An Adams County private well starts with a state permit

A private well in Adams County answers to the State of Colorado, not the county courthouse. Groundwater here is a state-managed resource, and the Colorado Division of Water Resources is the office that issues well permits and keeps the records. Every legal well traces back to one of those permits, with allowed uses and conditions written into it.

The county is not absent, though. Adams County’s development standards fold in water-supply questions for individual wells and for special district service plans, including an analysis of the impacts caused by pumping from the aquifer. So a well can clear the state permit and still face county review when it is tied to building or subdividing.

This shows its teeth on eastern-plains parcels, farms, rural homesteads, and raw development sites, where a property may already have a well house, a pump, and maybe an old hand-written note about it. None of that equals an official permit. The hardware tells you water was pumped once; only the permit tells you what uses are allowed and under what limits.

The careful sequence is to search the Division of Water Resources records and read the permit before you count on the well at all. Then check whether the county wants proof of water availability for your building, land-use, or subdivision path. And if you plan to use the water in a way the old permit never covered, settle that question first, rather than designing a project around an assumption the record will not support.
