Section 7.46.030 - Definitions
In addition to the definitions outlined in CCR Title 17, the following terms are defined for the purpose of this chapter:

Approved Backflow Device: Refers to the list of the backflow prevention devices listed in Section 7.46.030 (H)1-5.

Approved Water Supply: The term “Approved Water Supply” shall mean a water supply whose potability is regulated by the Department of Health Services.

Auxiliary Water Supply: The term “Auxiliary Water Supply” shall mean any water supply, other than the City's, which is either on or available to the property. Auxiliary Water Supply may include water from another public potable water supply or from any natural source(s) such as, but not limited to, a well, a river, a stream, or used water. These waters may be contaminated, polluted, or constitute an unacceptable water source over which the City does not have sanitary control.

Backflow: The term "Backflow" shall mean the undesirable reversal of flow of water or mixtures of water and other liquids, gasses, or substances into the distribution pipes of the City's potable water supply from any source or sources.

Backpressure: The term "Backpressure" shall mean any elevation of water supply pressure which could cause, or tends to cause, a reversal of the normal direction of water flow.

Backsiphonage: The term "Backsiphonage" shall mean the flow of water or other liquids, mixtures or substances into the distribution pipes of a potable water supply system from any source other than its intended source caused by negative or sub atmospheric pressure in the potable water supply system.

Backflow Preventer: The term “Backflow Preventer” shall mean an installed device designed to ensure water can only flow in one direction in order to prevent a reverse flow created by a difference in water pressure.

Backflow Prevention Device(s): The term “Backflow Prevention Device(s)” shall mean the different backflow prevention devices and assembly methods acceptable for use in the City. These are as follows:

Air Gap (AG): The term "Air Gap" shall mean a physical separation between the free flowing discharge end of a potable water supply pipeline and an open or non-pressure receiving vessel.

2. Reduced Pressure Principle Backflow Prevention Assembly (“RPP Assembly”): The term "RPP Assembly" shall mean 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. The unit shall include properly located resilient seated test cocks and tightly closing resilient seated shutoff valves at each end of the assembly.

Double Check Valve Backflow Prevention Assembly (“DC Assembly”): The term “DC Assembly” shall mean an assembly composed of two independently acting approved check valves, including tightly closing resilient seated shutoff valves attached at each end of the assembly and fitted with properly situated resilient seated test cocks.

Double Check Detector Assembly (“DCDA Assembly”): The term “DCDA Assembly” shall mean an assembly composed of a line-size approved double check valve with a bypass containing a specific water meter and an approved double check valve. The meter shall accurately register flow rates of up to two (2) gallons per minute (gpm) and shall show a registration of all flow rates.

Pressure Vacuum Breaker Assembly (“PVB Assembly”): The term “PVB Assembly” shall mean an assembly composed of a spring-loaded check valve, spring-loaded air inlet valve, test cocks, and two shut-off valves.

Contamination: The term “Contamination” shall mean an impairment of the quality of the water, creating a public health hazard through poisoning or through the spread of disease by bacteria, virus, sewage, industrial fluids, or other toxic substances.

Cross-Connection: The term “Cross-Connection” shall mean any actual or potential connection or structural arrangement between a public water system, including a piping system connected to the public water system located on the premises of a Water User or available to the Water User, and any source or distribution system containing liquid, gas, or other substances not from an approved water supply. Bypass arrangements, jumper connections, removable sections, swivel or change over devices, or other devices through which backflow could occur, shall be considered to be Cross-Connections.

Cross-Connection Controlled: The term “Cross-Connections Controlled” shall mean a connection between a potable and non-potable water system with an approved backflow prevention assembly properly installed and maintained in order to continuously afford the proper protection.

Types of Hazards. The types of hazards causing a particular level of damage in regards to health, plumbing, pollution, and/or potable water systems, in order of severity, are classified as follows:

Health Hazard: The term "Health Hazard" shall mean the actual or potential threat of contamination of a physical or toxic nature to the City's water system or the Water User's potable water system that would be a danger to the public’s health.

Plumbing Hazard: The term "Plumbing Hazard" shall mean an internal or plumbing type cross-connection in a Water User's potable water system that may be to a pollutant or contaminant. This includes, but is not limited to, cross-connections to toilets, sinks, lavatories, wash basins, swimming pool plumbing systems, and lawn sprinkler systems. If permitted to exist, this hazard must be properly protected by an appropriate type of backflow prevention assembly.

Pollution Hazard: The term “Pollution Hazard” shall mean the actual or potential threat to the physical properties or the potability of the water system which would not constitute a health or system hazard. The potable water system would be degraded, depending on the degree or intensity of pollution, to the point where it becomes a nuisance, is aesthetically objectionable, or causes minor damage to the system or its appurtenances.

System Hazard: The term “System Hazard” shall mean an actual or potential threat of severe danger to the physical properties of the City's or the Water User's potable water system, which could have a delayed effect on the quality of the potable water in the system.

Industrial Fluids: The term “Industrial Fluids” shall mean any fluid or solution which may be toxic, or chemically, biologically, or otherwise contaminated or polluted in a form or concentration which would constitute a health, a system, a pollution, or a plumbing hazard if introduced into an approved water supply system.

Pollution: The term “Pollution” shall mean an impairment of the water quality to a degree that does not create a public health hazard but does adversely affect the aesthetic qualities of such water for domestic use.

Potential: The term “Potential” shall mean having or showing the capacity to become or develop into something in the future.

Service Connection: The term "Service Connection" shall mean the downstream end of the water meter. This is the point of delivery to the Water User's water system where the City loses jurisdiction and sanitary control of the water.

User Supervisor: The term “User Supervisor” shall mean a person designated by a Water User to oversee a water use site and who is responsible for preventing cross-connections.

Potable Water: The term "Potable Water" shall mean any public or private water supply that has been investigated and approved for human consumption.
