For the purpose of this subchapter, the following definitions shall apply unless the context clearly indicates or requires a different meaning.
   ADMINISTRATIVE AUTHORITY. The Water and Sewer Committee of the city, its designated representatives, and officials from the Tontitown Building Inspector's Office. The Administrative Authority is vested with the responsibility to enforce provisions of this subchapter.
   AIR GAP. The unobstructed vertical distance through the free atmosphere between the lowest opening from any pipe or faucet conveying water or waste to a tank, plumbing fixture or other assembly and the flood level rim of the receptacle. These vertical or physical separations must be at least twice the diameter of the water supply outlet and never less than one inch (25 mm).
   APPROVED. Accepted by the Administrative Authority as meeting any applicable specifications as stated in this subchapter or being suitable for the proposed use.
   AUXILIARY WATER SUPPLY. Any water supply on or available to the user's premises, other than that supplied by the municipal water system of the city. Auxiliary waters may include water from another public water system or any natural sources such as a well, spring, river, stream, and so forth, 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 city does not have sanitary control.
   BACKFLOW. The undesirable reversal of flow in a potable water distribution system as a result of a cross connection.
   BACKFLOW-PREVENTION ASSEMBLY. An assembly or means designed to prevent backflow. Acceptable means and devices for backflow prevention include:
      (1)   Air gap;
      (2)   Reduced-pressure backflow-prevention assembly; and
      (3)   Double check valve assembly.
   BACKPRESSURE. A pressure, higher than the supply pressure, caused by a pump, elevated tank, boiler, or any other means that may cause the backflow of water from a nonpotable water system to a potable water system.
   BACKSIPHONAGE. Backflow caused by negative or reduced pressure in the supply piping.
   CITY WATER. Water supplied by the municipal water system of the City of Tontitown, Arkansas.
   CONTAMINATION. An impairment of potable water supply by the introduction or admission of any foreign substance that degrades the quality and creates a health hazard.
   CONTRACT WATER USERS. All persons and entities who purchase water from the Tontitown Water Department, for individual use, resale, and/or redistribution.
   CROSS CONNECTION. A connection or potential connection between a part of a potable water system and any other environment containing other substances in a manner that under any circumstances would allow such substances to enter the potable water system. Other substances may be gases, liquids, or solids, such as chemicals, waste products, steam, water from other sources (potable or nonpotable), or any matter that may change the color or add odor to the water.
   CROSS CONNECTIONS - CONTROLLED. A connection between a potable water system and a nonpotable water system with an approved backflow-prevention assembly property installed and maintained so that it will continuously afford the protection commensurate with the degree of hazard.
   CROSS CONNECTION CONTROL BY CONTAINMENT. The installation of an approved backflow-prevention assembly at the water service connection to any user's premises, where it is physically and economically unfeasible to find and permanently eliminate or control all actual or potential cross connections within the user'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 user'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.
   DOUBLE CHECK VALVE ASSEMBLY. The approved double check valve assembly consists of two internally loaded check valves, either spring loaded or weighted, installed as a unit between two tightly closing resilient-seated shutoff valves. This assembly shall only be used to protect against a non-health hazard (that is, a pollutant).
   HAZARD, DEGREE OF. The terms derived from an evaluation of the potential risk to public health and the adverse effect of the hazard upon the potable water system.
   HAZARD - HEALTH. A cross connection or potential cross connection involving any substance that could, if introduced in the potable water supply, cause death, illness, spread disease, or have a high probability of causing such effects.
   HAZARD - NONHEALTH. A cross connection or potential cross connection involving any substance that generally would not be a health hazard but would constitute a nuisance or be aesthetically objectionable, if introduced into the potable water system.
   HAZARD - PLUMBING. A plumbing-type, cross connection in a user's potable water system that has not been properly protected by an approved air gap or an approved backflow-prevention assembly.
   HAZARD - SYSTEM. An actual or potential threat of severe damage to the physical properties of the public potable water system or the user's potable water system, or a pollution or contamination that would have a protracted effect on the quality of the potable water in the system.
   INDUSTRIAL FLUID SYSTEMS. Any system containing a fluid or solution that may be chemically, biologically, or otherwise contaminated or polluted in a form or concentration, such as would constitute a health, system, pollution, or plumbing hazard, if introduced into an approved water supply. This may include, but not be limited to: polluted or contaminated waters; all types of process waters, and used waters originating from the municipal water system that may have deteriorated in sanitary quality; chemicals in fluid form plating acids and alkalines; circulating cooling waters connected to an open cooling tower, and/or cooling towers that are chemically or biologically treated or stabilized with toxic substances; contaminated natural water, such as wells, springs, streams, rivers, bays, harbors, seas, irrigation canals or systems, and so forth; oil, gases, glycerin, paraffins, caustic and acid solutions and other liquids and gaseous fluids used in industrial or other purposes or for fire-fighting purposes.
   NONPOTABLE WATER. Water that is not safe for human consumption or that is of questionable quality.
   POLLUTION. The presence of any foreign substance in water that tends to degrade its quality so as to constitute a non-health hazard or impair the usefulness of the water.
   POTABLE WATER. Water that is safe for human consumption as defined by the Arkansas Department of Health and the U.S. Environmental Protection Agency.
   PRIVATE WATER SYSTEM. The user's water supply system of a building or premises that includes water-service pipe beyond the termination of the municipal water system, the water-distribution pipes and the necessary connecting pipes, fittings, control valves and all appurtenances in or adjacent to the building or premises.
   PUBLIC WATER SYSTEM. Facilities owned and maintained by the municipal water system utilized in the transmission, storage, distribution and metering of potable water.
pressure principle backflow-prevention assembly consists of two independently acting approved check valves together with a hydraulically operating mechanically independent pressure differential relief valve located between the check valves and below the first check valve. These units are located between two tightly closing resilient-seated shutoff valves as an assembly and equipped with properly located resilient-seated test cocks.
   SERVICE CONNECTION. The terminal end of a service connection from the municipal water system, that is, the point where the user assumes control of the water system providing service to the premises. For metered services, the service connection is a point immediately outside the meter box where the user has connected to the piping supplied by the municipal water system as a part of the meter setting. For unmetered fire protection systems, the service connection is the designated control valve owned and maintained by the municipal water system.
   TONTITOWN BUILDING INSPECTOR. Officials of the city licensed by the Arkansas Department of Health to enforce provisions of the State Plumbing Code.
   TONTITOWN WATER AND SEWER COMMITTEE. The Board of the Water and Sewer Committee, established by Ord. 2012-11-434, for the purpose of operating and maintaining the municipally owned water system of the city.
