For the purposes of this chapter the following definitions shall apply unless the context clearly indicates or requires a different meaning:
AIR-GAP. The unobstructed vertical distance through the free atmosphere between the lowest opening from any pipe or faucet supplying water to a tank, plumbing, fixture or other device and the flood level rim of said vessel. An approved air-gap shall be at least double the diameter of the supply pipe, measured vertically, above the overflow rim of the vessel; and in no case less than one inch.
APPROVED. Accepted by the Kouts Water Utility as meeting an applicable specification stated or cited in this chapter, or suitable for the proposed use.
AUXILIARY WATER SUPPLY. Any water supply on or available to the premises other than the utility's approved public water supply.
BACKFLOW. The reversal of normal flow of water caused by either back pressure or backsiphonage.
BACKFLOW PREVENTER. An approved assembly or means designed to prevent backflow.
BOOSTER PUMP. A pump installed on a pipeline to increase water pressure or flow.
CONTAMINATION. An impairment of the quality of the potable water by sewage, industrial fluids, compounds or other materials to a degree which creates an actual or potential hazard to the public health.
CROSS-CONNECTION. Any physical connection or arrangement of piping, including cross- connection control devices not in working order, whereby a public water supply distribution system is directly connected, either continuously or intermittently, with any secondary source of supply which contains or may contain, and is capable of imparting to the public water supply, contaminants, contaminated water, or any other waste or liquid of unknown or unsafe quality.
CROSS-CONNECTION CONTROL DEVICE. Any device or assembly which is capable of preventing contaminants from entering the public water supply distribution system.
CROSS-CONNECTION CONTROL DEVICE INSPECTOR. A person who has successfully completed training in testing and inspection of cross- connection control devices from a training provider approved by the Commissioner of the Indiana Department of Environmental Management and has received a registration number from the Commissioner.
CROSS-CONNECTION HAZARD. Any customer facility which, because of the nature and extent of activities or the materials used in connection with the activities or stored on the premises, would present an immediate or potential danger or health hazard to customers of the public water supply should backflow occur.
CUSTOMER. Any person who receives water from a public water supply.
CUSTOMER SERVICE LINE. The pipeline from the public water supply to the first tap, fixture, receptacle or other point of customer water use.
CUSTOMER WATER SYSTEM. All piping and fixtures, including secondary sources of supply, used by a customer to convey water on his premises.
DOUBLE CHECK VALVE ASSEMBLY. A device composed of two tightly closing shut-off valves surrounding two independently acting check valves, with four test cocks, one upstream of the four valves and one between each of the four check and shut-off valves.
DOWNSTREAM. The direction of flow when only the public water supply is supplying water through the customer water system and backflow is not occurring.
PRESSURE VACUUM BREAKER. A device containing an independently operating internally loaded check valve and an independently operating loaded air inlet valve located on the downstream side of the check valve for relieving a vacuum or partial vacuum in a pipeline.
PUBLIC WATER SYSTEM. Sources of supply including mains, pumps and structures through which water is obtained, treated as may be required, and supplied through a water distribution system.
REDUCED PRESSURE PRINCIPLE BACKFLOW PREVENTER. A device composed of two tightly closing shut-off valves surrounding two independently acting pressure reducing check valves that, in turn, surround an automatic pressure differential relief valve and four test clocks, one upstream of the five valves and one between each of the four check and shut-off valves. The check valves effectively divide the structure into three chambers, pressure is reduced in each downstream chamber allowing the pressure differential relief valve to vent the chamber to the atmosphere should either or both check valves malfunction.
SECONDARY SOURCE OF SUPPLY. Any well, spring, cistern, lake, stream or other water source, intake structure, pumps, piping, treatment units, tanks and appurtenances used, either continuously or intermittently, to supply water other than from the public water supply to the customer, including tanks used to store water to be used only for fire fighting, even though the water contained therein is supplied from public water supply.
