Do I need a license to drill a water well?
Yes. It is unlawful for any person to construct, alter, or rehabilitate a water well or install pumping equipment in a water well without a license as provided by W.S. 33-42-101 through 33-42-117 unless you are:
Drilling an oil or gas well or installing a pump in an oil or gas well, where the oil and gas well is permitted pursuant to W. S. 30-5-115,
Installing a pump in a well on land owned by or leased to you or on which you are employed on a regular basis,
Drilling a monitoring well that does not require a permit from the State Engineer (i.e., a well with a nominal casing size less than 4-inches in diameter and used exclusively for obtaining water quality samples or water levels),
Drilling on land owned by you, or
Operating drilling equipment or conducting other drilling or boring operations which do not require a permit from the State Engineer to appropriate groundwater (e.g., uranium test holes).
Do I need a permit to drill a water well?
Yes. Any person who intends to acquire the right to beneficial use of any underground water in the state of Wyoming, shall, before commencing construction of any well or other means of obtaining underground water or performing any work in connection with construction or proposed appropriation of underground water or any manner utilizing the water for beneficial purposes, shall file with the State Engineer an application for a permit to make the appropriation (i.e., an Application for Permit to Appropriate Ground Water, or a U.W. 5 Form) and shall not proceed with any construction or work until a permit is granted by the State Engineer (W.S. 41-3-930).
Who has to comply with the Water Well Minimum Construction Standards?
It is the joint responsibility of the drilling and/or pump contractor(s) and well owner(s) to comply with these standards. Further, the well owner(s) must maintain a well in a condition so that it does not contribute to contamination (pollution) of the groundwater supply.
Every well constructed or repaired with a withdrawal of well casing after the adoption of these standards must comply with them. Any deviation from these standards must be approved in writing by the State Engineer or his designee.
What happens if I don’t comply with the Water Well Minimum Construction Standards?
If compliance with these Water Well Minimum Construction Standards will not result in a well that is sufficiently sealed from either surface or subsurface contamination, then the drilling and/or pump contractor(s) and well owner(s) must use additional safeguards to protect the groundwater supply and its users.
The State Engineer is authorized and empowered on advice and consent of the Board of Control to require the abatement of any condition, or the sealing of the well, responsible for the admission of polluting materials into an underground water supply.
What if I want to construct a well differently than that allowed by the Water Well Minimum Construction Standards?
Any waiver or variance to these Water Well Minimum Construction Standards can only be obtained by applying for the waiver or variance to the State Engineer in writing – and before the well is constructed. The waiver or variance will not result in a well that will have a detrimental effect on the groundwater resource.
Must my license be displayed on the job site?
Yes. A copy of the license of a licensed water well drilling licensee or water well pump installation licensee overseeing the job and assuming liability for the water well drilling or water well pump installation shall be conspicuously posted at the water well drilling or water well pump installation site.
