Types of Recharge Permits
A person who wishes to store, save,
replenish, or recover water through the recharge program must
apply
for permits
through ADWR. Depending on what the applicant intends to
accomplish, up to three types of ADWR permits may be required.

Project Recharge Basins (SRP) |
Facility Permits
An Underground Storage Facility (USF) Permit (A.R.S.
§
45-811.01  )
allows the permit holder to operate a facility that stores
water in the aquifer. The criteria a USF must meet in order
to be permitted include:
1.
The project must be hydrologically feasible;
2.
The applicant must demonstrate financial and technical
capability;
3.
The applicant must agree in writing to obtain any required
floodplain use permit from the county flood control district
before beginning any construction activities;
4.
The project may not cause unreasonable harm to land or other
water users within the area of impact; and
5.
The project will continue to be monitored to ensure storage
does not cause the migration of poor quality water.
A Constructed Underground Storage Facility Permit allows for
water to be stored in an aquifer by using some type of
constructed device, such as an injection well or percolation
basin.
A Managed Underground Storage Facility Permit allows for water
to be discharged to a naturally water-transmissive area such
as a streambed that allows the water to percolate into the
aquifer without the assistance of a constructed device. All
surface flows entering and exiting a managed underground
storage facility must be measured at the facility boundaries
in a manner consistent with the Department’s measuring device
rules (R12-15-905
& 906 ).

A Groundwater Savings Facility (GSF) Permit (A.R.S.
§
45-812.01 )
allows the permit holder to deliver a renewable water supply,
called "in-lieu" water, to a recipient who agrees to replace
groundwater pumping with in lieu water, thus creating a
groundwater savings. The recipient must agree in writing
that for every gallon of in lieu water received, the recipient
will reduce groundwater withdrawals from within an Active
Management Area (AMA)
or Irrigation Non-expansion Area (INA)
by one gallon. Information regarding the criteria a facility
must meet in order to be permitted as a GSF is included in
A.R.S. § 45-812.01.
Water
Storage Permits
A Water Storage (WS) Permit (A.R.S. §
45-831.01) allows
the permit holder to store water at a USF or GSF. In order to
store water, the applicant must provide to the Department
evidence of its legal right to the source water proposed for
recharge. A contract for
CAP water
must be submitted to the Department prior to storing CAP water
obtained pursuant to that contract. Water storage must occur
at a permitted facility. For further requirements, see A.R.S.
§§ 45-831.01 &
45-852.01 .

Recovery Well Permits
A Recovery Well (RW) Permit (A.R.S. §
45-834.01)
allows
the permit holder to recover long-term storage credits or
to recover stored water annually. The impact of recovering
stored water in the proposed location must not damage other
land and water users, as noted in the adopted well spacing
and impact rules (R12-15-1301-1308). An impact analysis
is required under certain circumstances.
