As used in this section, the following terms shall have the meanings indicated:
AIR GAP SEPARATIONA physical break between a supply pipe and a receiving vessel. The air gap shall be at least double the diameter of the supply pipe, measured vertically above the top rim of the vessel, and in no case less than one (1) inch.
APPROVED DOUBLE CHECK VALVE ASSEMBLYAn assembly of at least two (2) independently acting approved single check valves, including tightly closing shutoff valves on each side of the check valve assembly and suitable test cocks, plus connections available for testing the watertightness of each valve (Watts No. 007 or equal).
APPROVED REDUCED-PRESSURE PRINCIPAL BACKFLOW PREVENTION DEVICE (RPZ)A device incorporating two (2) or more single check valves and an automatically operating differential relief valve located between the two (2) checks and two (2) shutoff valves and equipped with necessary appurtenances for testing (Watts No. 009 or equal). The device shall operate to maintain the pressure in the zone between the two (2) check valves less than the pressure on the public water supply side of the device. At cessation of normal flow, the pressure between the check shall be less than the supply pressure. In case of leakage of either check valve, the differential relief valve shall operate to maintain this reduced pressure by discharging to the atmosphere. When the inlet pressure is two (2) pounds per square inch or less, the relief valve shall open to the atmosphere, thereby providing an air gap in the device. To be approved, these devices must be readily accessible for maintenance and testing and installed in a location where no part of the device will be destroyed.
APPROVED WATER SUPPLYAny water supply approved by or under the public health supervision of the public health agency of the State of New York, the County of Ulster or the Town of Marlborough. In determining what constitutes an "approved water supply," the Department of Health of the State of New York (herein called the "State Health Department") shall have the final judgment as to its safety and potability.
BACKFLOWA flow condition, induced by a differential in pressure, that causes the flow of water or other liquids and/or gases into the distribution pipes of the public water supply from any source other than its intended source.
CONSUMERAny person to whom water is sold and/or furnished from the Town of Marlborough.
CONTAMINATIONAn impairment of the quality of the Town water supply by the presence of any foreign substance (organic, inorganic, radiological or biological) to a degree which creates a hazard to the public health.
COUNTY HEALTH DEPARTMENTThe Ulster County Commissioner of Health, his assistants or authorized deputies acting as or any other person appointed as health officer of the County of Ulster.
CROSS-CONNECTIONAny unprotected connection between any part of the Town waterworks system used or intended to supply water for drinking purposes and any source or system containing water or substance that is not or cannot be approved as safe, wholesome and potable for human consumption.
NONTOXIC SUBSTANCEAny substance of a nonpoisonous nature that may create a moderate or minor hazard to the water supply system.
PERSONAny natural person, firm, association, organization, partnership, trust or association of persons, joint venture, corporation or company, and includes the United States, the State of New York, the County of Ulster, any special purpose district and any officer or agent thereof.
PREMISESIntegrated land area, including improvements thereon, undivided by public thoroughfares or water distribution mains of the Town of Marlborough and where all parts of the "premises" are operated under the same management and for the same purpose.
PROTECTIVE DEVICEAny of the following devices:
(b) Approved reduced-pressure principal backflow prevention device (RPZ).
(c) Approved double check valve assembly.
(d) Approved single check valve.
SERVICE CONNECTIONThe terminal end of a service connection from the Town water supply to its point of delivery to the consumer. If a meter is installed, "service connection" means the downstream end of the meter. No unprotected takeoffs from the service line ahead of any meter or backflow protective device located at the point of delivery to the consumer shall be permitted.
TOWNThe Town of Marlborough.
TOWN WATER SUPPLYAn approved water supply sold and delivered to consumers' premises through the waterworks system of the Town of Marlborough.
TOXIC SUBSTANCEAny substance (liquid, solid or gaseous), including raw sewage and lethal substances, that, when introduced into the water supply system, create or may create a danger to the health and well-being of the consumer.
