The bill creates a new safe drinking water grant program in chapter 70A.125 RCW to provide only grants (no loans are specified) to eligible public water systems located in "economically distressed communities" that do not meet state drinking water standards. Grants are for capital improvements and for planning; applicants for planning grants must submit a brief statement about water quality, system deficiencies, and financial constraints, and construction grant applicants must either have completed a planning grant or provide construction documents plus a similar statement. The department administering the program must develop an application process and project evaluation criteria by January 1, 2026, give primary consideration to drinking water quality and financial need, and beginning with the 2027–2029 biennium must submit a prioritized list of recommended projects and funding amounts to the governor and the legislature; program funding is subject to amounts specifically appropriated. The bill also amends RCW 43.20.050 to retain and specify State Board of Health authorities and duties, including rulemaking for group A and group B public water systems, adoption of public health rules, and maintenance and enforcement of drinking water standards as required by applicable federal law (42 U.S.C. § 200f et seq.). It directs the state board to adopt rules for on-site sewage systems with design flows under 3,500 gallons per day and establishes minimum fines for failure to enforce state board rules: not less than $50 on first conviction and not less than $100 on second conviction. In legal terms, the bill creates a new statutory program (a new section in chapter 70A.125 RCW), modifies existing law in RCW 43.20.050, imposes a procedural change (new application, evaluation, and biennial prioritization requirements), and changes penalties by setting minimum fines for enforcement failures. Important details are not provided in the extracted text: the bill does not include the definition of "economically distressed community," the text of RCW 70A.125.010 (defining public water systems, group A, and group B), the specific department named to administer the program, the new section number added to chapter 70A.125 RCW, or any appropriation amount or funding source.

If enacted, the bill would create a grant program that can pay for planning work and capital repairs, consolidation, or redesign of public water systems in places the bill calls "economically distressed communities" that do not meet state drinking water standards. Eligible systems could get grants (not loans) if they provide required planning or construction documents, and the agency running the program must set application rules by January 1, 2026 and then include a prioritized list of recommended projects in the state’s capital budget request starting in the 2027–2029 biennium, with priority to the worst water quality. The State Board of Health keeps its rulemaking and enforcement duties, must adopt on-site sewage rules for small flows, and the measure sets minimum fines for failing to enforce board rules. The most affected parties are small or struggling public water systems in designated economically distressed communities, which may have a new funding option that reduces the need for local borrowing or up-front capital but whose actual help depends on future appropriations and on meeting the program’s documentation requirements. The department that will run the program and the State Board of Health will take on new or continued duties around applications, project prioritization, and enforcement; local officials face minimum fines for enforcement failures. Key details are missing from the extracts — notably the exact definition of “economically distressed community,” which agency will administer the grants, and any specific appropriation amounts — so the scope and pace of real funding and impact are uncertain.
