Everything You Need to Know About Permits, Process, and Professional Help

Thinking of drilling a well in Arizona? Whether you’re building your dream home, starting a ranch, or setting up an off-grid retreat, one thing’s for sure—you’ll need water.

This guide is here to walk you through the entire process, step by step, including permits, common pitfalls, timelines, and expert advice straight from the pros at Western Drilling.

Step-by-Step: How to Drill a Well in Arizona

1. Check Your Property Eligibility

Is there enough space? Western Drilling typically needs ½ to ¾ of an acre.
Consider distance from septic systems (at least 100 feet).
Lot size: Over 5 acres simplifies permitting; under 5 acres requires more coordination.

2. Permit Requirements

Arizona Department of Water Resources (ADWR) – the primary agency for well permits.
County Agencies – some counties require additional approvals (e.g., Maricopa County Environmental Division).
You’ll need a “Drill Card” (well drilling permit).

3. Permit Application Process

Estimated timeline: Generally 3-6 weeks, possibly 4-8 depending on the county.
Can be expedited for emergency replacements.
Required documents vary: site plans, environmental assessments, and hydro studies may be needed.

4. Research Nearby Wells (ADWR 5.5 Site)

5. Common Mistakes to Avoid

Drilling too close to a septic system (yours or your neighbor’s).
Contacting the wrong county department.
Skipping research on nearby well data.

6. Special Situations

Agricultural or Commercial Wells: Require hydrogeologic studies and additional forms.
Smaller Lots: May require a referral to a different driller with smaller rigs.
