Well Drilling Contractors in Arizona

Across the 239,536 Arizona well records in the DrillerDB database, completed wells average roughly 346 feet deep. Actual depth varies widely by location and geology, so a local driller will size your well to the aquifer beneath your property.

A complete private well system in Arizona typically runs $5,000-$20,000, depending on depth, geology, and the pump and treatment you need. Get written estimates from at least two licensed contractors, since per-foot drilling rates and site access drive most of the variation.

Permitting in Arizona: ADWR NOI required (A.R.S. Section 45-595). A licensed water well contractor can confirm the exact requirements for your county and handle the paperwork as part of the job.

From planning to usable water, a Arizona project typically takes 3-8 weeks. The drilling itself is usually only a few days; permitting, water testing, and scheduling account for most of the timeline.

Choose a state-licensed, insured contractor with local Arizona experience. Verify their license, ask for references on recent nearby projects, and get multiple written estimates. The directory above lists verified contractors serving Arizona.
