Water Well Drilling Contractors in Colorado

Geology & Depth

Colorado's Front Range sits atop the Denver Basin aquifer system with interbedded sandstone and shale layers. The Eastern Plains overlie the Ogallala Formation's sand and gravel, while the Western Slope taps fractured crystalline rock and sedimentary formations.

Most residential wells in Colorado are drilled to 250 feet, with a typical range of 50–700 feet. Water table depth: 50-400 feet along the Front Range; 100-500 feet on the Eastern Plains; highly variable in mountain regions.

Permits & Licensing

Colorado requires all water well contractors to be licensed by the State Board of Examiners of Water Well Construction and Pump Installation Contractors. No homeowner exemption exists.

Permit authority: Colorado Division of Water Resources (State Engineer's Office); every well requires a permit before drilling. Expect $200-$600 in permit fees.

Primary Aquifer

Denver Basin Aquifer System / Ogallala (High Plains) Aquifer. Approximately 18% of Colorado households rely on domestic wells, primarily in unincorporated areas along the Front Range and in mountain communities.

Best drilling months: April through October in most areas; mountain locations limited to June through September.

Common Water Quality Concerns

Colorado well water commonly contains: uranium, radon, arsenic, iron, manganese, selenium. A comprehensive water test after drilling (typically $150–$500) will identify which treatments, if any, your well needs.
