Whether a new home can legally get its own water here — the sub-state groundwater regime, from Wyoming’s water agency.
Groundwater is actively managed here, but a small household well is generally still available.
Unlike most exempt-well states, Wyoming requires a permit for every well including domestic and stock, but the permit for a small domestic/stock well is a simple, routinely granted filing and those uses carry a preferred right (W.S. 41-3-907).
Limit: All wells require a State Engineer's Office permit before drilling; small domestic/stock wells (≤25 gpm) are a routine registration and hold statutory preferred rights
