The Walla Walla Department of Community Health works with the Washington State Department of Health to monitor public water systems, coordinate and/or approve new water systems, investigate complaints related to waterborne illnesses, and provide material for the collection of water samples for bacterial analysis. Technical assistance is available to private homeowner water systems.

Group B Public Water Systems

In general, systems that serve between 3-10 connections and some single connections that need licensing need to go through the process of converting a well into a public water system. The Walla Walla County Department of Community Health can approve any group B water systems. Below are the design workbook and guidelines. An engineer with knowledge of designing public water system needs to complete the workbook. A $500 workbook review fee is required for all systems that wish to become public water systems.
