Resources and guidance to help you navigate information about your water
A Note About Backflow Prevention
Beginning in 2007, water purveyors in Washington were required by Washington State Administrative Code (WAC 246-290-490) to establish a cross-connection control program to prevent contamination of our public drinking water system by unintended backflow.
Although rare, the possibility of contamination through cross-connection does exist and is a very real threat to all of us! Water can reverse its flow (backflow) when there is a severe drop in pressure. Read more about backflow prevention.
Vashon-Maury Water Resources
In 2011 King County sent the Protecting Our Liquid Assets mailer to Vashon and Maury Island residents to provide information about our natural water resources and how they are used. You can view it here.
