Group A

These are water supplies that regularly serve 15 or more residential connections, 25 or more people per day for 60 or more days per year, or 1000 people for two days or more per year. Group A systems are regulated by the Washington State Department of Health (WSDOH) under WAC 246-290; Lewis County has an agreement with the State on Group A projects to administer and review WAN's and Well Site Inspections (see permitting and applications below).

If you are interested in developing or revising a Group A system contact WSDOH at (360) 236-3030. For information on Group A Systems see the Washington State Department of Health Drinking Water Program.
