Dear Customer,

In accordance with Washington State Department of Health (DOH) regulations (WAC 246-290-490), the City of Orting administers a Cross-Connection Control Program to protect the public drinking water supply from potential sources of contamination.

A cross-connection is any actual or potential physical link between a potable (drinking) water system and any source containing non-potable water, chemicals, or other substances that could contaminate the public water supply. If pressure is lost in the water system—for example, during a water main break or heavy usage—backflow may occur, allowing non-potable substances to flow backward into the drinking water system.

To minimize this risk, the Washington State DOH requires all public water systems to conduct hazard assessments and maintain records of potential cross-connections. Residential irrigation systems (such as lawn sprinklers) are among the most common hazards. Commercial and industrial properties pose additional risks due to more complex plumbing systems and specialized water uses.

As part of our required compliance efforts, the City of Orting is conducting a system-wide Cross-Connection Survey. The Cross-Connection Survey on the following page must be completed by all customers to help us identify and assess potential hazards.

Once submitted, the survey answers will go to the City of Orting Public Works Department. A response is required from all customers to ensure our records are accurate and to remain in compliance with state drinking water safety regulations.

If you have any questions or need assistance, please contact the Public Works Department at (360) 893-9039, Monday through Friday, between 7:30 a.m. and 4:00 p.m.

Thank you for your cooperation and for helping to protect our community’s drinking water.

Sincerely,
Public Works Department
City of Orting
