A well which was drilled before June 12, 1980 and which is not abandoned or sealed or a well which was not completed on June 12, 1980 but for which a Notice of Intent to Drill was on file with the Arizona Water Commission on such date. A.R.S. § 45-591(1).

This is a well drilled in search of geophysical, mineralogical or geotechnical data. A.A.C. R12-15-801(13).

Turf acres that came into existence or were substantially commenced after December 31, 1984 and before January 1, 1992, but that was not substantially commenced prior to January 1, 1985.

An artesian well in which the pressure is sufficient to cause the water to rise above the land surface. A.A.C. R12-15-801(14).

General industrial use permits are permits issued pursuant to A.R.S. § 45-515 for the withdrawal of groundwater from a point outside of the exterior boundaries of the service area of a city, town or private water company for a general industrial use located outside of the exterior boundaries of such service area.  A “general industrial use” means a non-irrigation use of groundwater except uses subject to dewatering permits and mineral extraction and metallurgical processing permits, as well as uses for which a certificate of assured water supply is required.  General industrial use includes animal industry use.  See A.R.S. § 45-515 for other requirements and restrictions on general industrial use permits.

An area which, as nearly as known facts permit as determined by the director pursuant to this chapter, may be designated so as to enclose a relatively hydrologically distinct body or related bodies of groundwater, which shall be described horizontally by surface description. A.R.S. § 45-402(13).

A system of pipes, canals or other works within a municipal provider’s service area which are owned and operated by the provider to collect, store, treat or deliver groundwater for non-irrigation use, regardless of whether other types of water are also present in the system.

Groundwater withdrawn from outside AMA and INA boundaries can be restricted in terms of its transportation between groundwater basins but is generally subject only to the requirement “for reasonable and beneficial use.” A.R.S. § 45-453. Community water systems outside of AMAs and INAs have the additional requirement to submit annual water use reports to ADWR.

The Arizona State Supreme Court has ruled that landowners do not own the groundwater beneath their property, but rather have the right to withdraw those waters. The Court stated in Town of Chino Valley vs City of Prescott, “In the absolute sense, there can be no ownership in seeping and percolating waters until they are reduced to actual possession and control by the person claiming them because of their migratory character. Like wild animals free to roam as they please, they are the property of no one.”

Outside of the AMAs and INAs, ADWR has no statutory authority to regulate the impact of one landowner’s pumping on their neighbor’s unless groundwater is being transferred between basins or sub- basins. ADWR can investigate and inspect wells to ensure that they are properly constructed and that the associated well records are accurate A.R.S. § 45-633(A).

"Groundwater savings facility" means a facility that meets the requirements of section 45-812.01 in an active management area or an irrigation non-expansion area at which groundwater withdrawals are eliminated or reduced by recipients who use in lieu water on a gallon-for-gallon substitute basis for groundwater that otherwise would have been pumped from within that active management area or irrigation non-expansion area.

Non-exempt wells drilled within any of the five AMAs require a groundwater withdrawal authority to be issued a drill card. Some examples of a groundwater withdrawal authority include:

Service Area Right

• Ex: City of Phoenix, City of Tucson, City of Prescott

Irrigation Grandfathered Right

• Used for irrigation. The right to be irrigated stays with the land, rather than with the owner.

Non-Irrigation Grandfathered Right

• Type 1: Used for non-irrigation. Examples include dairy farms and golf courses. This right stays with the land.
• Type 2: This right is the same as a Type 1, but it stays with the owner. It can be used anywhere in the AMA it was issued and can also be bought and sold. There are a limited number of Type 2 Rights.

General Industrial Use Permit

Groundwater rights can be viewed using this map. For more information about Groundwater Withdrawal Authorities please contact the AMA section at 602-771-8585.

This is a permit issued to withdraw groundwater in an AMA for a specific use that is authorized under A.R.S. Title 45, Chapter 2, Article 7. Authorized groundwater uses that require groundwater withdrawal permits include dewatering, temporary dewatering, emergency temporary dewatering, mineral extraction and metallurgical processing, general industrial use, poor quality groundwater, drainage water withdrawal, temporary electrical generation and hydrologic testing.

Upon receipt of an application to drill a new non-exempt well within an AMA, a hydrologic study (impact analysis) will be conducted by hydrology staff to confirm it meets well spacing and well impact rules pursuant to A.R.S. § 45-598(A).

Cement mixed with no more than 50% sand by volume and containing no more than six gallons of water per 94 lb. sack of cement. A.A.C. R12-15-801(15).

The extraction of minerals using acid solutions applied to metallic ores that have been removed from their original location and heaped or dumped in a new location.

A group of rooms or a single room occupied as separate living quarters. Housing unit includes a single family home, a patio home, a townhouse, a condominium, an apartment, a permanently set-up mobile home or a unit in a multifamily complex. Housing unit does not include a mobile home in an overnight or limited-stay mobile home park or a unit in a campground, motel, hotel or other temporary lodging facility. A housing unit may be occupied by a family, a family and unrelated persons living together, two or more unrelated persons living together, or by one person.

"In lieu water" means water that is delivered by a storer to a groundwater savings facility pursuant to permits issued under this chapter and that is used in an active management area or an irrigation non-expansion area by the recipient on a gallon-for-gallon substitute basis for groundwater that otherwise would have been pumped from within that active management area or irrigation non-expansion area.

The extraction of metallic ores using acid leaching of ores that are not moved from their original natural location. 

Those portions of metal mining facilities at which in situ leaching and associated copper recovery operations occur, including surface applications of acid leaching solutions and deep well injection of acid leaching solutions.

A person receiving groundwater from a municipal provider for non-irrigation uses to which specific conservation requirements apply, including turf-related facilities, large-scale cooling facilities, and publicly-owned rights-of-way.

Water that is used by an industrial user directly in the creation or manufacture of a product.

An industrial use is a non-irrigation use of water not supplied by a city, town or private water company, including animal industry use and expanded animal industry use (A.R.S. § 45-561(5)). 

A person who uses water for industrial uses.
