New Franklin Where Protection Is Required ordinance (§ 700.110)

A. 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 Water Purveyor or the Missouri Department of Natural Resources, actual or potential hazards to the public potable water system exist. The type and degree of protection required shall be commensurate with the degree of hazard.

B. An approved air-gap separation or reduced pressure principle backflow prevention device shall be installed at the service connection or within any premises where, in the judgment of the Water Purveyor or the Missouri Department of Natural Resources, the nature and extent of activities on the premises or the materials used in connection with the activities or materials stored on the premises would present an immediate and dangerous hazard to health should a cross-connection occur, even though such cross-connection may not exist at the time the backflow prevention device is required to be installed. This includes, but is not limited to, the following situations:

1. Premises having an auxiliary water supply, unless the quality of the auxiliary supply is acceptable to the Water Purveyor and the Missouri Department of Natural Resources.

2. Premises having internal cross-connections that are not correctable or intricate plumbing arrangements which make it impractical to ascertain whether or not cross-connections exist.

3. Premises where entry is restricted so that inspection for cross-connections cannot be made with sufficient frequency or at sufficiently short notice to assure the cross-connections do not exist.

4. Premises having a repeated history of cross-connections being established or re-established.

5. Premises which, due to the nature of the enterprise therein, are subject to recurring modification or expansion.

6. Premises on which any substance is handled under pressure so as to permit entry into the public water supply or where a cross-connection could reasonably be expected to occur. This shall include the handling of process waters and cooling waters.

7. Premises where materials of a toxic or hazardous nature are handled such that if back siphonage or back pressure should occur, a serious health hazard may result.

C. The following types of facilities fall into one (1) or more of the categories of premises where an approved air-gap separation or reduced pressure principle backflow prevention device is required by the Water Purveyor and the Missouri Department of Natural Resources to protect the public water supply and must be installed at these facilities unless all hazardous or potentially hazardous conditions have been eliminated or corrected by other methods to the satisfaction of the Water Purveyor and the Missouri Department of Natural Resources:
