13.06.110 Definitions.
“Approved air gap” means a physical separation between the free flowing end of a potable water supply pipeline and the overflow rim of an open or nonpressurized receiving vessel. To be an air gap approved by the DOH, the separation must be at least:
A. Twice the diameter of the supply piping measured vertically from the overflow rim of the receiving vessel, and in no case be less than one inch, when unaffected by vertical surfaces (sidewalls); and
B. Three times the diameter of the supply piping, if the horizontal distance between the supply pipe and a vertical surface (sidewall) is less than or equal to three times the diameter of the supply pipe, or if the horizontal distance between the supply pipe and intersecting vertical surfaces (sidewalls) is less than or equal to four times the diameter of the supply pipe and in no case less than one and one-half inches.
“Approved atmospheric vacuum breaker” means an atmospheric vacuum breaker of make, model, and size that is approved by the DOH. Atmospheric vacuum breakers that appear on the current approved backflow prevention assemblies list developed by the University of Southern California Foundation for Cross-Connection Control and Hydraulic Research, or that are listed, or approved by other nationally recognized testing agencies (such as the International Association of Plumbing and Mechanical Officials, American National Standards Institute, or Underwriter Laboratories) and acceptable to the local administrative authority are considered approved by the DOH.
“Approved backflow preventer” means an approved air gap, an approved backflow prevention assembly, or an approved atmospheric vacuum breaker, relied upon by the purveyor for the protection of the public water system. The requirements of WAC 246-290-490 do not apply to backflow preventers installed for other purposes.
“Approved backflow prevention assembly” means a reduced pressure backflow assembly, reduced pressure detector assembly, double check valve assembly, double check detector assembly, pressure vacuum breaker assembly, or spill resistant vacuum breaker assembly, of make, model, and size that is approved by the DOH. Assemblies that appear on the current approved backflow prevention assemblies list developed by the University of Southern California Foundation for Cross-Connection Control and Hydraulic Research, or other nationally recognized testing agencies and acceptable to the local administrative authority are considered approved by the DOH.
“Auxiliary water supply” means a water supply, other than the purveyor’s water supply, on or available to the consumer’s premises.
“Backflow” means the undesirable reversal of flow of water or other substances through a cross-connection into the public water system or consumer’s potable water system by means of backpressure or backsiphonage.
“Backpressure” means a pressure (caused by a pump, elevated tank or piping, boiler, or other means) on the consumer’s side of the service connection that is greater than the pressure provided by the public water system and which may cause backflow.
“Backsiphonage” means backflow due to a reduction in system pressure in the purveyor’s distribution system and/or the consumer’s water system.
“Consumer” means any person receiving water from a point of delivery of the public water system. For purposes of cross-connection control, “consumer” means the owner or operator of a premises receiving water from a point on delivery of the public water system.
“Consumer’s water system,” as used in WAC 246-290-490, means any potable and/or industrial water system that begins at a point of delivery from the public water system and is located on the consumer’s premises. The consumer’s water system includes all auxiliary sources of supply, storage, treatment, and distribution facilities, piping, plumbing, and fixtures under the control of the consumer.
“Contaminant” means a substance present in drinking water that may adversely affect the health of the consumer or the aesthetic qualities of the water.
“Cross-connection” means any actual or potential physical connection between a public water system or the consumer’s water system and any source of nonpotable liquid, solid, or gas that could contaminate the potable water supply by backflow.
“Cross-connection control program” means the administrative and technical procedures the water purveyor implements to protect the public water system from contamination via cross-connections as required in WAC 246-290-490.
“Cross-connection control specialist” means a person holding a valid cross-connection control specialist certificate issued by DOH in accordance with Chapter 246-292 WAC.
“Director” means Director of Public Works or duly authorized representative.
“DOH” means the Washington State Department of Health or health officer as identified in a joint plan of operation in accordance with WAC 246-290-030(1).
“High health cross-connection hazard” means a cross-connection that could impair the quality of potable water and create an actual public health hazard through poisoning or spread of disease by a contaminant source.
“Human consumption” means the use of water for drinking, bathing or showering, hand washing, food preparation, cooking, or oral hygiene.
“In-premises protection” means a method of protecting the health of consumers served by the consumer’s potable water system, located within the property lines of the consumer’s premises by the installation of an approved air gap or approved backflow prevention assembly at the point of hazard, which is generally a plumbing fixture.
“Local administrative authority” means the local official, board, department, or agency authorized to administer and enforce the provisions of the Uniform Plumbing Code as adopted under Chapter 19.27 RCW.
“Low health cross-connection hazard” means a cross-connection that could cause an impairment of the quality of potable water to a degree that does not create a hazard to the public health, but does adversely and unreasonably affect the aesthetic qualities of such potable waters.
“Point of delivery” means the point at which the consumer’s water system connects to the public water system.
“Potable” means water suitable for human consumption.
“Premises” means a single building site, or single lot or aggregation of lots tied together by agreement for the purpose of obtaining a building permit or utility service.
“Premises isolation” means a method of protecting a public water system by installation of approved air gap or approved backflow prevention assembly at or near the service connection or alternative location acceptable to the purveyor to isolate the consumer’s water system from the purveyor’s distribution system.
“Public water system” means the water supply source, including all water treatment, storage, transmission and distribution facilities, to the point of delivery to the consumer.
“Purveyor” means the City of Ferndale, owner and operator of the public water system.
“Service connection” means the point of delivery from which potable water is provided to a single-family residence, or other residential or nonresidential population.
“State Board of Health” and “Board” means the board created by RCW 43.20.030.
“Uniform Plumbing Code” means the code adopted under RCW 19.27.031(4) and amended under Chapter 51-46 WAC. This code establishes statewide minimum plumbing standards applicable within the property lines of the consumer’s premises.
“Used water” means water that has left the control of the purveyor. (Ord. 1416 § 1, 2006)
