Whether a new home can legally get its own water here — the sub-state groundwater regime, from Arizona’s water agency.
This basin is under active state management — new water use is scrutinized, though a domestic well is usually still allowed.
Small non-irrigation 'exempt' wells (pump capacity 35 gpm or less) are allowed statewide, including inside Active Management Areas and INAs, but must be registered with ADWR; outside any AMA/INA groundwater is essentially rule of capture. Inside an AMA a new subdivision or large use must show an Assured Water Supply.
Limit: exempt well = pump capacity 35 gpm or less (A.R.S. §45-454)
Arizona Dept of Water Resources — Exempt Well ↗Management goal is planned depletion, not safe-yield; Assured/Adequate Water Supply rules apply to new subdivisions; small domestic exempt wells (≤35 gpm) still allowed but must be registered.
Arizona Dept of Water Resources — AMA Overview ↗New subdivisions and large groundwater uses must demonstrate an Assured Water Supply and obtain ADWR authorization; small domestic exempt wells (≤35 gpm) still allowed but must be registered.
