This article shall apply to all consumers of the City’s public water supply system.
A. The public water supply system shall be designed, installed and maintained in such a manner as to prevent contamination through cross connections or piping connections to the public water supply system.
B. Cross connections are prohibited, except as approved by the City’s authorized representative. No cross connection shall be installed or maintained whereby an auxiliary water supply system may enter a public water supply system.
C. If, in the judgment of the City’s authorized representative, cross connection protection is required through either piping modification or installation of an approved backflow prevention device, due and appropriate notice shall be given to the consumer. The consumer shall be given a reasonable amount of time to provide the required protection, at the consumer’s expense. Failure or refusal to provide such protection shall constitute grounds for disconnection to the public water supply system until such time as protection has been provided.
A. An approved backflow prevention device must be installed on each service line to a consumer’s water system serving a premises where there is actual or potential cross connection.
B. An approved air gap separation or RPZ must be installed at the service connection or within any premises where, in the judgment of the City’s authorized representative, the nature or extent of activities on the premises, or the materials used in connection with the activities or materials stored on the premises, may present contamination of the public water supply system from a cross connection.
C. Examples of situations where air gap separation or RPZ must be installed may include, but are not limited to, the following facilities or situations:
1. Premises having an auxiliary water supply.
2. Premises having internal plumbing arrangements which make it impractical to ascertain whether or not a cross connection exists.
3. Premises where entry is restricted so that inspection for cross connections cannot be made with sufficient frequency or at sufficiently short notice to ensure that cross connections do not exist.
4. Premises having a previous history of cross connections being established or reestablished.
5. Premises which, due to the nature of the enterprise therein, are subject to recurring modifications or expansion.
6. Premises on which any substance is handled under pressure so as to permit entry into the public water supply system, or where a cross connection could reasonably be expected to occur. This shall include the handling process waters and cooling waters.
