The purpose of this article is to:
A. Protect the public potable water supply of the Village of Millbrook
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. Comply with the requirements of the New York State Sanitary Code
5-1.31.
For the purpose of this chapter, unless it is plainly evident
from the context that a different meaning is intended, certain terms
used herein are defined as follows:
AIR GAP SEPARATION
A 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 inch.
APPROVED CHECK VALVE
A check valve that seals readily and completely. It must
be carefully machined to have free-moving parts and assured watertightness.
The face of the closure element and valve seal must be bronze, composition
or other noncorrodible material which will seal 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 water tightness 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 supervision
of a public health agency of the State of New York, the County of
Dutchess or the Village of Millbrook. In determining what constitutes
an approved water supply, the Department of Health of the State of
New York (herein called "State Health Department") shall have the
final judgment as to its safety and potability.
CONSUMER
Any person to whom water is sold and furnished from the Village
of Millbrook.
CONTAMINATION
An impairment of the quality of the Village 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 Dutchess County Health Officer, the officer's assistants
or authorized deputies acting as, or any other person appointed as,
Health Officer of the County of Dutchess.
CROSS CONNECTION
Any unprotected connection between any part of the Village
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 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 Dutchess, any special purpose district and any officer or agent
thereof.
PREMISES
Integrated land and including improvements thereon undivided
by public thoroughfares or water distribution mains of the Village
of Millbrook 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:
B.
Approved reduced pressure principle backflow prevention device.
C.
Approved double check valve assembly.
SERVICE CONNECTION
The terminal end of a service connection from the Village
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.
SUPERINTENDENT
The Superintendent of Water of the Village of Millbrook or
his or her authorized representatives.
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.
VILLAGE WATER SUPPLY
An approved water supply sold and delivered to consumers'
premises through the waterworks system of the Village of Millbrook.
Shall is mandatory; may is permissive.
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
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. Records of such test, repairs and overhauls
shall be kept, and a copy of such records forwarded to the Superintendent
on an annual basis. The Superintendent shall have the duty of determining
that the inspections required herein are performed properly. If, following
demand therefor, the consumer fails to have any of the inspections
made as required herein or to make the above-described records available,
the Superintendent shall have the right to inspect the device, and
the consumer shall pay the cost thereof.
All presently installed prevention devices which do not meet the requirements of this chapter but were approved devices for the purposes described herein at the time of installation and which have been properly maintained shall, except for the inspection and maintenance requirements under §
180-61, be excluded from the requirements of these rules so long as the Superintendent is assured that they will satisfactorily protect the Village's water supply. Whenever the existing device is moved from the present location, requires more than minimum maintenance or which constitutes a hazard to health, the unit shall be replaced by a backflow Protective Device meeting the requirements of this chapter.
Any person, firm or corporation who or which violates any of the provisions of this article shall, upon conviction, be punishable as provided in Chapter
1, General Provisions, Article
III.
