[Ord. 909, 7/13/1995,
§ 2]
APPROVED BACKFLOW ASSEMBLY
Accepted by the State Department of Health, Allegheny County
Health Department, as meeting an applicable specification or as suitable
for the proposed use.
AUXILIARY WATER SUPPLY
Any water supply on or available to the premises other than
the purveyor's public water supply will be considered as an auxiliary
water supply. These auxiliary waters may include water from another
purveyor's public potable water supply 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 water purveyor does not have authority for sanitary
control.
BACK-PRESSURE
The flow of water or other liquids, mixtures or substances
under pressure into the feeding distribution pipes of a potable water
supply system from any source(s) other than the intended source.
BACKSIPHONAGE
The flow of water or other liquids, mixtures or substances
into the distribution pipes of a potable water supply system from
any source(s) other than the intended source, caused by the reduction
of pressure in the potable water supply system.
BACKFLOW
The reversal of the normal flow of water caused by either
back-pressure or backsiphonage.
BACKFLOW PREVENTION ASSEMBLY
An assembly or means designed to prevent backflow. Specifications
for backflow prevention assemblies are contained within the Local
Plumbing Code and the Backflow Prevention Program approved by the
state.
CONTAMINATION
A degradation of the quality of the potable water supply
by sewage, industrial fluids or waste liquids, compounds or other
materials.
CROSS CONNECTION
Any physical connection or arrangement of piping or fixtures
which may allow nonpotable water or industrial fluids or other material
of questionable quality to come in contact with potable water inside
a distribution system. This would include any temporary connections,
such as swing connections, removable sections, four way plug valves,
spools, dummy section of pipe, swivel or change-over devices or sliding
multiport tubes or other plumbing arrangement.
CROSS CONNECTION-CONTAINMENT
The installation of an approved backflow assembly at the
water service connection to any customer's premises where it
is physically and economically infeasible to find and permanently
eliminate or control all actual or potential cross connections within
the customer's water system; or, it shall mean the installation
of an approved backflow prevention assembly on the service line leading
to and supplying a portion of a customer's water system where
there are actual or potential cross connections which cannot be effectively
eliminated or controlled at the point of the cross connection (isolation).
CROSS CONNECTION-CONTROLLED
A.
A 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 the protection
commensurate with the degree of hazard.
B.
Whenever the public water purveyor deems a service connection's
water usage contributes a sufficient hazard to the water supply, an
approved backflow prevention assembly shall be installed on the service
line of the identified consumer's water system, at or near the
property line, or immediately inside the building being served; but,
in all cases, before the first branch line leading off the service
line. The type of protective assembly required shall depend upon the
degree of hazard which exists at the point of cross connection (whether
direct or indirect), applicable to local and state requirements or
resulting from the required survey. All presently installed backflow
prevention assemblies which do not meet the requirements of this section
but were approved assemblies for the purposes described herein at
the time of installation and which have been properly maintained shall,
except for the inspection and maintenance requirements be excluded
from the requirements of these rules so long as the water purveyor
is assured that they will satisfactorily protect the public water
system. Whenever the existing assembly is moved from the present location
or, requires more than the minimum maintenance or, when the water
purveyor finds that the operation or maintenance of this assembly
constitutes a hazard to health, the unit shall be replaced by an approved
backflow prevention assembly meeting the local and state requirements.
It shall be the responsibility of the consumer at any premises where
backflow prevention assemblies are installed to have certified surveys/inspections,
and operational tests made at least once per year at the consumer's
expense. In those instances where the Public Water Purveyor deems
the hazard to be great, he may require certified surveys/inspections
and tests at a more frequent interval. It shall be the duty of the
public water purveyor to see that these tests are made according to
the standards set forth by the State Department of Health, Allegheny
County Health Department.
WATER PURVEYOR
The person designated to be in charge of the Water Department
of the Borough of Aspinwall is invested with the authority and responsibility
for the implementation of an effective backflow prevention program
and for the enforcement of the provisions of this Part.
[Ord. 909, 7/13/1995,
