Cross connection can be defined as any unprotected connection between any part of a water system used or intended to supply water for drinking purposes and any source or system containing water or substances that are not or cannot be approved as safe, wholesome, and potable for human consumption. The term is used in conjunction with backflow prevention. Bypass arrangements, jumper connections, removable sections and other devices through which backflow can occur are considered cross connections. Backflow is the physical process by which contaminants can enter the potable water supply.
No water service connection to any premises shall be installed or maintained by the Public Works Department unless the water supply is protected as required by said State regulations and the provisions of this section.
The purposes of the provisions in this section are to:
(a) Protect the public water supply against actual or potential cross connections by isolating within the premises contamination and pollution that may occur because of some undiscovered or unauthorized cross connection on the premises;
(b) Eliminate known cross connections.
