Unless otherwise expressly stated or the context clearly indicates
a different intention, the following terms shall, for the purpose
of this article, have the meanings indicated in this section:
AGENCY
The Illinois Environmental Protection Agency.
APPROVED
Those backflow prevention devices or methods approved by
the Research Foundation for Cross-Connection Control of the University
of Southern California, the American Water Works Association, the
American Society of Sanitary Engineering, the American National Standards
Institute, or certified by the National Sanitation Foundation.
AUXILIARY WATER SUPPLY
Any water source or system on or available to any premises,
other than the waterworks system, and includes the water so supplied.
These auxiliary waters may include water from a public water supply
system; or water from a private or emergency water supply system;
or water from a source such as wells, lakes, or streams; or process
fluids; or used water. Auxiliary waters may be polluted or contaminated
or objectionable or constitute a water supply system over which the
Village does not have control.
BACKFLOW
The flow of water or other liquids, mixtures, or substances
into the distribution pipes of a potable water supply system from
any source other than the intended source of the potable water supply
system.
BACKSIPHONAGE
A type of backflow in a pipe or plumbing device in which
used, contaminated, or polluted water flows back from a receptacle
or other source into a negative pressure in such pipe or plumbing
device.
CONTAMINATION
An impairment of the quality of the waterworks system or
other potable water supply system by entrance of any substance to
a degree that could create a health hazard.
CROSS-CONNECTION
Any physical connection or arrangement between two otherwise
separate piping systems, one of which contains potable water and the
other a substance of unknown or questionable safety or quality, whereby
there may be a flow from one system into the other. A direct cross-connection
is a cross-connection formed when the waterworks system or other potable
water supply system is physically joined to a source of unknown or
unsafe substance. An indirect cross-connection is a cross-connection
through which an unknown substance can be forced, drawn by a vacuum
or otherwise introduced into the waterworks system or other water
supply system.
CROSS-CONNECTION CONTROL DEVICE
Any approved device, method, or type of construction intended
to prevent backflow into the waterworks system or other potable water
supply system. The term "backflow prevention device" shall be included
in the definition of "cross-connection control device." All devices
used for backflow prevention in Illinois must meet the standards of
the Illinois Plumbing Code and the Agency.
CUSTOMER
The owner, occupant, and/or person in possession, charge,
or control of any premises.
CUSTOMER'S WATER SYSTEM
Includes all parts of the water facilities beginning at the
service connection used to convey water from the waterworks system
to the premises, which facilities are deemed to be operated, controlled,
or owned by the customer.
DOUBLE CHECK VALVE ASSEMBLY
An assembly composed of single, independently acting check
valves approved under ASSE Standard 1015. A double check valve assembly
must include tight shutoff valves located at each end of the assembly
and suitable connections for testing the watertightness of each check
valve.
FIXED AIR GAP
The unobstructed vertical distance through the free atmosphere
between the lowest opening from any pipe or faucet supplying water
and the flood level rim of the receptacle.
HEALTH HAZARD
Any condition, device, or practice in a water system or its
operation resulting in a real or potential danger to a person's health
and well-being. The term "severe" as used to qualify "health hazard"
means a hazard to the health of the user that could be expected to
result in death or a significant reduction in the quality of life.
INSPECTION
A plumbing inspection to examine carefully and critically
all materials, fixtures, piping and appurtenances, appliances, and
installations of a plumbing system for compliance with the requirements
of the Illinois Plumbing Code and this article.
NONPOTABLE
The quality of water that does not meet public health standards
for drinking water and is not suitable for human consumption.
POLLUTION
The presence of any foreign substance (organic, inorganic,
radiological, or biological) in water that tends to degrade its quality
so as to constitute a hazard or impair the usefulness of the water.
POTABLE
The quality of water that meets public health standards for
drinking water and is suitable for human consumption.
PREMISES
Includes any lot or part of a lot, any building or part of
a building, or any parcel or tract of land whatsoever.
PROCESS FLUIDS
Any fluid or solution that may be chemically, biologically,
or otherwise contaminated or polluted in a form or concentration such
as would constitute a health, pollutional, or system hazard if introduced
into the waterworks system, a customer's water system, or any other
potable water supply system. This includes, but is not limited to:
A.
Polluted or contaminated water.
B.
Used water originating from the waterworks system which may
have deteriorated in sanitary quality.
C.
Contaminated natural water taken from wells, lakes, streams,
or irrigation systems.
D.
Chemicals in solution or suspension.
E.
Oils, gases, acids, alkalis and other liquid and gaseous fluids
used in industrial or other processes, or for fire-fighting purposes.
REDUCED PRESSURE PRINCIPLE BACKFLOW PREVENTION DEVICE
A device containing a minimum of two independently acting
check valves together with an automatically operated pressure differential
relief valve located between the two check valves and approved under
ASSE Standard 1013. During normal flow and at the cessation of normal
flow, the pressure between these two checks shall be less than the
supply pressure. In case of leakage of either check valve, the differential
relief valve, by discharging to the atmosphere, shall operate to maintain
the pressure between the check valves at less than the supply pressure.
The unit must include tightly closing shutoff valves located at each
end of the device, and each device shall be fitted with properly located
test cocks.
SERVICE CONNECTION
The opening, including all fittings and appurtenances, at
a water main of the waterworks system through which water is supplied
to the customer.
SURVEY
The collection of information regarding the location of all
connections between a customer's water system and the waterworks system
and must include the location, type, and most recent inspection and
testing date of all cross-connection control devices and methods located
within that customer's premises. The survey must be in written form,
and should not be an actual plumbing inspection.
USED WATER
Any water supplied by the waterworks system after it has
passed through the service connection and is no longer under the control
of the Village.
VILLAGE
The Village of Bannockburn.
WATER FUND
The monies or revenues of every kind arising by the operation of this Part
2 or any other ordinance relating to the waterworks system.
WATER SUPPLY SYSTEM
Any water source, supply, or system, including all pipes,
fittings, and control valves, as well as the water so supplied. The
term "water supply system" shall not include the waterworks system,
however.
WATERWORKS SYSTEM
Includes the entire system of pipes, hydrants, boxes, cocks,
taps, meters, connections, reservoirs, tanks, engines, property, and
all appurtenances thereto, whereby water is or may be supplied to
the public or to private parties within the Village, which system
is operated, controlled, or owned by the Village. The term "water
service system" shall be included in the definition of waterworks
system.
No private supply pipe shall be laid or connection made thereto
by any person other than a duly licensed and bonded plumber acting
under authority of a permit issued for the laying of such private
supply pipe or connection therewith or thereto as provided for in
this article.
Subpart J of the Illinois Plumbing Code is hereby adopted hereto
and by this reference incorporated herein and made a part hereof.
When a booster pump has been installed on the service line to
or within any premises, such pump shall be equipped with a low-pressure
cut-off device designed to shut off the booster pump when the pressure
in the service line on the suction side of the pump drops to 20 psi
or less. It shall be the duty of the customer to maintain the low-pressure
cut-off device in proper working order and to certify to the Water
Commissioner, at least once a year, that the device is operable.
