Different Types of Water Bore Drillers

A person has to hold a valid water bore drillers license to perform water bore drilling activities in private aquifers. An individual needs to hold a valid bore drilling license to conduct drilling operations inside artesian or sub-artesian aquifer systems in Colorado, Wyoming, Idaho, Nebraska and elsewhere. A license allows an individual to perform water borehole excavation and drilling of any depth. A license also defines the requirement for obtaining special identification / certification and approval to conduct a specific business activity in the state. This is because different licenses are required for different activities. Below are some of the most common types of borehole licenses that are required in the United States:

Water borehole drilling permits are given to individuals who wish to conduct excavation activities in groundwater systems, as well as surface water systems. The main purposes of these licenses are to ensure that water quality and quantity are maintained in the vicinity of the boreholes. The borehole must be located in a natural, porous formation or sedimentary rock unit, such as granite or marble. There should be an open and clear access route from the surface to the ground level for the groundwater to drain into. This allows for proper water delivery for use by plants and animals. The license can be obtained either from the Colorado Department of Natural Resources (DNR), or the Wyoming Department of Environmental Quality (DER).

Other licenses require a permit to conduct drilling operations in the “surface drainage” area in a borehole. In this case, the borehole is drilled in the subsurface but is not actually connected to a groundwater system. This can be achieved in two ways. First, a permit may be obtained from DNR for an individual to drill an exploratory borehole in the subsurface. This permits the individual to locate the location of the borehole, establish the depth of water reaching the surface, and establish the location of a connection point to the groundwater system. Second, a permit may be obtained from DER to excavate an exploratory borehole in the subsurface, but is not connected to a groundwater system. This permits the individual to use the surface for excavation work while conducting their underground drilling.
