Water rights & wells in Summit County

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

Closed to new supply

New water supply here generally requires a permit, an offset, or buying an existing right — a household well is not automatic.

Household wellPermit required — restricted

Utah has NO exempt domestic well — you must own a water right to drill any well, including a household well. In an open area you file a new appropriation, but because much of Utah is closed to new appropriation a newcomer typically must PURCHASE an existing water right and file a change application to move it to the new well.

Limit: ~0.45 acre-ft/yr indoor domestic (typical allocation); no statutory exempt-well quantity
