Group B water systems

The Washington State Department of Health permits all new Group B water systems.

King County requires all water systems serving two or more parcels to be permitted as a Group B public water system. The Washington State Department of Health will permit a Group B water system to support two parcels by designing the system for four connections (two connections for each parcel). This will allow each property the option of one connection for the main residence and a second for an accessory dwelling unit or provide an additional connection for a neighboring property in the future.

For Group B water systems originally permitted by King County, historic records are maintained at the Eastgate Office. Please note, they are filed by water system name.
