The following definitions shall apply in the interpretation and enforcement of this Article:

AIR-GAP SEPARATION: 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 overflow level rim of the receptacle, and shall be at lease double the diameter of the supply pipe measured vertically above the flood level rim of the vessel, but in no case less than one (1) inch.

AUXILIARY BACK FLOW: The flow, other than the intended direction of flow, of any foreign liquids, gases, or substances into the distribution system of a public water supply.

AUXILIARY WATER SUPPLY: Any water source or system, other than the public water supply, that may be available in the building or premises.

BACKFLOW PREVENTION DEVICE: Any device, method, or type of construction intended to prevent backflow into a potable water system.

CONTAINMENT: Protection of the public water supply by installing a cross-connection control device or air-gap separation on the main service line to a facility.

CONTAMINATION: An impairment of the quality of the water by sewage, process fluids, or other wastes to a degree which could create an actual hazard to the public health through poisoning or through spread of disease by exposure.

CROSS-CONNECTION: Any physical link between a potable water supply and any other substance, fluid, or source, which makes possible contamination of the potable water supply due to the reversal of flow of the water in the piping or distribution system.

CUSTOMER: Any person who receives water from a public water system, except those persons receiving water for resale.

HAZARD, DEGREE OF: An evaluation of the potential risk to public health and the adverse effect of the hazard upon the potable water system.

1. Hazard, Health. Any condition, device, or practice in the water supply system and its operation which could create or may create a danger to the health and well-being of the water consumer.

2. Hazard, Plumbing. A plumbing type cross-connection in a consumer's potable water system that has not been properly protected by a vacuum breaker, air-gap separation or backflow prevention device.

3. Hazard, Pollutional. An actual or potential threat to the physical properties of the water system or to the potability of the public or the consumer's potable water system but which would constitute a nuisance or be aesthetically objectionable or could cause damage to the system or its appurtenances, but would not be dangerous to health.

4. Hazard, System. An actual or potential threat of severe damage to the physical properties of the public potable water system or the consumer's potable water system, or of a pollution or contamination which would have a protracted effect on the quality of the potable water in the system.

INDUSTRIAL PROCESS SYSTEM: Any system containing a fluid or solution which may be chemically, biologically, or otherwise contaminated or polluted in a form or concentration such as would constitute a health, system, pollutional, or plumbing hazard if introduced into a potable water supply.

ISOLATION: Protection of a facility service line by installing a cross-connection control device or air-gap separation on an individual fixture, appurtenance, or system.

POLLUTION: The presence of any foreign substance (organic, inorganic, or biological) in water which tends to degrade its quality so as to constitute a hazard or impair the usefulness of the water to a degree which does not create an actual hazard to the public health but which does adversely and unreasonably affect such waters for domestic use.

PUBLIC WATER SYSTEM: A system for the provision to the public of water for human consumption through pipes or other constructed conveyances, if such system has at least fifteen (15) service connections or regularly serves an average of at least twenty-five (25) individuals daily at least sixty (60) days per calendar year. Such system includes any collection, treatment, storage or distribution facilities used in connection with such system.

WATER PURVEYOR: The owner, operator, or individual in responsible charge of a public water system.
