarding capital investments to the UTC, ensuring that rate changes reflect prudent costs and are just, fair, and reasonable. Additionally, it emphasizes the need for increased notice and transparency for consumers regarding planned investments and their potential impacts on rates.

Key amendments include the requirement for the state board to allow water system owners to have their water samples checked by local health departments without needing to contract with satellite management agencies. The bill also stipulates that the UTC must adopt rules for determining rates that include a ceiling on returns, a detailed analysis for higher returns, and considerations for consumer notification about capital projects. Furthermore, it requires that all capital improvement projects be included in the water system plan approved by the Department of Health, promoting a structured approach to rate setting that prioritizes consumer interests and public health.
