A well site evaluation is the groundwork before any drilling starts. It looks at property access, expected geology, groundwater conditions, setback distances from septic systems and property lines, and whether a water right is in place or needs to be filed. Getting this right up front avoids drilling in the wrong spot or hitting an avoidable delay later.
What Does a Site Evaluation Actually Involve?
A site evaluation starts with walking the property to look at topography, access for a drill rig, and distance from existing structures, septic systems, and property lines — Utah has minimum setback rules that affect where a well can legally go. We also check for any drilling records from nearby wells, since those give a rough sense of depth and rock conditions in the area before a bit ever touches the ground. This is a standard part of our well drilling services across Cedar City and the surrounding region.
What Factors Determine Where to Drill?
Several things narrow down the best spot on a property:
- Setback requirements — distance from septic tanks, drain fields, property lines, and any existing wells
- Access — whether a drill rig and support truck can physically reach the location
- Known groundwater conditions — depth and yield patterns from nearby wells, where records exist
- Slope and drainage — a wellhead needs to sit above grade so surface runoff doesn't pool around it
- Future use of the land — leaving room for a driveway, addition, or outbuilding that hasn't been built yet
No two properties in Iron, Washington, or Beaver County line up the same way, which is why this step happens on-site rather than off a map.
How Does Evaluation Differ Between Residential, Commercial, and Agricultural Wells?
The basic process is similar, but what we're solving for changes with intended use.
| Use case | Main site evaluation focus |
|---|---|
| Residential | Setbacks from septic/property lines, access for a smaller rig, proximity to the home |
| Commercial | Anticipated demand (multiple fixtures, irrigation, or equipment), access for larger equipment, utility coordination |
| Agricultural | Field layout, distance to irrigation infrastructure, and matching output to the water right on file |
Agricultural sites, including those evaluated for irrigation well drilling, also factor in how the well ties into existing pivots, ditches, or pressurized irrigation lines already on the property.
What Role Do Water Rights Play in Site Selection?
A site evaluation isn't just about geology — it also has to line up with what's on the water right, since Utah's Division of Water Rights ties a point of diversion to a specific location, not just a property. If the physical best spot to drill doesn't match where the water right allows a well, that has to get sorted out before drilling, not after. We coordinate this step as part of the evaluation rather than treating it as a separate task.
How Long Does a Site Evaluation Take?
Most single-property evaluations for a residential or small commercial well take a single site visit, with a recommendation following shortly after. Agricultural sites with multiple potential well locations or existing irrigation infrastructure to work around can take a bit longer to walk through properly. Either way, this happens before scheduling the drill rig — not as an afterthought once equipment is already on site.
Why This Step Matters
Skipping or rushing a site evaluation is how properties end up with a well in an awkward spot, a setback violation, or a mismatch between the drilled location and the water right on file. A short evaluation up front is far less disruptive than relocating a wellhead or refiling paperwork after the fact.
If you're planning a well anywhere in Iron, Washington, Beaver, Kane, Garfield, Piute, or Wayne County, including near St. George or Richfield, a site evaluation is the right first call before anything else gets scheduled.
