Backflow assemblies

In 2007 we bagan requiring all commercial facilities to have an Reduced Pressure Backlow Assembley (RPBA) near the service meter. If you have an irrigation system, you must have a Double Check Valve Assembly (DCVA) near the service meter. All of the backflow assemblies must be tested on an annual basis. We will send out an annual reminder.

We strive to provide you with safe, high quality water that meets or exceeds all federal and state standards. Water quality is tested daily by water company employees and on a regular schedule that includes weekly, annual, and tri-annual analysis by Washington State and EPA certified laboratories.

If you would like more information about contaminants, or any other water issues, we will be happy to answer your questions. Please call (253) 531-9024 and ask for Tim Tayne, Water Quality Manager.
