Auxiliary water supply means any water supply on, or available to, a facility other than the county's water system, which is not permitted by the Florida Department of Environmental Protection and over which the county does not have sanitary control. Auxiliary water supplies may include water from another public water supply, any natural source such as a well, spring, river, stream, harbor or used water, reclaimed water, irrigation quality (IQ) water, or industrial fluids.

Backflow means a reversal of the normal direction of flow, which has the potential to introduce used water or mixtures of used water and other liquids, gases or other substances into the county's public water system from a source or sources. Backflow may occur as the result of back-pressure, back-siphonage or both.

Back-pressure means any elevation of pressure in the downstream piping system caused by a pump, elevated tank, boiler, or other means that could create pressure within that system, greater than the supply pressure of the county's water system which, would cause, or tend to cause, a reversal of the normal direction of flow.
