    Bernalillo County Public Works - Wastewater Permitting Process

Water rights & wells in Bernalillo County

Whether a new home can legally get its own water here — the sub-state groundwater regime, from New Mexico’s water agency.

Over-appropriated / declining

The aquifer here is over-appropriated and declining. A domestic well is usually still permit-exempt, but long-term supply is a genuine risk.

Household wellPermit required (issued by right)

Nearly all developed New Mexico lies inside an OSE 'declared' underground water basin, but a household 72-12-1.1 domestic well is a by-right permit the State Engineer issues even in closed/over-appropriated basins (metering can be required). The by-right amount is cut to 0.25 acre-ft/yr in a declared Domestic Well Management Area, and a few basin-specific orders cap it further (Gallup Order 197, Zuni Order 199) or stop issuing new domestic permits entirely (Hot Springs Order 198).

Limit: 1 acre-ft/yr by right (NMSA 72-12-1.1); 0.25 acre-ft/yr in a declared Domestic Well Management Area

NM OSE domestic well rules, 19.27.5 NMAC
  • Estancia Basinpartial of county

    Valley-fill declines up to ~5 ft/yr with multiple Critical Management Areas; new non-domestic appropriations are rejected and rights cannot be moved into a CMA. A 72-12-1.1 household domestic well is still issued under the statewide rules and basin drawdown limits.

    NM OSE Estancia Basin Guidelines (2021)
  • Middle Rio Grande Basinpartial of county

    Effectively fully appropriated; OSE requires new depletions to be offset by retiring/transferring existing rights. A new home cannot get a fresh non-domestic right without an offset, but a 72-12-1.1 household domestic well remains available by right (metered).

    NM OSE Water Rights District 1

Prior-appropriation state (first in time, first in right). Groundwater rules change and basin boundaries follow the aquifer, not the county line — confirm current well and appropriation rules with the New Mexico state water agency before you buy or drill.Groundwater governance as of Jul 2026, cited to each administering agency.
