For the purpose of this chapter, the following terms shall be defined as follows:
BACKFLOW: The reverse from normal flow direction of water, or mixtures of water and other liquids, gases or other substances into the distribution lines of the city public water system from any source or sources.
BACKFLOW ASSEMBLY TESTER (BAT): A person who tests approved backflow prevention assemblies and holds a current backflow assembly tester (BAT) license issued in the state of Idaho for the purpose of conducting field performance tests and inspections of approved backflow prevention assemblies as defined in title 54, chapter 24 of Idaho Code.
BACKFLOW PREVENTION ASSEMBLY - APPROVED: An assembly approved by the city water superintendent that complies with the requirements of the Idaho rules for public drinking water systems (IDAPA 58.01.08). This assembly, when properly installed and maintained between the city water supply system and the terminus or point of ultimate use, prevents backflow.
BACKFLOW PREVENTION DEVICE - APPROVED: An air gap (AG) or atmospheric vacuum breaker (AVB) device or method approved by the city water superintendent that complies with the requirements of the Idaho rules for public drinking water systems (IDAPA 58.01.08). This device or method, when properly installed and maintained between the city water supply system and the terminus or point of ultimate use, prevents backflow.
CITY WATER SUPERINTENDENT: The person hired by the city to oversee the operation and maintenance of the city's water system or his or her designee.
CROSS CONNECTION: Any actual or potential connection or structural arrangement between a public or consumer's potable water system or any other source or system through which it is possible to introduce into any part of the city's public water system any used water, industrial fluid, gas, or substance other than the intended potable water with which the system is supplied. Bypass arrangements, jumper connections, removable sections, swivel or change over devices and other temporary or permanent devices through which or because of which backflow can occur are considered to be cross connections.
FIELD TEST KIT: An instrument, either mechanical or electronic in design, and all related fittings, tools, equipment and appurtenances necessary to conduct performance tests on approved backflow prevention assemblies.
PERFORMANCE TEST: The testing of an approved backflow prevention assembly using the latest test procedures, as defined by the University Of Southern California Foundation For Cross Connection Control And Hydraulic Research (USCFCCCHR) and consistent with the backflow assembly tester's most recent training course and/or practical exam to certify that the backflow prevention assembly is functioning properly and within factory tolerances as designed.
