How a Colorado well permit actually gets issued
Colorado wells are state paperwork, start to finish — the Division of Water Resources issues the permit, licenses the drillers, and keeps the records (checked July 2026). Here’s the process without the folklore.
First question: exempt or not?
Everything branches on capacity. Exempt wells — household-use and domestic/livestock wells — sit outside the prior-appropriation priority system; that’s the ordinary rural home well, and its paperwork is straightforward. Non-exempt wells — irrigation, commercial, higher-capacity — enter the water-rights world, where augmentation plans and the priority line live. If your project is a house on acreage, you’re almost certainly on the exempt path; if it’s anything bigger, budget for engineering help before the form.
The six steps
- Match your situation to a form — new exempt well, replacement, registration of an old unpermitted well, change of ownership.
- Complete the application — property map, proposed well location, and the use you’re claiming.
- Line up a licensed driller — construction details come from a licensed contractor, and DWR’s driller licensing is part of the same system.
- File with the fee — each form carries its own fee on DWR’s schedule; typical exempt filings run about $100 (see our cost breakdown).
- DWR review — the state checks the application against existing rights and the rules for your basin.
- Drill and report — after construction, the well construction and yield report goes back to DWR, and the permit’s conditions become the well’s permanent record.
The two clocks worth respecting
The permit’s expiration — construct before it lapses, or file the free extension before the date, not after. And the closing calendar — at a sale, the permit record, the ownership transfer, and the lender’s testing requirements all converge on the same few weeks. The sellers who sail through are the ones whose paperwork matched the property before the buyer’s lender started asking.
Questions people actually ask
What's the difference between exempt and non-exempt wells?
Exempt wells are the small-capacity household and domestic/stock wells that operate outside Colorado's prior-appropriation priority system — the typical rural home well. Non-exempt wells are the larger-capacity irrigation, commercial, and supply wells that stand in the water-rights priority line. Nearly everything about your paperwork flows from which side you're on.
Who issues well permits in Colorado?
The Division of Water Resources (DWR, the State Engineer's office) — not your county. Counties handle septic and building permits; the well itself is state paperwork, filed with DWR with the fee for your specific form.
Do well permits expire?
A new permit carries an expiration date, and the well must be constructed and reported before it. If the driller can't get there in time, extending an exempt or small-capacity permit's expiration is free — a form, not a fee. An expired permit before construction means starting over.
What happens to the permit when a property sells?
The permit stays with the well, but the ownership record should follow the property — a change-of-ownership filing with DWR. It's routinely missed, then surfaces during a later sale or when a replacement permit is needed. Our transfer guide covers the form and the closing-table timing.
