The following rules and regulations pertaining to cross-connection control shall be implemented by the Village of Palos Park:
(a) General Policy.
(1) Purpose. The purposes of these rules and regulations are:
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 the consumer's potable water system and non-potable 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 the consumer's potable water systems.
(2) Application. These rules and regulations shall apply to all premises served by the public potable water supply system of the Village of Palos Park.
(3) 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 Commissioner of Buildings/Superintendent of Water or his or her authorized representative, an approved backflow prevention device is necessary for the safety of the public water supply system, the Commissioner of Buildings/Superintendent of Water shall give notice to the consumer to install such an approved backflow prevention device at each service connection to the premises. The consumer shall immediately install such an approved device or devices at his or her own expense. Failure, refusal or inability on the part of the consumer to install such a 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 subsection (f) hereof for a period of at least five years. The Commissioner of Buildings/Superintendent of Water may require the consumer to submit a cross-connection inspection report to the Village of Palos Park to assist in determining whether or not service line protection will be required.
