HB 1906 Washington House · 2025-2026 Regular Session

Increasing transparency and consumer protection in water system rates.

HB 1906 requires water systems in Washington to share detailed capital improvement plans and cost information with the Utilities and Transportation Commission (UTC) when seeking rate increases. This ensures the UTC can better review whether proposed costs are properly justified and rates are fair, while also mandating that consumers receive clearer notice about planned investments and their expected rate impacts. The bill directly affects water utilities, the UTC (the regulatory agency), and ratepayers (water customers). It amends state law to create structure for rate reviews, addressing gaps where current processes lacked standards for evaluating capital costs tied to public health requirements.

The legislation also introduces a new multiyear rate plan option for water companies starting in 2027.
