computation of determining pressure losses and pressure requirements of an irrigation
system.
✔✔HYDRAULICALLY CONTROLLED - ✔✔A system which uses water pressure
through tubing to operate remote control valves.

pipe and tubing.
✔✔IPS - ✔✔Abbreviation for "Iron Pipe Size".
✔✔IRRIGATION INSPECTOR - ✔✔A person who inspects irrigation systems and
performs other enforcement duties for a municipality or water district as an employee or
as a contractor and is required to be licensed under Chapter 30.
✔✔IRRIGATION PLAN - ✔✔A scaled drawing of a landscape irrigation system which
lists required information, the scope of the project, and represents the changes made in
the installation of the irrigation system.
✔✔IRRIGATION SERVICES - ✔✔Selling, designing, installing, maintaining, altering,
repairing, servicing, permitting, providing consulting services regarding, or connecting
an irrigation system to a water supply.
✔✔IRRIGATION SYSTEM - ✔✔An assembly of component parts that is permanently
installed for the controlled distribution and conservation of water to irrigate any type of
landscape vegetation in any location, and/or to reduce dust or control erosion.
✔✔IRRIGATION TECHNICIAN - ✔✔A person who works under the supervision of a
licensed irrigator to install, maintain, alter, repair, service or supervise installation of an
irrigation system, including the connection of such system in or to a private or public,
, raw or potable water supply system or any water supply, and who is required to be
licensed under Chapter 30.
✔✔IRRIGATION ZONE - ✔✔A subdivision of an irrigation system with a matched
precipitation rate based on plant material type (such as turf, shrubs, or trees),
microclimate factors (such as sun/shade ratio), topographic features (such as slope)
and soil conditions (such as sand, loam, clay, or combination) or for hydrological
control.
✔✔IRRIGATOR - ✔✔A person who sells, designs, offers consultations regarding,
installs, maintains, alters, repairs, services or supervises the installation of an irrigation
system, including the connection of such system to a private or public, raw or potable
water supply system or any water supply, and who is required to be licensed under
Chapter 30.
✔✔IRRIGATOR-IN-CHARGE - ✔✔The irrigator responsible for all irrigation work
performed by an exempt business owner, including, but not limited to obtaining permits,
developing design plans, supervising the work of other irrigators or irrigation
technicians, and installing, selling, maintaining, altering, repairing, or servicing a
landscape irrigation system.
✔✔LATERAL PIPING - ✔✔Piping after the remote control valve not subject to constant
main line pressure.
✔✔LANDSCAPE IRRIGATION - ✔✔The science of applying the necessary amount of
water to promote or sustain healthy growth of plant material or turf.
✔✔LICENSE - ✔✔An occupational license that is issued by the commission under
Chapter 30 of this title to an individual that authorizes the individual to engage in an
activity that is covered by this chapter.
✔✔LOOPED MAIN LINE - ✔✔A main line designed to provide water to any valve from
two or more directions.
✔✔MAINLINE - ✔✔A pipe within an irrigation system that delivers water from the water
source to the individual zone valves.
✔✔MAINTENANCE CHECKLIST - ✔✔A document made available to the irrigation
system's owner or owner's representative that contains information regarding the
operation and maintenance of the irrigation system, including, but not limited to:
checking and repairing the irrigation system, setting the automatic controller, checking
the rain or moisture sensor, cleaning filters, pruning grass and plants away from
irrigation emitters, using and operating the irrigation system, the precipitation rates of
each irrigation zone within the system, any water conservation measures currently in
effect from the water purveyor, the name of the water purveyor, a suggested seasonal
