Cross Connection
– any physical arrangement or potential arrangement whereby the District’s water system is or may be connected, directly or indirectly, with any other water supply system, sewer, drain, conduit, pool, storage reservoir, plumbing fixture, or other device which contains, or may contain, contaminated water, sewage, or other waste or liquid of unknown quality which may be capable of having the potential to contaminate the District’s water supply as the result of backflow or backsiphonage. By-pass arrangements, jumper connections, removable sections, swivel or changeable devices, and other temporary or permanent devices through which, or because of which, a backflow or backsiphonage may occur, are considered to be cross-connections.
