For purposes of the cross-connection control program, the following definitions apply:

1. “Backflow” is the flow of water or other liquids, fluids, gases, or any substance whatsoever from a source outside the public water supply back into the public water supply. Backflow or reversed flow may occur due to either back pressure (pushing) or back siphonage (pulling).

2. “Backflow prevention device” is a device or assembly, approved by the director or health officer, designed and tested to counteract back pressure and back siphonage.

3. “Containment” is a method of backflow prevention requiring the installation of a backflow prevention assembly or device at the point a water service line enters the premises served.

4. “Contamination” is the entry into or presence in the public water supply of any substance which the director or health officer determines will or might adversely affect the public health or the aesthetic qualities of the water (appearance, taste, or odor).

1. 1. “Contaminated water” is water with contamination.

5. “Cross-connection” is any physical arrangement whereby the public water supply of the City of Spokane is connected, directly or indirectly, or in the judgment of the director or health officer has a risk of becoming connected, to a source of contamination as a result of backflow. Sources of contamination might include, but are not limited to:

1. 1. public or private water supply system,

1. 2. tank or storage reservoir,

1. 3. sewer line,

1. 4. sewer drain,

1. 5. conduit,

1. 6. pool, or

1. 7. any plumbing or fixture whatsoever.

6. “Cross-connection control manual” or “Manual” is the latest edition of “Accepted Practice and Procedure in Cross-Connection Control” promulgated by the Pacific Northwest section of the American Waterworks Association. A copy of the manual is available for public inspection at the water and hydroelectric services department offices.

7. “Cross-connection control program” is the City of Spokane’s effort to prevent and control cross-connections, as required by WAC 246-290-490, expressed in the cross-connection control manual, SMC 13.04.0814 through SMC13.04.0824, and any regulations or orders issued by the director in implementation of said program.

1. “Director” is the director or administrative head of the water and hydroelectric services department.

10. “Isolation” is a method of backflow prevention where a backflow prevention assembly or device is located at a point of a cross-connection, rather than the premises or property line.
