Regulations" to read as follows :
"Section 12-106 . CROSS-CONNECTION CONTROL REGULATIONS.
1 . GENERAL POLICY:
(A) Purpose: The purpose of these rules and regulations is :
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 non-potable 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
or pollution of the public and consumer's potable water
systems .
(B) Application: These rules and regulations shall apply to all
premises served by the public potable water supply system of
the village.
(C) Policy: The owner or official custodian shall be responsible
for protection of the public water supply system from
contamination due to backflow or back-siphonage of
contaminants through the customer's water service connection.
If, in the judgment of the Public Works Superintendent or his
authorized representative, an approved backflow prevention
device is necessary for the safety of the public water supply
system, the Public Works 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
installa- tion, maintenance, testing and repair as required
in subsection 1 . (D) below for a period of at least five (5)
years . The Public Works Superintendent may require the
consumer to submit a cross-connection inspection report to
the Village Water Department 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.
2 . DEFINITIONS :
(A) The following definitions shall apply in the interpretation
and enforcement of these regulations:
