As used in this Article, the following terms shall have the meanings indicated:
APPROVEDAccepted as meeting an applicable specification stated or cited in this Article or as suitable for the proposed use.
AUXILIARY WATER SUPPLYAny water supply on or available to the premises other than the generally recognized public potable water supply. These "auxiliary waters" may include water from another purveyor's public potable water supply or any natural source such as a well, spring, river, stream, harbor, etc., or used waters or industrial fluids. They may be polluted or contaminated or they may be objectionable and constitute an unacceptable water source over which the water purveyor does not have sanitary control.
BACKFLOWThe flow of water or other liquids, mixtures or substances into the distribution pipes of a potable water supply from any source or sources other than its intended source. Back-siphonage is one type of "backflow."
BACKFLOW PREVENTERA device or means to prevent backflow.
A. Air-gap primary prevention. 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 the receptacle.
B. Reduced pressure principal primary prevention. The term "approved reduced pressure principal backflow prevention device" means a device approved by a recognized and city-approved testing agency for backflow prevention devices.
CONTAMINATIONAn impairment of the quality of the water by sewage or industrial fluids or waste to a degree which creates an actual hazard to the public health, such as but not limited to poisoning or through the spread of disease. (See "pollution.")
CROSS-CONNECTIONAny physical connection or arrangement of piping or fixtures between two otherwise separate piping systems, one of which contains potable water and other nonpotable water or industrial fluids of questionable safety, through which or because of which backflow may occur. A water service connection between a public potable water distribution system and a customer's water distribution system which cross-connected to a contaminated fixture, industrial fluid system or with a potentially contaminated supply or auxiliary water system constitutes one type of "cross-connection." Other types of "cross-connections" include connectors such as swing connections, removable sections, four-way plug valves, spools, dummy sections of pipe, swivel or changeover devices, sliding multiport tube, etc.
CROSS-CONNECTION CONTROL BY CONTAINMENTThe installation of an approved backflow prevention device immediately after the meter on any customer's premises where an actual or potential cross-connection exists on a customer's water system.
CROSS-CONNECTION, CONTROLLEDA connection between a potable water system and a nonpotable water system with an approved built-in backflow preventer that will continuously afford protection commensurate with the degree of hazard.
DOUBLE CHECK VALVE ASSEMBLY SECONDARY PREVENTIONAn assembly of at least two independently acting approved check valves including tightly closing shutoff valves on each side of the check valve assembly and suitable leak detector drains plus connections available for testing the watertightness of each valve.
HAZARD, DEGREE OFThe term is derived from an evaluation of the potential risk to public health and the adverse effect upon the potable water system.
A. HAZARD, HEALTHAny condition, device or practice in the water supply system and its operation which could create or, in the judgment of the official head, may create a danger to the health and well-being of the water consumer. An example of a "health hazard" is a structural defect, including cross-connections, in a water supply system.
B. HAZARD, PLUMBINGA 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 other device. Unprotected plumbing-type cross-connections are considered to be a health hazard.
C. HAZARD, POLLUTIONALAn actual or potential threat to the physical properties of the water system or 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.
D. HAZARD, SYSTEMAn 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 protracted effect on the quality of the potable water in the system.
INDUSTRIAL FLUIDS SYSTEMAny 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 public potable water supply. This may include but not be limited to polluted or contaminated waters; all types of process waters and used water originating from the public potable water system which may have deteriorated in sanitary quality; chemicals in fluid form; plating acids and alkalies; circulated cooling waters that are connected to an open cooling tower and/or cooling waters that are chemically or biologically treated or stabilized with toxic substances; contaminated natural waters such as from wells, springs, streams, rivers, bays, harbors, seas, irrigation canals or systems, etc.; oils, gases, glycerine, paraffins, caustic and acid solutions and other liquid and gaseous fluids used in industrial or other processes or for fire-fighting purposes.
POLLUTIONThe presence of any foreign substances (organic, inorganic, radiological or biological) in water which tends to degrade its quality as to constitute a hazard or impair the usefulness or quality of the water to a degree which does not create an actual hazard to the public health, but does adversely and unreasonably affect such waters for domestic use. (See "contamination.")
PUBLIC WATER SYSTEMA system for the provision to the public of piped water for human consumption, if such system has at least 15 service connections or regularly services at least 25 individuals.
THE GREATER JOHNSTOWN WATER AUTHORITYThe utility in charge of supplying potable water to consumers within the City of Johnstown, which is invested with the authority and responsibility for the implementation of an effective cross-connection control program and for the enforcement of the provisions of this Article.
WATER, NONPOTABLEWater which is not safe for human consumption or which is of questionable potability.
WATER, POTABLEAny water which, according to recognized standards, is safe for human consumption.
WATER, SERVICE CONNECTIONSThe terminal end of a service connection from the potable water system, i.e., where the water purveyor loses jurisdiction and sanitary control over the water at its point of delivery to the consumer's water system. There should be no unprotected takeoffs from the service line ahead of any meter or backflow prevention device located at the point of delivery to the consumer's water system. "Service connection" shall also include water service connection from a fire hydrant and all other temporary or emergency water service connection from the public potable water system.
WATER SYSTEMThe "water system" shall be considered as made up of two parts: the utility system and the customer system.
A. The utility system shall consist of the source facilities and the distribution system and shall include all those facilities of the water system under the complete control of the utility, up to the point where the customer's system begins.
(1) The source shall include all components of the facilities utilized in the production, treatment, storage and delivery of water to the distribution system.
(2) The distribution system shall include the network of conduits used for the delivery of water from the source to the customer's system.
B. The customer system shall include those parts of the facilities beyond the termination of the utility distribution system which are utilized in conveying utility-delivered domestic water to points of use.
WATER, USEDAny water supplied by a water purveyor from a public potable water system to a consumer's water system after it has passed through the point of delivery and is no longer under the sanitary control of the water purveyor.
