The following definitions apply when the following words or phrases are used in this chapter, whether or not these words or phrases are capitalized:
Approved.Used in reference to a backflow preventer or any method, device, or assembly to prevent a backflow condition or cross-connection means approval by the Director or a Cross-Connection Control Officer.
Auxiliary Water Supply.Any unapproved water supply located on the premises of a water user that is not received from a public water system. Examples are wells, ponds, lakes, streams, rivers, and untreated water reservoirs.
City's Water System.All facilities of the City of Santa Barbara for the production, storage, treatment, distribution, or delivery of potable water from any source.
Consumer.The owner or operator of an on-site water system receiving service from a public water system.
Contamination or Contaminant.An impairment of the quality of the water that creates an actual hazard to the public health through poisoning or through the spread of disease by sewage, industrial fluids, or waste.
Degree of Hazard.Either pollutant (non-health) or contaminant (health) hazard and is derived from the evaluation of conditions within the system.
Double Check Detector Backflow Prevention Assembly (DCDA).A specially designed assembly composed of a line-size approved double check valve assembly with a bypass containing a specific water meter and an approved double check valve assembly. The meter shall register accurately for only very low rates of flow up to two gallons per minute (GPM) and shall show a registration for all rates of flow. This assembly shall only be used to protect against a non-health hazard (i.e., pollutant). The DCDA is primarily used on fire sprinkler systems.
Double Check Valve Backflow Prevention Assembly (DC).An assembly composed of two independently acting, approved check valves that include tightly closing, resilient seated shutoff valves attached at each end of the assembly and fitted with properly located resilient seated test cocks. This assembly shall only be used against a nonhealth hazard (i.e., pollutant).
Health Agency.The California State Department of Health Services (DHS) or the Santa Barbara County Department of Environmental Health Services (DEH).
Pollution or Pollutant.An impairment of the quality of the water to a degree that does not create a hazard to the public health, but that does adversely and unreasonably affect the aesthetic qualities of such waters for domestic use.
Reduced-Pressure Principle Backflow Prevention Assembly.An assembly containing two independently acting, approved check valves together with a hydraulically operating, mechanically independent, pressure differential relief valve located between the check valves and, at the same time, below the first check valve. The unit shall include properly located resilient seated test cocks and tightly closing resilient seated shut-off valves at each end of the assembly. This assembly is used to protect against a non-health (pollutant) or a health (contaminant) hazard.
Reduced-Pressure Principle Detector Backflow Prevention Assembly (RPDA).A specially designed assembly composed of a line-size approved reduced-pressure principle backflow prevention assembly with a bypass containing a specific water meter and an approved reduced-pressure principle backflow prevention assembly. The meter shall register for only very low rates of flow up to two GPM and shall show a registration for all rates of flow. This assembly shall be used to protect against a non-health (pollutant) or a health (contaminant) hazard. The RPDA is primarily used on fire sprinkler systems.
Service Connection.The delivery point between a public water system and a customer's potable water service pipeline. Generally, the service connection will be at the property line where a customer's potable water service pipeline connects to a City meter. If unmetered service is authorized, the service connection is generally the closest point on the customer's property to where the customer's potable water service pipeline connects to a public water system.
Service Protection.The appropriate type or method of backflow protection or cross-connection protection commensurate with the degree of hazard to the public water system or the consumer's potable water system.
Site Supervisor.A person designated by a customer who has the responsibility for the avoidance of backflow or cross-connections during the installation, operation and maintenance of the customer's pipelines and related equipment.
Water Purveyor.The operator of a public water system supplying an approved water supply to the public.
