All technical industry words or phrases related to the irrigation
systems not specifically defined in this section shall have the meanings
customarily attributable in the irrigation industry. The following
words and terms, when used in this division, have the following meanings,
unless the context clearly indicates otherwise.
Air gap.
A complete physical separation between the free flowing discharge
end of a potable water supply pipeline and an open or non-pressure
receiving vessel.
Atmospheric vacuum breaker.
An assembly containing an air inlet value, a check seat,
and an air inlet port. The flow of water into the body causes the
air inlet valve to close the air inlet port. When the flow of water
stops the air inlet valve falls and forms a check against backsiphonage.
At the same time it opens the air inlet port allowing air to enter
and satisfy the vacuum. Also known as an atmospheric vacuum breaker
backsiphonage prevention assembly.
Automatic controller.
A solid state timer capable of operating valve stations to
set the days, time of day, and length of time water is applied.
Backflow prevention.
The mechanical prevention of reverse flow, or backsiphonage,
of non-potable water from an irrigation system into the potable water
source.
Backflow prevention assembly.

(r) Depth coverage of piping.
Piping in all irrigation systems
must be installed according to the manufacturer’s published
specifications for depth coverage of piping.
(1) If the manufacturer has not published specifications for depth coverage
of piping, the piping must be installed to provide minimum depth coverage
of six inches of select backfill for lateral lines and 12 inches for
main lines, between the top of the pipe and the natural grade of the
topsoil. All portions of the irrigation system that fail to meet this
standard must be noted on the irrigation plan. If the area being irrigated
has rock at a depth of six inches or less, select backfill may be
mounded over the pipe. Mounding must be noted on the irrigation plan
and discussed with the irrigation system owner or owner’s representative
to address any safety issues.
(2) If a utility, manmade structure or roots create an unavoidable obstacle,
which makes the six-inch depth coverage requirement impractical, the
piping shall be installed to provide a minimum of two inches of select
backfill between the top of the pipe and the natural grade of the
topsoil.

(t) Water contained within the piping of an irrigation system is deemed
to be nonpotable. No drinking or domestic water usage, such as, but
not limited to, filling swimming pools or decorative fountains, shall
be connected to an irrigation system. If a hose bib (an outdoor water
faucet that has hose threads on the spout) is connected to an irrigation
system for the purpose of providing supplemental water to an area,
