[Amended 2-23-1987 by Ord. No. 87-3]
The purpose of these rules and regulations is:
A.
To protect the public water supply system from contamination or pollution
by isolating within the customer's water system contaminants or pollutants
which could backflow through the service connection into the public
water supply system.
B.
To promote the elimination or control of existing cross-connections,
actual or potential, between the public or consumer's potable water
system and nonpotable water systems, plumbing fixtures and sources
or systems containing substances of unknown or questionable safety.
C.
To provide for the maintenance of a continuing program of cross-connection
control which will prevent the contamination or pollution of the public
and consumer's potable water systems.
These rules and regulations shall apply to all premises served
by the public potable water supply system of the Village.
The owner or official custodian shall be responsible for protection of the public water supply system from contamination due to backflow or backsiphonage of contaminants through the customer's water service connection. If, in the judgment of the Superintendent or his authorized representative, an approved backflow prevention device is necessary for the safety of the public water supply system, the Superintendent shall give notice to the consumer to install such approved backflow prevention device at each service connection to the premises. The consumer shall immediately install such approved device or devices at his own expense; failure, refusal or inability on the part of the consumer to install such device or devices immediately shall constitute grounds for discontinuing water service to the premises until such device or devices have been installed. The consumer shall retain records of installation, maintenance, testing and repair as required in § 318-46D below for a period of at least five years. The Superintendent may require the consumer to submit a cross-connection inspection report to the Village to assist in determining whether or not service line protection will be required. All cross-connection inspections shall be conducted by a cross-connection control device inspector certified by the Illinois Environmental Protection Agency.
The following definitions shall apply in the interpretation
and enforcement of these regulations:
The Illinois Environmental Protection Agency.
Backflow prevention devices or methods approved by the Research
Foundation for Cross-Connection Control of the University of Southern
California, Association of State Sanitary Engineers, American Water
Works Association, American National Standards Institute or certified
by the National Sanitation Foundation.
Any water source or system on or available to the premises
other than the public water supply system and includes the water supplied
by the system. These auxiliary waters may include water from another
purveyor's public water supply system; or water from a source such
as wells, lakes, or streams or process fluids; or used water. These
waters may be polluted or contaminated or objectionable or constitute
a water source or system over which the water purveyor does not have
control.
The backflow of water or other liquids, mixtures, or substances
into the distribution pipes of a potable water system from any source
other than the intended source of the potable water supply.

premises supplied by or in any manner connected to a public water
system.
Any water system located on the customer's premises. A building
plumbing system is considered to be a customer's water system.

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.

joined to a source of unknown or unsafe substance.
An assembly composed of single, independently acting check
valves approved under ASSE Standard 1015; a double check valve assembly
and suitable connections for testing the water-tightness of each check
valve.
The unobstructed vertical distance through the free atmosphere
between the water discharge point and the flood level rim of the receptacle.
Any condition, device or practice in a water system or its
operation resulting from a real or potential danger to the health
and well-being of consumers. The word "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 significant reduction in the quality
of life.
A cross-connection through which an unknown substance can
be forced, drawn by vacuum or otherwise introduced into a safe potable
water system.

water for all purposes, including without limitation lawn sprinkler
systems, from the source of a private water supply on the premises
or from the main in the street, alley or at the curb to, within and
about any building or buildings where a person or persons live, work
or assemble. Plumbing includes all piping, from discharge of pumping
units to and including pressure tanks in water supply systems. Plumbing
includes all piping, fixtures, appurtenances, and appliances for a
building drain and a sanitary drainage and related ventilation system

so as to constitute a hazard or impair the usefulness of the water.
Water which meets the requirements of 35 Ill. Adm. Code 604
for drinking, culinary, and domestic purposes.
A fixture or appurtenance with threaded hose connection,
tapered spout, or other connection which would facilitate extension
of the water supply line beyond its legal termination point.
Any fluid or solution which may be chemically or 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 public or a consumer's potable water system. This includes,
but is not limited to:
Polluted or contaminated waters;
Process waters;
Used waters originating from the public water supply system
which may have deteriorated in sanitary quality;

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 closed shutoff valves located at each
end of the device, and each device shall be fitted with properly located
test cocks.

piping system regarding the location of all connections to the public
water supply 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 piping system. The survey
must be in written form, and should not be an actual plumbing inspection.
A condition through which an aesthetically objectionable
or degrading material not dangerous to health may enter the public
water supply system or a consumer's potable water system.

water system after it has passed through the service connection and
is no longer under the control of the water supply official custodian.

control devices within the consumer's premises.
B.
On request of the Superintendent, or his authorized representative,
the consumer shall furnish information regarding the piping system
or systems or water use within the customer's premises. The consumer's
premises shall be open at all reasonable times to the Superintendent
for the verification of information submitted by the inspection consumer
to the public water supply custodian regarding cross-connection inspection
results.
C.
It shall be the responsibility of the water consumer to arrange periodic
surveys of water use practices on his premises to determine whether
there are actual or potential cross-connections to his water system
through which contaminants or pollutants could backflow into his or
her public potable water system. All cross-connection control or other
plumbing inspections must be conducted in accordance with 225 ILCS
320/3.
