CO Well Driller study guide
CO Well Driller · Work through your exam, one topic at a time.
The Colorado well driller credential covered on this page is the state's water well construction contractor licensing pathway, administered in Colorado by the Division of Water Resources together with the Board of Examiners of Water Well and Ground Heat Exchanger. The Board's rulemaking covers licensing administration, financial responsibility, continuing education, and remedial action for well construction, ground heat exchanger, and pump installation contractors, so the credential is aimed at contractors and operators who build water wells, install ground heat exchanger systems, and install pumps in Colorado. The CO Well Driller study guide has 5 sections and about 2,234 words.
01Well Construction
Well Construction is the core technical domain of the Colorado well driller exam. It tests whether you can take a permitted well from site selection through casing, grouting, development, completion, reporting, and-when necessary-abandonment without creating a pathway for contamination or a cross-connection between aquifers.
446 words, about 2 min02Ground Heat Exchanger Construction
Ground Heat Exchanger Construction covers vertical and other closed-loop boreholes used for geothermal heating and cooling. On the Colorado exam, expect questions on how a GHX borehole is both a construction project and a regulated well: permit and licensing, borehole sealing, loop integrity, separation distances, reporting, and abandonment.
458 words, about 2 min03Pump Installation
Pump Installation tests the licensed contractor’s ability to install, test, and report a pump system that matches the well’s yield and the owner’s demand without damaging the well or contaminating the water. Expect questions on licensing, pump setting, sanitary seals, electrical and pressure controls, testing, and the pump installation report.

This domain tests the business and regulatory side of Colorado well work: who may hold a license, how licenses are renewed and displayed, what financial assurance is required, and what conduct can lead to discipline. It rewards candidates who know the difference between a license, a permit, a bond, and insurance.
436 words, about 2 min05Continuing Education and Remedial Action
This domain covers what happens after licensure: maintaining competency through continuing education and correcting defective work through remedial action or enforcement. Exam questions often turn on deadlines, documentation, and the difference between a routine correction and a formal order.
