Administrative Rules for Water Well Drillers
(R655-4 Utah Administrative Code)
“Provide order and certainty in the beneficial use
of Utah’s water”

WELL DRILLING DEFINITION
Well drilling means the act of drilling, constructing, repairing, renovating, deepening, cleaning, developing, or abandoning a well Incidental or appurtenant work around the well is not regulated by the Rules

OPEN LOOP SYSTEMSGroundwater is removed from aquifer via well, circulated through heat exchange system, then re-injected back into aquifer
Re-injection into production well, separate injection well, or to a surface diversion
A non-consumptive use water right is required if re- injecting into same aquifer (aquifer protection and non- degradation standards apply)A consumptive use water right is needed if discharging to surfaceWells must be drilled by a licensed driller and water well construction standards apply

CLOSED LOOP SYSTEMSGroundwater is not removed, nor does the system fluid come into contact with groundwater (sealed and closed system)A closed loop of poly pipe (standard) or copper tubing (direct exchange or DX) is installed into boring and grouted/sealed bottom to top, then an antifreeze/water solution or refrigerant is circulated through the loopsA Non-Production Well Permit is requiredMust be drilled and constructed by a licensed driller and non-production well construction standards apply

Holes in the Regulations?
Systems installed less than 30 feet deepNo control over incidental or appurtenant activity beyond the wellAccidental or intentional non-compliance by drillerClosed loop system abandonment
