[Added by Ord. No. 06-01-87]
All users of the municipal water supply shall be required to
provide an effective means for protecting the public water supply
system from contamination due to backflow of contaminants through
the customer water service connection into the public water system.
A.
If, in accordance with the Illinois Plumbing Code or in the judgment
of the City of Mendota, an approved backflow prevention device is
necessary for the safety of the public water supply system, the Superintendent
of Water and Wastewater will give notice to the water customer to
install such an approved device immediately. The water customer shall,
at his own expense, install such an approved device at a location
and in a manner in accordance with the Illinois Plumbing Code and
all applicable local regulations, and shall have inspections and tests
made of such approved devices as required by the Illinois Plumbing
Code and local regulations.
B.
Only cross-connection control devices which are approved by the Foundation
for Cross-Connection Control and Hydraulic Research of the University
of Southern California, American Water Works Association, American
Society of Sanitary Engineering, or American National Standards Institute
or certified by the National Sanitation Foundation to be in compliance
with applicable industry specifications shall be used. Installation
of approved devices shall be made as specified by the manufacturer.
Maintenance as recommended by the manufacturer of the device shall
be performed. The manufacturer's maintenance manual shall be available
on-site.[1]
No person, firm or corporation shall establish or permit to
be established or maintain or permit to be maintained any connection
whereby a private, auxiliary or emergency water supply other than
the regular public water supply of the City of Mendota enters the
supply or distribution system of said municipality, unless such private,
auxiliary or emergency water supply and the method of connection and
use of such supply shall have been approved by the Superintendent
and the Illinois Environmental Protection Agency.
It shall be the duty of the Superintendent to cause surveys
and investigations to be made of industrial and other properties served
by the public water supply to determine whether actual or potential
hazards to the public water supply may exist. Such surveys and investigations
shall be made a matter of public record and shall be repeated at least
every two years, or as often as the Superintendent shall deem necessary.
Records of such surveys shall be maintained and available for review
for a period of at least five years.
The approved cross-connection control device inspector shall
have the right to enter at any reasonable time any property served
by a connection to the public water supply or distribution system
of the City of Mendota for the purposes of verifying the presence
or absence of cross-connections, and the Superintendent or his authorized
agent shall have the right to enter at any reasonable time any property
served by a connection to the public water supply or distribution
system of the City of Mendota for the purpose of verifying information
submitted by the customer regarding the required cross-connection
control inspection. On demand, the owner, lessees or occupants of
any property so served shall furnish to the Superintendent any information
which he may request regarding the piping system or systems or water
use on such property. The refusal of such information, when demanded,
shall, within the discretion of the Superintendent, be deemed evidence
of the presence of improper connections as provided in this article.
The Superintendent of the City of Mendota is hereby authorized
and directed to discontinue, after 10 days' written notice to the
occupant thereof, the water service to any property wherein any connection
in violation of the provisions of this article is known to exist,
and to take such other precautionary measures as he may deem necessary
to eliminate any danger of contamination of the public water supply
distribution mains. Water service to such property shall not be restored
until such conditions have been eliminated or corrected in compliance
with the provisions of this article, and until a reconnection fee
as set from time to time by the City Council is paid to the City of
Mendota. Immediate disconnection with verbal notice can be effected
when the Superintendent is assured that imminent danger of harmful
contamination of the public water supply system exists. Such action
shall be followed by written notification of the cause of disconnection.
The consumer responsible for backsiphoned material or contamination
through backflow, if contamination of the potable water supply occurs
through an illegal cross-connection or an improperly installed, maintained
or repaired device, or a device which has been bypassed, must bear
the cost of clean-up of the potable water supply system.
The Mayor and Council of the City of Mendota shall adopt such
regulations as they shall deem necessary to promote the elimination
or control of existing cross-connections in furtherance of this article.
A.
Purpose. The purposes of these rules and regulations are:
(1)
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.
(2)
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.
(3)
To provide for the maintenance of a continuing program of cross-connection
control which will prevent the contamination of pollution of the public
and consumer's potable water systems.
B.
Applicability. These rules and regulations shall apply to all premises
served by the public potable water supply system of the City of Mendota.
C.
Policy. The Mayor and Council 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 repairs as required in § 318-34D(4)
below for a period of at least five years.
The following definitions shall apply in the interpretation
and enforcement of these regulations:

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
