Water Protection/Cross Connection

Protecting Our Water Supply


Federal laws and Washington State regulations require the city’s Cross Connection Division be responsible for protecting the city’s domestic water supply from possible contamination and to investigate possible contamination sources. The most common source for possible contamination is when domestic water is used for landscape irrigation.
