Unless otherwise expressly stated, for the purposes of this chapter, the following terms shall have the meanings indicated below. Words used in the present tense include the future. The singular number includes the plural, and the plural number includes the singular. The terms "shall" and "must" are mandatory and not optional.
APPROVEDA. The term "approved" as herein used in reference to a water supply shall mean a water supply that has been approved by the health agency having jurisdiction.
B. The term "approved" as herein used in reference to an air gap, a double check-valve assembly, a reduced-pressure principle backflow prevention assembly or other backflow prevention assemblies or methods shall mean approval by the administrative authority having jurisdiction.
AUXILIARY WATER SUPPLYAny water supply on or available to the premises other than the Woodstock Water District's approved public water supply will be considered an auxiliary water supply. These auxiliary waters may include water from a public potable water supply other than the Woodstock Water District or any natural source(s), such as a well, spring, river, stream, harbor, etc., or 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 Woodstock Water District does not have sanitary control.
BACKFLOWThe undesirable reversal of flow of water or mixtures of water and other liquids, gases or other substances into the pipes of the potable supply of water from any source or sources. See also "backsiphonage" and "backpressure."
BACKFLOW PREVENTERAn assembly, device or means designed to prevent backflow.
A. AIR GAPA physical separation between the free flowing discharge end of a potable water supply pipeline and an open or non-pressure-receiving 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 but in no case shall be less than one inch (2.54 centimeters).
B. REDUCED-PRESSURE PRINCIPLE BACKFLOW PREVENTION ASSEMBLYAn assembly containing two independently acting approved check valves together with a hydraulically operating, mechanically independent pressure differential relief valve located between the check valves and at the same time below the first check valve. The units shall include properly located resilient seated test cocks and tightly closing resilient seated shutoff valves at each end of the assembly. This assembly is designed to protect against a non-health hazard (i.e., pollutant) or a health hazard (i.e., contaminant). This assembly shall not be used for backflow protection of sewage or reclaimed water.
C. DOUBLE CHECK-VALVE BACKFLOW PREVENTION ASSEMBLYAn assembly composed of two independently acting, approved check valves, including tightly closing resilient seated shutoff valves attached at each end of the assembly and fitted with properly located resilient seated test cocks. This assembly shall only be used to protect against a non-health hazard (i.e., pollutant).
BACKPRESSUREAny elevation of pressure in the downstream piping system (by pump, elevation of piping, or steam and/or air pressure) above the supply pressure at the point of consideration which would cause, or have the potential to cause, a reversal of the normal direction of flow.
BACKSIPHONAGEA form of backflow due to a reduction in system pressure which causes a subatmospheric pressure to exist at a location in the water system.
CONSUMEROwner of a property which is served by the Woodstock Water District. Reference in this chapter to a consumer as herein defined shall include such consumer's duly authorized agent(s) or representative(s).
CONTAMINATIONAn impairment of the quality of water which creates an actual hazard to the public health through poisoning or through the spread of disease by sewage, industrial fluids, waste, etc.
CROSS-CONNECTIONAny unprotected actual or potential connection or structural arrangement between a public potable water system or a consumer's potable water system and any other source or system through which it is possible to introduce into any part of the potable water system any used water, industrial fluid, gas, or substance other than the intended potable water with which the system is supplied. Bypass arrangements, jumper connections, removable sections, swivel or changeover devices and other temporary or permanent devices through which or because of which backflow can or may occur are considered to be cross-connections.
CROSS-CONNECTION CONTROL BY CONTAINMENTThe appropriate type or method of backflow protection at the service connection commensurate with the degree of hazard of the consumer's potable water system.
CROSS-CONNECTION, CONTROLLEDA connection between a potable water system and a nonpotable water system with an approved backflow prevention assembly properly installed and maintained so that it will continuously afford protection commensurate with the degree of hazard.
DISTRICTThe Woodstock Water District, whose fiduciary officers are the Woodstock Town Board. Wherever it is referred to herein that permission be granted by, or that an application be made to, or that an act be done by, or that an act be approved by the District, it shall mean the Woodstock Water/Sewer Superintendent, unless such permission, application or act requires approval of the Woodstock Town Board pursuant to applicable laws of New York State.
HAZARD, DEGREE OFEither a pollution (non-health) hazard or contamination (health) hazard based upon evaluation of conditions within a water system.
HAZARD, HEALTHAn actual or potential threat of contamination of a physical or toxic nature to the public potable water system or the consumer's potable water system that would be a danger to the public health.
HAZARD, PLUMBINGAn internal or plumbing-type cross-connection in a consumer's potable water system that may be either a pollution (non-health) or a contamination (health) hazard. This includes but is not limited to cross-connections to toilets, sinks, lavatories, wash trays and lawn sprinkling systems. Plumbing-type cross-connections can be located in many types of structures, including homes, apartment houses, hotels and commercial or industrial establishments. An appropriate type of backflow prevention assembly, if permitted to exist, must properly protect such a connection.
HAZARD, POLLUTIONAn 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 not constitute a health or system hazard as defined herein. The maximum degree or intensity of pollution to which the potable water system could be degraded under this definition would cause a nuisance or be aesthetically objectionable or could cause minor damage to the water system or its appurtenances.
HAZARD, SYSTEMAn actual or potential threat of severe danger to the physical properties of the public or the consumer's potable water system or of pollution or contamination which would have a protracted effect on the quality of the potable water in the system.
INDUSTRIAL FLUIDSAny fluid or solution which may be chemically, biologically or otherwise contaminated or polluted in a form or concentration which 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 used waters; all types of process waters and used waters originating from the public potable water system which may deteriorate in sanitary quality; chemicals in fluid form; plating acids and alkalis; circulated cooling waters 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.; and oils, gases, glycerins, paraffins, caustic and acid solutions and other liquid and gaseous fluids used industrially for other processes or for fire-fighting purposes.
METERA device for measuring the volume of water used which only the Woodstock Water District may provide.
NYCRRNew York Codes, Rules and Regulations, the official compilation of codes, rules and regulations of New York State.
POLLUTIONAn impairment of the quality of the water to a degree that adversely and unreasonably affects the aesthetic qualities of such water for domestic use. See also "hazard, pollution."
SCHEDULE OF CHARGESThe Schedule of Charges for the Water District of the Town of Woodstock, Ulster County, New York, wherein are specified the current rents, fees, taxes, deposits, penalties and other bills and charges pertaining to the Woodstock Water District as established by resolution of the Woodstock Town Board.
SERVICE CONNECTIONThe terminal end of a service connection from the public potable water system, that is, where the Woodstock Water District may lose jurisdiction and sanitary control of the water at its point of delivery to the consumer's water system. If a water meter is installed at the end of the service connection, then the service connection shall mean the downstream end of the water meter.
TOWN BOARDThe Town Board of the Town of Woodstock, Ulster County, New York.
WATER, NONPOTABLEA water supply that has not been approved for human consumption by the health agency having jurisdiction.
WATER, POTABLEAny public potable water supply that has been investigated and approved by the health agency having jurisdiction. The system must be operating under a valid health permit.
