(1) "Water purveyor": The responsible charge operator of the City, is invested with the authority and responsibility for the implementations of an effective cross connection control program and for the enforcement of the provisions of this Ordinance.
(2) "Approved backflow assembly": An assembly accepted by the Utah State Department of Environmental Quality, Division of Drinking Water, as meeting applicable specifications or as suitable for the proposed use.
(3) "Auxiliary water supply": Any water supply on or available to the premises, other than the purveyor's public water supply, will be considered as an auxiliary water supply. These may include water from another purveyor's public potable water supply or any natural source such as a well, spring, river, stream, ditch, secondary water system, etc., or "used waters" or industrial fluids. These waters may be contaminated or polluted, or they may be objectionable and constitute an unacceptable water source over which the water purveyor does not have authority for sanitary control.
(4) "Backflow": The reversal of the normal flow of water caused by either back-pressure or back-siphonage.
(5) "Back-pressure": The flow of water or other liquids, mixtures, or substances under high pressure to a region of lower pressure into the water distribution pipes of a potable water supply system from any source(s) other than the intended source.
(6) "Back-Siphonage": The flow of water or other liquids, mixtures, or substances under vacuum condition into the distribution pipes of a potable water supply system from any source other than the intended source, caused by the reduction of pressure in the potable water supply system.
(7) "Backflow prevention assembly": An assembly or means designed to prevent backflow. Specifications for backflow prevention assemblies are contained within the Uniform Plumbing Code, and in the Cross Connection Control Program of Utah maintained by the Division of Drinking Water.
(8) "Contamination": A degradation of the quality of the potable water supply by sewage, industrial fluids, or waste liquids, auxiliary water supply, compounds, or other materials.
(9) "Cross connection": Any physical connection or arrangement of piping or fixtures which may allow non-potable water or industrial fluids or other material of questionable quality to come in contact with potable water inside a distribution system. This would include any temporary connections such as swing connections, removable sections, four-way plug valves, spools, swivel or change-over valves or devices, or sliding multiport tubes, or other plumbing arrangements.
(10) "Cross connection – Controlled": A connection between a potable water system and a non-potable water system with an approved backflow prevention assembly properly installed and maintained so that it will continuously afford the protection commensurate with the degree of hazard.
(11) "Cross connection – Containment": The installation of an approved backflow assembly at the water service connection to a customer's premises, where it is physically and economically infeasible to find, permanently eliminate, or control all actual or potential cross connections within the customer's water system; or it shall mean the installation of an approved backflow prevention assembly on the service line leading to and supplying a portion of a customer's water system where there are actual or potential cross connections that cannot be effectively eliminated or controlled at the point of the cross connection (isolation) and before the first branch line leading off the service line.
(12) "Service connection": The service connection shall be defined as the water meter yoke assembly with the City being responsible up to the discharge piping from the meter yoke.
