Editor's Note: Section 1 of this local law provided as follows: “The purpose of this local law is:
A. To protect the public potable water supply of the Highland Water District from the possibility of contamination by isolating within its customers' internal distribution system or its customers' private water system such contaminations or pollutants which could backflow into the public water supply system; and
B. To comply with the requirements of the New York State Sanitary Code 5-1.31.”
A. 
As used in this local law, the following terms shall have the meanings indicated:
AIR-GAP SEPARATION
A physical break between a supply pipe and 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 inch.
APPROVED CHECK VALVE
A check valve that seats readily and completely. It must be carefully machined to have free-moving parts and assured watertightness. The face of the closure element and valve seat must be bronze composition or other noncorrodible material which will seat tightly under all prevailing conditions of field use. Pins and bushings shall be bronze or other noncorrodible, nonsticking material, machined for easy, dependable operation. The closure element (e.g., clapper) shall be internally weighted or otherwise internally equipped to promote rapid and positive closure in all sizes where this feature is obtainable.
APPROVED DOUBLE-CHECK-VALVE ASSEMBLY
An 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 test cocks plus connections available for testing the watertightness of each check valve.
APPROVED REDUCED-PRESSURE-PRINCIPLE BACKFLOW PREVENTION DEVICE
A device incorporating two or more check valves and an automatically operating differential relief valve located between the two checks, two shutoff valves and equipped with necessary appurtenances for testing. The device shall operate to maintain the pressure in the zone between the two 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 valves shall be less than the supply pressure. In case of leakage of either valve, the differential relief valve shall operate to maintain this reduced pressure by discharging to the atmosphere. 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 submerged.
APPROVED WATER SUPPLY
Any water supply approved by or under the public health agency of the State of New York, the County of Ulster or the Highland Water District. In determining what constitutes an approved water supply, the Department of Public Health of the State of New York (herein called "State Health Department") shall have the final judgment as to its safety and potability.
AUXILIARY WATER SUPPLY
Any water supply on or available to the premises other than the district water supply.
COMMISSIONER
The Superintendent of the Highland Water District, or his authorized representatives.
CONSUMER
Any person to whom water is sold and furnished from the Highland Water District.
CONTAMINATION
An impairment of the quality of the district 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 OFFICER
The Ulster County Health Officer, his assistants or authorized deputies acting as or any other person appointed as Health Officer of the County of Ulster.
CROSS-CONNECTION
Any unprotected connection between any part of the district 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.
DISTRICT
The Highland Water District.
DISTRICT WATER SUPPLY
An approved water supply sold and delivered to consumers' premises through the waterworks system of the Highland Water District.
NONTOXIC SUBSTANCE
Any substance of a nonpoisonous nature that may create a moderate or minor hazard to the water supply system.
PERSON
Any natural person, firm association, organization, partnership, trust or association or 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.
PREMISES
Integrated land area, including improvements thereon. undivided by public thoroughfares or water distribution mains of the Highland Water District and where all parts of the premises are operated under the same management and for the same purpose.
PROTECTIVE DEVICE
Any of the following devices:
(1) 
Air-gap separation.
(2) 
Approved reduced-pressure-principle backflow prevention device.
(3) 
Approved double-check-valve assembly.
SERVICE CONNECTION
The terminal end of a service connection from the district water supply at 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.
TOXIC SUBSTANCE
Any substance (liquid, solid or gaseous), including raw sewage and lethal substances, that when introduced into the water supply system creates or may create a danger to the health and well-being of the consumer.
B. 
Word usage. "Shall" is mandatory; "may" is permissive.
A. 
Auxiliary water supply. Each service connection from the district water supply for furnishing water to premises having an auxiliary water supply shall be protected against backflow of water from the premises into the district water supply.
(1) 
If the auxiliary water supply is handled in a separate piping system with no known cross-connection, the district water supply shall be protected by an approved double-check-valve assembly installed at the service connection to the premises. When the auxiliary water supply may be contaminated, the Superintendent may order the district water supply protected by an air-gap separation or an approved reduced-pressure-principle backflow prevention device installed at the service connection.
(2) 
If the auxiliary water supply is handled in a separate piping system and cross-connections are known to exist between the district water supply and the auxiliary water supply which cannot presently be eliminated, the district water supply shall be protected by an approved reduced-pressure-principle backflow prevention device installed at the service connection to the premises. When the auxiliary supply may be contaminated, the Superintendent may order the district water supply protected by an air-gap separation installed at the service connection.
B. 
Toxic or hazardous substances. Should a facility be rated hazardous, a reduced-pressure-zone device would be required independent of a separate system handling the auxiliary water system. The district would also require a reduced-pressure-zone device if the facility were rated nonhazardous and the auxiliary water system did not meet the water quality requirements of Part 5 of the Sanitary Code.
C. 
Nonhazardous substances. At the service connection to any premises on which a substance that would be objectionable (but not necessarily hazardous to health) if introduced into the district water supply is handled in such a manner as to constitute a cross-connection, the district water supply shall be protected by an approved double-check-valve assembly.
D. 
Nonhazardous to hazardous. In the event that a facility is rated nonhazardous and on such a date becomes hazardous, notification of at least 30 days should be given to the Superintendent before the change takes place. Protection by the use of a protective device as required on hazardous substances must be installed.
E. 
Sewage treatment plant and pumping stations. At the service connection to any sewage treatment plan or sewage pumping station, the district water supply shall be protected by an air-gap separation. The air gap shall be located as close as practicable to the service connection and all piping between the service connection and receiving tank shall be entirely visible. If these conditions can not be reasonably met, the district water supply shall be protected with an approved reduced-pressure-principle backflow prevention device, provided that this alternative is acceptable to both the Superintendent and the County Health Officer. A final decision in this matter shall be made by the State Health Department.
F. 
Fire system. At the service connection to any premises in which a fire protection system is installed, the district water supply shall be protected based on the water source and arrangement of supplies in accordance with the following classifications:
(1) 
Class 1:
(a) 
Direct connection from public water mains only; no pumps tanks or reservoirs; no physical connections from auxiliary water supplies; no antifreeze or other additives of any kind; all sprinkler drains discharging to atmosphere, dry wells or other safe outlets.

(b) 
Protection: determined by the Superintendent upon review of engineering drawings of the system.
G. 
Lawn sprinkling systems. At the service connection to any permanently installed lawn sprinkling system, the district water supply shall be protected by an approved double-check-valve assembly. If the lawn sprinkling system handles liquid fertilizers or other chemicals, the district water supply shall be protected by an approved reduced-pressure-principle backflow prevention device.
A. 
Consumer responsibility. It shall be the responsibility of each consumer at his own expense to furnish, install and keep in good working order and safe condition any and all protective devices required in this local law. The district shall not be responsible for any loss or damage directly or indirectly resulting from or caused by the improper or negligent installation, operation, use, repair or maintenance of or interfering with, any protective service by any consumer or any other person.
B. 
Conflicts. Whenever two or more conditions exist on any premises for the correction of which different protective devices are required in this local law, the consumer shall be required only to install the protective device which, in the opinion of the Superintendent and County Health Officer, affords the maximum protection to the district water supply.
[Amended 8-21-2013 by L.L. No. 6-2013]
The consumer on whose premises any protective device is installed shall have each such device inspected annually. If successive inspections disclose repeated failures in the operation of any device, the Superintendent, Administrator or their designee or the designee of the Town of Lloyd Town Board, as Commissioners of the Highland Water District, may require more frequent inspections. Each device shall be repaired, overhauled or replaced at the expense of the consumer whenever it is found to be defective.
