(a) Cross Connection Control; General Policy.
(1) Purpose. The purpose of these rules and regulations is:
A. To protect the public potable water supply from contamination or pollution by isolating within the consumer's water system contaminants or pollutants which could backflow through the service connection into the public potable water system.
B. To promote the elimination or control of existing cross-connection, actual or potential, between the public or consumer's potable water system and non-potable water systems. Plumbing fixtures and sources or systems containing process fluids.
C. To provide for the maintenance of a continuing program of cross-connection control which will systematically and effectively prevent the contamination or pollution of the public and consumer's potable water systems.
(2) Application. These rules and regulations shall apply to all premises served by the public potable water system of the Village of Enon.
(3) Policy. The supplier of water shall be responsible for protection of the public potable water system from contamination due to backflow of contaminants through the water service connection. If, in the judgment of the supplier of water or his authorized representative a backflow prevention device is needed they shall give notice to the consumer to install such approved backflow prevention device at each service connection to his premises. The consumer shall immediately install such approved device or devices at his own expense, and 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.
(b) Definitions. The following definitions shall apply in the interpretation and enforcement of these rules and regulations:

(16) "Non-potable water" means water not safe for drinking, personal, or culinary use.
(17) "Person" means the state, any political subdivision, public or private corporation, individual, partnership, or other legal entity.
(18) "Pollution" means the presence in water of any foreign substance that lands to degrade its quality so as to constitute a hazard or impair the usefulness or quality of the water to a degree which does not create an actual hazard to the public health but which does adversely and unreasonably affect such waters for domestic use.
(19) "Potable water" means which is satisfactory for drinking, culinary, and domestic purposes and meets the requirements of the Ohio EPA.
(20) "Process fluids" means any fluid or solution which 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 public or a potable consumer's water system.

This shall include premises having sources or systems containing process fluids or waters originating from the public potable water system which are no longer under the sanitary control of the supplier of water.
C. Premises having internal cross-connections that, in the judgment of the supplier of water are not correctible or intricate plumbing arrangements which make it impractical to determine whether or not cross-connections exist.
D. Premises where, because of security requirements or other prohibitions or restrictions, it is impossible or impractical to make a complete cross-connection survey.
E. Premises having a repeated history of cross-connections being established or re-established.

(k) Booster Pumps.
(1) Where 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 ten pounds per square inch gage or less.
(2) It shall be the duty of the water consumer to maintain the low pressure cut-off device in proper working order and to certify to the supplier of water at least once a year, that the device is operable.
(l) Violations.
(1) The supplier of water shall deny or discontinue, after reasonable notice to the occupants thereof, the water service to any premises where any backflow prevention device required by these regulations is not installed, tested and maintained in a manner acceptable to the supplier of water or if it is found that the backflow prevention device has been removed or by-passed, or if an unprotected cross-connection exists on the premises, or if a low pressure cut-off required by these regulations is not installed and maintained in working order.
