Water in Coconino County
What the state and federal record says about water across Coconino County. Each figure names the agency it came from.
Can I drill a well here?
Yes, an exempt well of 35 gallons a minute or less
-
Outside an Active Management Area
An exempt well (35 gallons a minute or less) is allowed for any use but irrigation, with no yearly cap. Domestic use includes growing plants on under two acres.
- Every well needs a notice of intention to drill filed with ADWR and a licensed driller. On five acres or less the county health authority also signs off the site plan, and no well may sit within 100 feet of a septic system.

The water here stands a long way below the surface
The water table sits 284 feet down in the typical square mile, against 150 ft in the median county. That is not the depth of the hole, it is where the water stands in it, and it sets the pump, the lift and the power bill for as long as the well runs.

Wells here come in weak
The typical well makes 15 gallons a minute, against 20 gpm in the median county. A household needs roughly 5 to 10, so this is liveable and it will not support irrigation, livestock at scale, or a second home on the same well.

Wells here have to go a long way down
The typical well is 500 feet deep, across 5,784 wells on record. Drilling is priced by the foot and the casing with it, so depth is the first line of any estimate for putting water on raw land, and it is the number a seller is least likely to volunteer.

The water table here recovered and has started falling again
Over twenty years the water table is up 1.9 feet, which reads as a county that came back. The last ten years run the other way at -1.2 feet. Anyone quoting the twenty-year figure is quoting a recovery that has already reversed.
