Drilled Well vs. Driven Well: Which Is Right for Utah Properties?
A drilled well uses a powered rotary rig to bore hundreds or thousands of feet through soil and rock; a driven well hammers a small-diameter pipe with a screen point into shallow saturated sediment. In almost every part of Utah, only a drilled well will reach reliable, year-round groundwater — but driven wells still have a few narrow use cases.

How to Decide
- Pick Drilled Well: You want a permanent, year-round water supply for a home, farm, or business — anywhere in Utah.
- Pick Drilled Well: Your property sits on rock or thin alluvium, which describes most of Utah.
- Pick Drilled Well: You need more than 5 GPM, or you need water that will hold up through drought.
- Pick Driven Well: You have a shallow, sandy water table within 25 feet, and you only need a small seasonal supply for a garden, livestock trough, or recreational cabin.
Frequently Asked Questions
Can I drive a sand-point well in Cedar City or St. George?
Almost never. The water table in most of southern Utah is too deep and the formations are too rocky for a driven well to work. Drilled wells are the only practical option.
Are driven wells legal in Utah?
Yes, but they still require an approved water right and a Start Card from the Utah Division of Water Rights, just like a drilled well.
Is a driven well cheaper long-term?
Almost never. The lower install cost is wiped out by short service life, vulnerability to drought, and high contamination risk.
