A Boulder County private well starts with a state permit record

A private well sitting in the yard is not the thing that proves your right to use it. That proof lives at the state level, with the Colorado Division of Water Resources, which handles the permitting, keeps the well records, and runs the searches that let you look one up.

Out in the foothills, the mountain towns, and the rural stretches of the county, plenty of homes are not on city water and lean on a well instead. The pipe and pump you can see are only half the picture. The permit is where the rules live: it tells you what kind of well it is and what uses the water is actually allowed to serve, whether that is a single household, livestock, a garden, or something more.

For a buyer, this is one of the cleaner checks to knock out early. Get the permit number, run it through the state’s well search, and hold the allowed uses up against how you actually plan to live on the land. A well permitted for indoor household use only is a very different proposition from one cleared to water stock and irrigate, and you want to learn that before closing, not after you have planted an orchard.

Boulder County’s private well page is a fine starting point for local owner guidance on water quality and testing. For the permit itself, though, the Division of Water Resources holds the official record, and that is the one that settles what you can and cannot do.
