The purpose of this section is to protect the public health by controlling the actual or potential installation of cross connections. In the event that there is conflict between the technical publications adopted in this chapter or conflict between this section and the Uniform Plumbing Code, the building official shall determine the appropriate application Definitions. The following words and phrases, when used in this section, shall have the meaning ascribed in this section: Premises means real property, including any house or building thereon, located within the City and Borough. Purveyor means the operator or owner of a water supply. Unsafe facilities. The City and Borough of Juneau may refuse to furnish water and may discontinue services to any premises where plumbing facilities, appliances, or equipment using water are dangerous, unsafe, Page 8 of 12 UPC

9 or not in conformity with the water utility tariff or other related ordinances. No potable water service connection to any premises shall be installed or continued in use by a purveyor unless the potable water supply is protected by all necessary backflow prevention devices and assemblies. The installation or maintenance of a crossconnection, which will endanger the quality of the purveyor's water supply, shall be unlawful and is prohibited. Water supply means any system supplying water for domestic use, including source, treatment, storage, transmission and distribution facilities Cross connections. No water service shall be installed or continued in use by a purveyor unless the water supply is protected by all necessary backflow prevention devices. The installation or maintenance of a cross connection which will endanger the quality of the purveyor's water supply shall be unlawful and is prohibited. The control or elimination of cross connections shall be in accordance with this chapter and the current editions of the American Waterworks Association (AWWA) Pacific NW Cross-Connection Manual, 5/90 and Foundation for Cross-Connection Control and Hydraulic Research (FCCHR) Manual of Cross- Connection Control, 12/93, or such others as may from time to time be approved by the building official Possible cross connections. Backflow prevention devises shall be installed for any premises where, in the judgment of the building official, the nature and extent of activities, or the materials used or stored on the premises, could present a hazard to the water supply in the event a cross connection were to be made: even though such cross connection has not been made. Such circumstances include, but are not limited to: High Hazard application. The following facilities, when connected to a water supply, require backflow prevention devices at the service entry and at points of possible cross connections, unless the building official determines that lesser protection will suffice: Premises having intricate plumbing arrangements which make it impractical to ascertain whether or not cross connections exist; Premises where entry is restricted so that inspections for cross connections cannot be made with sufficient frequency or at sufficiently short notice to ensure that cross connections do not exist; Premises having a repeated history of cross connections being established or reestablished; Premises on which any substance is handled under pressure, so as to permit entry into the water supply. This shall include the handling of process waters and cooling waters; Premises where materials of a toxic or hazardous nature are handled in such a way that if backflow should occur a health hazard results; Hospitals, mortuaries and clinics; Laboratories; Metal plating industries; Water supplies for ships and boats; Page 9 of 12 UPC

10 Sewage treatment plants; Food or beverage processing plants; Chemical plants; Petroleum processing or storage plants; Radioactive material processing plants, nuclear reactors or other facilities where radioactive materials may be utilized; Manufacturing facilities; Car wash facilities; Water systems not within the definition of water supply; Medical / dental buildings; Laundries and dry cleaners; Sand, gravel and concrete plants or other material processing plants; Any direct connected water supply to a boiler heating system in which a toxic solution is used; Premises having an auxiliary water supply; and Other premises, systems or conditions presenting an imminent or grave danger to health Low hazard applications. The following facilities when connected to a water supply require backflow devices at the points of possible cross connections: Supply piping to fire sprinkler systems served by a water supply system; Irrigation systems; High rise or other buildings above system pressure which require booster pumps; Any direct connected water supply to a boiler heating water system in which only water is used as a heating medium; Other premises, systems or conditions presenting a possible or significant danger to health or which would adversely affect the taste, odor or appearance of water; Waterfront facilities; and Page 10 of 12 UPC

11 Piers and docks Backflow prevention devices The type or protective device required shall depend on the degree of hazard which exists as follows: High hazard. Only an air-gap separation or a reduced pressure principal backflow prevention device shall be installed unless specifically allowed in the FCCHR or AWWA cross connection control manuals or approved by the building official Low hazard. A double check valve assembly, pressure vacuum breaker, atmospheric vacuum breaker, non-testable double check valves with or without atmospheric ports, air-gap separation or a reduced pressure principal backflow prevention device shall be installed Backflow prevention devices shall be located so as to be readily accessible for maintenance and testing, and where no part of the device could be submerged or subject to freezing Backflow prevention devices required by this chapter shall be provided by the owner. The installation shall be inspected and approved by the building official Any protective device required by this chapter shall be a model approved by the building official. A double check value assembly, pressure vacuum breaker, or reduced pressure principal backflow prevention device will be approved if it has successfully passed both the laboratory and field evaluation tests of the University of Southern California Foundation of Cross-Connection Control and Hydraulic Research or other testing laboratory satisfactory to the building official The proper operation and maintenance of all backflow prevention devices shall be the responsibility of the owner. Whenever the devices are found to be defective, they shall be repaired, overhauled or replaced at the expense of the owner Cross connection inspection No water shall be delivered to any new structure constructed within the City and Borough until the same shall have been inspected by the building official for possible cross connections and been approved as being free of such cross connections No structure within the City and Borough may be connected or reconnected to any water system until the structure has been inspected by the building official for possible cross connections. Backflow prevention devices shall be installed on all possible cross connections prior to water system turn on Existing structures connected to any water system may be surveyed by the building official for possible cross connections. Backflow prevention devices shall be installed or upgraded on all high hazard and low hazard applications within 120 days of such survey, unless otherwise approved by the building official; provided, the installation of double check valve devices on existing sprinkler systems shall be completed within Page 11 of 12 UPC

12 one year from the date of survey Inspections may be made periodically of all potentially hazardous buildings, structures or improvements of any nature now receiving water through any water system, for the purpose of ascertaining whether cross connections exist. Such inspections will be made by the building official Any plumbing modification requiring a building permit shall require a cross connection inspection and compliance Reduced pressure principal and double check valve backflow prevention devices shall be inspected and tested at the time of installation and at intervals not exceeding one year. Inspections and tests shall be accomplished by testers certified by the building official, at the expense of the owner. Results of such tests shall be submitted to the building official Criminal liability. Any person who violates any provision of this section or who fails to comply with an order issued by the building official pursuant to this section is guilty of an infraction. Page 12 of 12 UPC
