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 a new section that emphasizes the importance of water systems as critical utilities and recognizes the need for the Utilities and Transportation Commission (UTC) to have specific statutory standards for reviewing proposed rate changes. The bill mandates that water systems 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 seeks to improve consumer notice 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 water rates, including establishing 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. Overall, the bill aims to create a more structured and consumer-friendly approach to water system regulation in Washington.
