VILLAGE WATER SUPPLY
For the purpose of this article, unless it is plainly evident from
the context that a different meaning is intended, certain terms used
herein are defined as follows:
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.
A check valve that seats readily and completely. It must
be carefully machined to have free-moving parts and assured water-tightness.
The face of the closure element and valve seat must be bronze, composition
or other noncorrodible material which will seat lightly 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.
An assembly of at least two independently acting approved
check valves, including tightly closing shutoff valves on each side
of the check valves assembly and suitable test cocks, plus connections
available for testing the water-tightness of each check valve.
A devise 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.
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 Wappingers Falls. 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.
Any water supply on or available to the premises other than
the Village water supply.
The Superintendent of Water of the Village of Wappingers
Falls or his authorized representatives.
Any person to whom water is sold and furnished from the Village
of Wappingers Falls.
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.
The Dutchess County Health Officer, his assistants or authorized
deputies acting as, or any other person appointed as, Health Officer
of the County of Dutchess.
Any unprotected connection in any part of the Village waterworks
system used or intended to supply water for drinking purposes and
any source or system containing water or a substance that is not or
cannot be approved as safe, wholesome and potable for human consumption.
Any substance of a nonpoisonous nature that may create a
moderate or minor hazard to the water supply system.
Any 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 Dutchess, any special purpose district and any officer or agent
thereof.
Integrated land area, including improvements thereon, undivided
by public thoroughfares or water distribution mains of the Village
of Wappingers Falls and where all parts of the premises are operated
under the same management and for the same purpose.
Any of the following devices:
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.
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.
The Village of Wappingers Falls.
An approved water supply sold and delivered to consumers'
premises through the waterworks system of the Village of Wappingers
Falls.
B.
As used in this article, the word "shall" is mandatory; the word
"may" is permissive.
A.
Auxiliary water supply. Each service connection from the Village
water supply for furnishing water to premises having an auxiliary
water supply shall be protected against backflow of water from the
premises into the Village water supply.
(1)
If the auxiliary water supply is handled in a separate piping system
with no known cross-connection, the Village water supply shall be
protected by an approved double-check valve assembly installed at
the service connection to the premises.
(2)
When the auxiliary water supply may be contaminated, the Superintendent
may order the Village water supply protected by an air gap separation
or an approved reduced-pressure-principle flow prevention device installed
at the service connection.
(3)
If the auxiliary water supply is handled in a separate piping system
and cross-connections are known to exist between the Village water
supply and the auxiliary supply which cannot presently be eliminated,
the Village water supply shall be protected by an approved reduced-pressure-principle
flow prevention device installed at the service.
B.
Toxic or hazardous substance. Should a facility be rated hazardous
(as determined by the Board of Water Commissioners), a reduced pressure
zone device would be required independent of a separate system handling
the auxiliary water system. The Village 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 (as determined by the Board of Water Commissioners),
if introduced into the Village water supply, is handled in such a
manner as to constitute a cross-connection, the Village water supply
shall be protected by an approved double-check valve assembly.
D.
Nonhazardous to hazardous. In the event a facility is rated nonhazardous
and on such a date becomes hazardous, notification of at least 30
days shall 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 station. At the service connection
to any sewage treatment plant or sewage pumping stations, the Village
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 receiving tank shall
be entirely visible. If these conditions cannot be reasonably met,
the Village 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 Village 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: double-check valve assembly if not already installed
in the system.
[Amended 1-13-2016 by L.L. No. 1-2016]
(4)
Class 4.
(5)
Class 5.
(a)
Directly supplied from public mains and interconnected with
auxiliary supplies, such as pumps taking suctioning from services
exposed to contamination or rivers and ponds; driven wells; mills
or other industrial water systems; or where antifreeze or other additives
are used.
(b)
Protection: air gap or reduced-pressure-principle backflow prevention
device.
G.
Lawn-sprinkling systems. At the service connection to any permanently
installed lawn-sprinkling system, the Village water supply shall be
protected by an approved double-check valve assembly. If the lawn-sprinkling
system handles liquid fertilizers or other chemicals, the Village
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
article. The Village 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 article, 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 Village
water supply.
A.
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 requested inspections.
B.
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 thereof, the consumer fails to have any of the inspections made as required herein or to make the above-described records available, the consumer shall pay the fee shown in the schedule, said fee shall be deemed a lawful charge and subject to the terms of § 148-19 of this chapter.
A.
No water service connection shall be installed on the premises of
any consumer unless the Village water supply is protected as required
by this article.
B.
Delivery of water to the premises of any consumer may be discontinued
by the Superintendent if any protective device required by this article
has not been installed, inspected, tested, and maintained or is defective
or has been removed or bypassed.
C.
Delivery.
(1)
Delivery of water shall be discontinued immediately and without notice
to the consumer if the Superintendent or County Health Office determines
that:
(2)
Delivery of water shall not be resumed until any protective device
by this article and approved by the Superintendent has been properly
installed or until conditions at the consumer's premises causing the
contamination danger or contamination have been abated or corrected
to the satisfaction of the Superintendent and County Health Officer.
D.
Notice.
(1)
Except as provided in Subsection C, delivery of water shall not be discontinued until written notice thereof has been given to the consumer. The notice shall state:
(a)
The conditions or defects which must be corrected;
(b)
The manner in which the stated conditions or defects are to
be corrected; and
(c)
The date on or after which delivery of water will be discontinued
and which shall not be fewer than 15 nor more than 90 days following
the date of delivery of mailing of the notice. The Superintendent
may grant the consumer an extension of an additional period not to
exceed 90 days if he determines the consumer has exercised due diligence
but has been unable to comply with the notice within the time originally
allowed.
(2)
The notice shall be given by delivering the same to the consumer,
the manager or agent thereof or to any person in charge of or employed
in the place of business of the consumer; of, if the consumer has
no place of business, then at the place of residence of the consumer,
if known, or by leaving the notice at either the place of business
or residence of the consumer. If the consumer cannot be found, service
of the notice shall be mailed, postage fully prepaid, addressed to
the consumer at the place of business or residence set forth in the
application of the consumer for water service in the records of the
Village.
(3)
Once discontinued, delivery of water shall not be resumed until any
protection device required by this article and approved by the Superintendent
has been properly installed or until the conditions at the consumer's
premises creating the need for a protective device have been abated
or corrected to the satisfaction of the Superintendent and the County
Health Officer.
E.
For the purposes of making any inspections or discharging the duties
imposed by this article, the Superintendent and County Health Officer
shall have the right to enter upon the premises of any consumer. Each
consumer, as a condition of the continued delivery to this premises
of water from the Village water supply, shall be considered as having
stated his consent to the entry upon his premises of the Superintendent
and County Health Officer for the purposes stated herein.
All presently installed prevention devices which do not meet the requirements of this section 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 § 148-37, 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 moved from the present location requires more than minimum maintenance which constitutes a hazard to health, the unit shall be replaced by a backflow prevention device meeting the requirement of this article.
