Efficient irrigation is geared more directly toward: a. manufactures, irrigation contractors, homeowners, and proper education
a. manufactures, irrigation contractors, homeowners, and
proper education
b. federal government
c. city government
d. state government
Manufactures can impact water conservation by producing: b. better low-volume irrigation products
a. products at a lower cost
b. better low-volume irrigation products
c. sizing components properly
d. more efficient irrigation scheduling
Which of the following is not a basic principle of c. sizing components
Xeriscaping:
a. mulching
b. efficient irrigation
c. sizing components
d. proper maintenance
,Pressure compensating devices help save water because c. help eliminate misting or fogging at the sprinkler heads

The art and management of applying water to the a. landscape irrigation
landscape to encourage the growth of plant material and
support water conservation is:
a. landscape irrigation
b. an irrigation system
c. an irrigation design
d. good for business and the environment
the rate (or speed) at which soil will accept water. The absorption rate
speed at which water can penetrate or infiltrate the soil.
Also called percolation or infiltration rate. As the soil
"capacity" is reached, the absorption rate will decrease. It
is affected by soil type, slope, run-off, etc. Different soil
types absorb water at a different rate.
the depth of soil in which a plant extracts most of the water active root zone
it needs for evapotranspiration
The operating pressure measured at the base of a Actual head pressure
sprinkler head. Actual head pressure is calculated by
deducting total pressure losses from the static water
pressure. ---- has to be equal to, or greater than, the
minimum head pressure, for a given sprinkler head to
function correctly
An approved ---- is the unobstructed vertical distance Air Gap
through free atmosphere between the lowest pint of water
supply outlet and the flood level rim of the fixture or
assembly into which the outlet discharges. There vertical,
physical separations must be at least twice the diameter of
the water supply outlet, but never less than 1 in.
Small device used on some subsurface drop irrigation that Air/Vacuum Relief Valve
allows air into the dripperline when the system is not
running which eliminates any vacuum that could result in
debris or contaminants being sucked into the piping
system
The amount of water, in irrigation management, that is Allowable Depletion (AD)
allowed to be depleted from the plant available water
before an irrigation event is scheduled. Also referred to as
Managed Allowable Depletion (MAD). Generally, 50%
depletion is the rule of thumb
, An electric current that reverses it direction periodically Alternating Current (AC)
Any device that introduces air into the system to prevent Anti-Siphon Device
"back siphonage."
Rate at which water is applied by sprinkler heads in a Application rate
certain pattern. Usually measured in inches per hour,
gallons per hour or gallons per day. Commonly called
"precipitation rate".
What are the three methods in which to evaluate 1. a densogram
application rates? 2. Precipitation rate formula
96.3 x total GPM / total area
3. a water audit
An underground layer or porous rock, sand, etc. containing Aquifer
water, into which wells can be sunk
The surface area of the landscape to which a sprinkler Arc
head will provide water. Usually described in degrees or
part of a full circle head. The degrees of coverage of a
sprinkler from one side of a pattern to the other.
Scale expressing foot measurements in parts of an inch Architect Scale
A corrected or redrawn plan showing the "actual scaled" As-Built Plan
location of all major components of the system and other
information the property owner might require. An ---- is an
individual tool form irrigators to locate major components
at a later date
A back flow prevention device that allows air into the piping Atmospheric Vacuum Breaker (AVB)
system, with the use of a float that moves up and down, to
prevent backsiphonage. No back pressure can exist for
proper operation. It cannot be under constant pressure for
more than 12 hours in any 24- hour period. This device
must be installed vertically and a minimum of 6' higher
than all down stream piping and the highest downstream
head or outlet. There cannot be any shut off valves
downstream of the ---. A separate --- must be installed on
the discharge side of each control valve, between the
valve and all emission devices.
An electrical or hydraulic control valve in a sprinkler Automatic Control Valve
system which is activated by an automatic controller. Also
called a section valve, circuit valve, zone valve, remote
control valve, electrical valve, or hydraulic valve
An irrigation system which will automatically cycle (water) Automatic System
according to a preset program
Water (measured in inch of water per inch of soil) that is Available Water
actually accessible for the plant to use
