(a) No person shall install or maintain a water service connection to any premises where actual or potential cross-connections to a public water system or a potable consumer's water system may exist unless such actual or potential cross connections are abated or controlled to the satisfaction of the Director of the Water Department.
(b) No person shall install or maintain any connection whereby water from an auxiliary water system may enter a public water system or potable consumer's water system unless the auxiliary water system and the method on connection and use of such system shall have been approved by the Director and by the Ohio E.P.A. as required by Ohio R.C. 6111.15.
(Ord. 91-1404. Passed 11-5-91.)
(a) The Director of the Water Department or his authorized representative, shall have the right to enter premises served by the public water system at all reasonable times for the purpose of making surveys and investigations of water use practices within the premises.
(b) On request by the Director or his authorized representative, the consumer shall furnish the water purveyor or his authorized representative information on water use practices within the customer's premises.
(c) Subsection (a) hereof does 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 a public water system.
(Ord. 91-1404. Passed 11-5-91.)
(a) An approved backflow prevention device shall be installed on each service line to a consumer's water system serving premises, where there is, in the judgment of the Director of the Water Department or the Ohio E.P.A., a real or potential health, pollution or system hazard to the public water system.
(b) An approved backflow prevention device shall be installed on each service line to a consumer's water system serving premises where the following conditions exists:

(2) Premises on which any substance is handled in such a fashion as to create an actual or potential hazard to a public water system. This shall include premises having sources or systems containing process fluids or waters originating from a public water system which are no longer under the control of the water purveyor;
(3) Premises having internal cross connections that, in the judgment of the Director, 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;

(1) An approved air gap separation shall be installed where a public water system may be contaminated with substances that could cause a severe health hazard.
(2) An approved air gap separation or an approved reduced pressure principle backflow prevention device shall be installed where a public water system may be contaminated with any substance that could cause a system or health hazard.
(3) An approved air gap separation or an approved reduced pressure principle backflow prevention device or an approved double check valve assembly shall be installed where a public water system may be polluted with any substance that could cause a pollution hazard.
(b) The type of protection required under Section 921.31(c) shall be an approved air gap separation or an approved interchangeable connection.
(c) Where an auxiliary water system is used as a secondary source of water for a fire protection system, the provisions of subsection (b) hereof for an approved air gap separation or an approved interchangeable connection may be waived by the Director of the Water Department and the Ohio E.P.A. provided:
(1) At premises where the auxiliary water system may be contaminated with substances that could cause a system or health hazard, a public water system or a potable consumer's water system shall be protected against backflow by installation of an approved reduced pressure principle backflow device.
(2) At all other premises, a public water system or a potable consumer's water system shall be protected against backflow by installation of either an approved reduced pressure principle backflow prevention device or an approved double check valve assembly.
(3) A public water system or a potable consumer's water system shall be the primary source of water for the fire protection system.
(4) The fire protection system shall be normally filled with water from a public water system or a potable consumer's water system.
(5) The water in the fire protection system shall be used for fire protection only, with no other use of water from the fire protection system downstream from the approved backflow prevention device.
(d) Types of Backflow Protection Required: Domestic Water Services.
(1) An approved backflow prevention device of the type designated shall be installed on each domestic water service connection to the following types of facilities unless the Director determines that no real or potential health, pollution or system hazard to the public water system exists. This list is presented as a guideline and should not be construed as being complete.
