Well Driller List

State rules

Arizona

Arizona requires a licensed well-drilling contractor to drill a new well or to deepen or modify an existing well. The Arizona Department of Water Resources explains that a Notice of Intent to Drill is filed before that work, with the filing fee the form requires. Authority to drill a new well or deepen an existing well is valid for one year, and a new notice is required after that. ADWR also licenses the drillers who do the work and gives licensing exams on the second Friday of each month. Licenses are renewed annually. A public drillers list can be searched by company, zip code, or qualifying party. This record does not copy names from that list.

ADWR's well-drilling page says the department regulates groundwater wells and that construction standards are meant to keep contaminants out of the well and the surrounding groundwater. Exempt wells are described as wells equipped to pump 35 gallons per minute or less, often for household uses. Non-exempt wells pump more than that, and in active management areas they need a groundwater right or permit such as a grandfathered right, a service-area right, or a withdrawal permit. Shared-well agreements are private contracts. ADWR says it does not regulate those agreements and does not give legal advice about them.

Arizona Revised Statutes section 45-595 says new well construction, including modifications, shall be performed under the direct and personal supervision of a well driller who holds a well driller's license. A person who intends to construct or modify wells files an application with the director. The statute directs the director to set qualifications and a fee of not more than fifty dollars, and it says the license is nontransferable. A person drilling an exempt well on that person's own land must first obtain a single-well license, and the statute says no fee may be charged for that single-well license.

The department's contact block for well questions lists 1110 West Washington Street, Suite 310, Phoenix, and the phone number (602) 771-8527. Licensing exams are given at ADWR on the second Friday of every month, and the page says to call that number about becoming licensed or renewing. Drillers can file certain notices online and can file drill logs electronically. Abandonment is described as filling or sealing the well, including the annular space, so it is not a vertical channel for water. Spacing rules apply to some new wells and uses, and the page lists categories those rules do not cover.

What to do next

  1. Search the ADWR drillers list instead of relying on a copied roster.
  2. Ask for the drill card and the approved location before work starts.
  3. Ask whether the well will be exempt or will need a groundwater right.
  4. Ask how an unused borehole or finished well would be abandoned under ADWR rules.
