A low temperature geothermal project (bottom hole temperature less than 250°F and well less than 2,000 feet deep) requires an industrial/commercial water right permit if the project will draw more than 5,000 gallons per day and a low-temperature geothermal well registration with the department.
Please review Division 230 rules “Standards and Procedures Low-Temperature Geothermal Production and Injection Wells and Effluent. We recommend you discuss your proposed project with the Department’s low-temperature geothermal program lead prior to preparing and submitting application forms.
High temperature geothermal projects (bottom hole temperature greater than 250°F or geothermal wells greater than 2,000 feet deep) are permitted through the Department of Geology and Mineral Industries.
