(A) Upon written notice from the Mayor the water consumer receiving potable water service from the village shall install, at his sole expense, a backflow prevention assembly of a type approved by the Mayor. If the consumer fails to properly install such backflow prevention assembly within 90 calendar days after receiving written notice, water service shall be curtailed.
(B) In the case of emergency or condition deemed by the Mayor as being a potential hazard to the potable water supply, the Mayor may disconnect water service to the consumer immediately and such water service shall remain discontinued until such condition has been corrected and/or an approved backflow prevention assembly has been properly installed, inspected and certified.
(C) Such backflow assembly shall be inspected by a certified backflow inspector at least annually, or more often in those instances where successive inspections indicate possible defective operation. If repairs are deemed necessary by such inspector, such maintenance shall be performed within thirty calendar days unless division (B) hereof applies. All inspection, maintenance, repair and/or replacement costs are at the expense of the consumer. If a certified backflow inspector, not employed by the village, performs such inspection, it is the responsibility of the consumer to forward results of such inspections and testing results to the village for proper record keeping and use.
(D) An approved backflow prevention device shall be installed on each service line to a consumer's water system serving premises where, in the judgment of the Mayor, a health, pollutional or system hazard to the public water system exists. The cost of such backflow prevention device shall be at the expense of the owner and may be purchased directly by the owner. If requested by the owner, the device shall be furnished by the village and the cost shall be added to the taps, service line and meter fees and/or deposits.
(E) An approved backflow prevention device shall be installed on each service line to a consumer's water system serving premises where any of the following conditions exist:
(1) Premises having an auxiliary water system unless such auxiliary system is accepted as an additional source by the Mayor.
(2) Premises on which any substance is handled in such a fashion as to create an actual or potential hazard to the public water system. This shall include premises having sources or systems containing process fluids or waters originating from a public water system not under control of the Mayor.
(3) Premises having internal cross-connections that, in the judgment of the Mayor are not correctable, or intricate plumbing arrangements which make it impracticable to determine whether or not cross-connections exist.
(4) Premises where, because of security requirements or other prohibitions or restrictions, it is impossible or impractical to make a complete cross connection survey.
(5) Premises having a repeated history of cross-connections being established or reestablished.
(6) Others specified by the Mayor.
(F) An approved backflow prevention device shall be installed on each service line to a consumer's water system serving, but not necessarily limited to, the following types of facilities unless the Mayor determines that no health, pollutional or system hazard to the public system exists or potentially exists:
(1) Hospitals, mortuaries, clinics, funeral homes.
(2) Laboratories.
(3) Piers, docks, waterfront facilities.
(4) Sewage plants, sewage pumping stations or storm water pumping stations.
(5) Food or beverage processing plants.
(6) Chemical and fertilizer plants.
(7) Metal plating industries, metal fabricating plants, foundries.
(8) Petroleum processing or storage plants.
(9) Radioactive material processing plants or nuclear reactors.
(10) Electric generating plants.
(11) Car washes.
(12) Restaurants.
(G) An approved backflow prevention device shall be installed at any point of connection between the village's public potable water system and any auxiliary water system.
(H) The backflow protection device required shall depend on the degree of hazard as determined by the Mayor. In determining the degree of hazard and the type device to be required, the following criteria shall be used:
(1) An air gap separation is required where there are existing toxic substances on the premises in toxic concentration, and/or that may be handled in such a manner as to permit entry into the water system.
(2) An air gap separation or a reduced pressure principle backflow prevention device shall be used where there is an existing or potential health or system hazard.
(3) A double check valve assembly may be used at the discretion of the Mayor where there is an existing or potential pollutional hazard.
(I) Should an approved backflow prevention assembly be removed and/or bypassed, or if an unprotected cross-connection is found to exist on the premises, water service shall be discontinued until such conditions or defects are corrected and approved by the Mayor.
(J) The consumer shall allow the authority or its representatives, upon presentation of credentials of identification, to enter upon the premises of the consumer at all reasonable hours for the purpose of making surveys and investigations of the consumer's water system and water use practices.
(K) On request by the Mayor, the consumer shall furnish the village information on water use practices within the consumer's premises.
(L) Divisions (A) through (K) hereof do not relieve the consumer of the responsibility for conducting, or causing to be conducted, periodic surveys of water use practices on his premises to determine whether there are actual or potential cross-connections in the consumer's water system through which contaminants or pollutants could backflow into the public water system or a consumer's potable water system, nor does it relieve the consumer of any liability for damages incurred as a result of such cross connections.
(M) The Ohio EPA list of approved backflow prevention devices as amended from time to time is incorporated into this chapter by reference.
