The bill aims to enhance transparency and consumer protection in water system rates in Washington state. It introduces a new section that emphasizes the importance of water systems as critical utilities and acknowledges the lack of specific statutory standards for the Utilities and Transportation Commission (UTC) in reviewing water rate changes. The bill mandates that water companies provide detailed planning materials and information regarding capital investments to the UTC, ensuring that rate changes are just, fair, and reasonable. Additionally, it seeks to improve consumer notice regarding planned investments and their potential impacts on rates, thereby preventing sudden and significant rate increases.

Key amendments to existing laws 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 establishes new rules for the UTC to adopt a structured approach to determining water rates, including setting ceilings on returns and requiring detailed justifications for any proposed increases. Furthermore, it mandates that all capital improvement projects be included in the water system plan approved by the Department of Health, promoting transparency and accountability in the rate-setting process.
