Considerations For The Best Water Well Drilling Method

If you currently use well water and your well is drying up, then you may require the addition of a new well on your property. Wells need to be drilled properly to ensure good function and to minimize the risks of the well collapsing or filling in. A drilling professional can plan and complete the necessary steps to install your new well. Drilling methods will vary, and there are several aspects of your property that will be taken into consideration before the method is chosen.

The Ground Makeup

The makeup of the soil on your property will often determine the best method for drilling. This means that soil samples will be taken at different levels in the earth. If sandy soil is noted, then an auger drilling process will be utilized. The process involves the use of a screw-type drill bit that creates the hole in the soil and then reverses to release the debris from the opening. This helps to clear out the soft soil, so it does not fill in the hole as soon as it is drilled. To best reduce collapsing risks, a casing or pipe is often inserted into the well too.

If the soil content is rocky, then a rotary drilling method will likely be chosen. The drilling involves the use of a drill pipe and a large bit attached to the end of the pipe. This bit can vary in size, shape, and function depending on the type and number of rocks present in the soil. Typically, the bit will have three or more large, pronged moving pieces that rotate when they come into contact with rock. 

Cable tool drilling is another drilling method that is used when combination soils are noted. This method uses a drill bit much like the rotary method, but the bit is attached to a string. The bit is dropped into the well opening to break away debris. The dirt is then moved up towards the surface with bails.

The Depth Of The Well

In certain areas, like ones where the elevation is low in relation to the water level, wells can be fairly shallow. This is also the case in places near lakes and natural aquifers. If you live in a location where water is probably close to the earth's surface, then a had driven drilling method may be appropriate. This type of drilling involves the use of a weighted driver -- a large tool often placed on the back of a commercial vehicle. 

The hand driven drill is used to bore a hole to create the well with or without the use of a casing. The drill is forced into the ground multiple times, while the drilling professional checks for water periodically.
