Being a Master Level Geothermal Contractor
Presented on Tuesday, December 15, 2015
Some water well drilling contractors can be seriously considering diversifying into geothermal operations and some geothermal drilling contractors wish to enhance their skills and efficiency with such installations to improve profitability. This three-hour workshop will address these specific topic areas to enable both groups to do just that:
•Conducting, applying, and having confidence in a thermal conductivity test
•System monitoring and calculations for efficiency
•Grouting applications and selection for best performance and groundwater protection.
Attendees who wish to receive credit for the entire class will be expected to sign in and out. Information on eligibility and sitting for the NGWA Voluntary Certification designation CVCLD (Certified Vertical Closed Loop Driller) will be available to participants.
