A
An Acre-foot (af) is a water measurement that equals
the amount of water one foot deep covering one flat acre of
land. 1 af = 325,851 gallons or 43,560 cu. ft of water.
An Active Management Area (AMA)
is a geographic area that has been designated pursuant to
A.R.S. §
45-411
as requiring active management of groundwater or, in the case
of the
Santa
Cruz active management area, active management of
any water, other than stored water, withdrawn from a well.
Subsequent active management areas may be designated through
local initiative or by the Director of the Department.
The
Adequate
Water Supply Program
requires anyone who offers subdivided land outside of an AMA
for sale or lease to obtain a determination from the State
regarding the availability of water supplies before the land
may be marketed to the public as defined in
R12-15-715 et
seq.
An Aquifer is a geologic formation that contains
sufficient saturated materials to be capable of yielding or
transmitting water in usable quantities to a well.
Area of Impact is the area where
stored water has migrated or is located (defined by a one-foot
rise in the water table), as projected on the land surface.
The area of impact for a
GSF
is the aerial extent of the service area of the Irrigation
District or other entity operating the GSF.
The
Assured
Water Supply Program
requires anyone who offers subdivided or unsubdivided land
inside an AMA for sale or lease to demonstrate an assured
supply of water to ADWR before the land may be marketed to the
public, as defined in R12-15-701 et seq.
C
Central Arizona Project (CAP )
Water
is Colorado River water delivered through the facilities of
the Central Arizona Project (CAP canals), and Plan 6 water.
To Convey a permit is to transfer the ownership of a
permit from one person to another.
D
Drawdown
is the lowering of the water table, caused by pumping water
from an aquifer.
E
Effluent
is water that has been collected in a sanitary sewer for
subsequent treatment in a facility that is regulated pursuant
to A.R.S. §§ 49-361 and 49-362.
G
Groundwater
is water under the surface of the earth regardless of the
geologic structure in which it is standing or moving.
I
An Impermeable Layer or Confining Formation is a
relatively solid geologic unit immediately overlying and/or
underlying an aquifer. Confining material often defines the
boundaries of an aquifer.
An Injection Well is a well constructed for the purpose
of introducing water directly into the aquifer.
In lieu Water
is water that is delivered by a water storer to a groundwater
savings facility (GSF) pursuant to permits issued under A.R.S.
§
45-812.01
and that is used in an active management area (AMA) or an
irrigation non-expansion area (INA )
by the recipient on a gallon-for-gallon substitute basis for
groundwater that otherwise would have been pumped from within
that AMA or INA.
An Irrigation Non-expansion Area (INA) is a geographic
area that has been designated pursuant to A.R.S. §
45-431 as
having insufficient groundwater to provide a reasonably safe
supply for the irrigation of the cultivated lands at the
current rate of withdrawal.
P
A Percolation Basin is a depressed area of land
designed to hold water while allowing that water to percolate
into the ground for the recharge of groundwater.
A
Permittee
is anyone who holds underground storage facility (USF),
groundwater savings facility (GSF), water storage (WS), or
recovery well (RW) permits.
Plan 6 Water
is surface water from any source conserved and developed
through dams and reservoirs in the Central Arizona Project and
lawfully delivered by the United States or a multi-county
conservation district.
R
Recharge
is the process of adding water to an aquifer. The process of
recharging water, when done pursuant to A.R.S. §
45-811.01
et seq., may result in accumulation of
long-term
storage credits
or the right to recover water. All recharge projects must be
permitted in order to accumulate storage credits and later
recover stored water (regardless of whether they are inside of
an AMA).
The Recoverable Amount is the amount of water stored,
as determined by the Director, minus losses for evaporation
and transpiration, as well as a percent credited to the
aquifer pursuant to A.R.S. §
45-852.01 ,
so long as the water was stored in accordance with A.R.S. §
45-801 et
seq.
Replenishment is the storage of water
or use of long-term storage credits by a groundwater
replenishment district, multi-county water conservation
district or an active management area water district to
fulfill their duties as described in Title
48 of
the Arizona Revised Statutes.
S
A Sanitary Sewer is any pipe or other enclosed conduit
that carries, among other substances, any water-carried wastes
from the human body from residences, commercial buildings,
industrial plants or institutions.
Stored Water
is water that is stored underground pursuant to a permit
issued under A.R.S. § 45-831.01. Generally, this is water that
cannot be used directly.
A Storer is a person who holds a water storage permit
pursuant to A.R.S. §
45-831.01 .
Subdivided Land
is land that is divided into six or more lots with at least
one lot comprising less than 36 acres.
Subsidence
is the settling or lowering of the land surface.
W
A Well is a man made opening in the earth through which
water may be withdrawn or obtained from beneath the surface of
the earth except as provided in A.R.S. § 45-591.01.
