This bill aims to enhance the consistency in the classifications of water systems in Washington State by amending existing definitions and regulations. Key changes include the clarification of the definitions for "Group A public water system" and "Group B public water system." The bill specifies that a Group A public water system is defined as one with 15 or more service connections, or serving an average of 25 or more people per day for 60 or more days within a calendar year, or serving 1,000 or more people for two or more consecutive days. Additionally, it introduces a provision that prevents the use of a default number of people served per connection to misclassify a water system that should be classified as Group B into Group A.

Furthermore, the bill allows local governments to establish separate operating permit requirements for public water systems, provided these requirements are approved by the Department of Health and result in an increased level of service. It also emphasizes that local requirements for Group B public water systems must be at least as stringent as state requirements, with a specific exception noted in the new language regarding Group A classifications. The act is declared necessary for the immediate preservation of public peace, health, or safety, and takes effect immediately upon passage.
