Well Registry Number

The Arizona Groundwater Management Act of 1980, mandated that all property owners register their wells with the Arizona Department of Water Resources (“ADWR”). The Act also requires all well owners to maintain accurate ownership information with the ADWR. Frequently well properties are sold or transferred without informing the ADWR that there was a change in ownership. Simply recording a deed of title with the county recorder does not notify the ADWR that the well has changed ownership. As such, many original property owners are still listed with the ADWR as the current owner.

Well Registry Numbers– The Arizona Department of Water Resources (ADWR) assigns a well registry number to each well when it is drilled. The well registry number is a unique number assigned to only one well. They are similar to a car’s Vehicle Identification Number (“VIN”) or a person’s social security number in that each has it’s own unique number.

Well Registry Number’s “55-“. All well registry numbers all begin with “55-” and are then followed by six numerical digits. Well Registry Numbers do not change even if the well changes ownership.

Verifying Well Ownership With the ADWR

Well ownership can be checked by visiting the ADWR’s website. Click HERE. You can search by using the Well Registry Number, Property Owner Name or Search of Location (Township/Range, Parcel, Cadastral, Basin or Sub-basin). If you want help using the ADWR’s website you can watch a YouTube video I made explained the process in detail. Click HERE to watch my video.

Registering a Water Well

If your water well is not registered in your name, you may not have a “known or definable” source of water for your home. Arizona does not consider groundwater to be private property belonging to the landowner. Exempt well water rights are more like an operating permit to withdraw a state managed natural resource.

Additionally, if a well is not registered in the owner’s name the ADWR cannot provide important notices of changes in groundwater laws that may affect their water rights.

ADWR Forms Mandated by A.R.S § Title 45

Form DWR 55-71A can be used to update the ADWR of the new owner. That same form can also be used to correct or change well location information, the name of the well drilling company to be used to drill or deepen the well, or any other pertinent information about the well.

Escrow officers will often use this form to record a transfer of well ownership with the Arizona Department of Water Resources at the time of escrow closing.

Locating Well Records

There are three basic ways to locate Arizona water well records. You can access well file data in the ADWR Imaged Records database the following ways;

1. Using the well registration number (55-000000), 2) by entering the file or cadastral (registry of real state property) designation of your well, or 3) by finding and clicking on a red dot a topographic map of the state of Arizona where your well is located. After locating your well records, you can download them in a pdf file format.

The first step is logging on to the ADWR web site as explained below. Log on to the ADWR Home Page and scroll down to Quick Links: and click on the Imaged Records logo, which will direct you to a page with a box named Search ADWR’s Imaged Records. Change the Imaged Record: field from “Groundwater Document” to “Well Record Document” using the scroll down menu on the right. Additionally, click HERE for a video that shows you step by step how to locate your well’s records with the ADWR.
