Water Well Drilling Process

Water Well Drilling Process

Before drilling a well, it’s important to understand the water well drilling process. It begins with obtaining the necessary permits and approvals, followed by the locating and surveying of the drilling site. Once those steps are completed, the well drilling can begin.

Drilling: The process of drilling the well involves using a drill bit that is connected to a drill stem. As the drill bit is turned, it cuts through the soil, rock, and other geological material and loosens it so that it can be removed from the well. The loosened material is then removed by a pump, allowing the drill bit to proceed deeper into the ground.

Casing: Once the desired depth has been reached, the well is lined with casing. This is a steel or plastic pipe that is installed to maintain the structural integrity of the hole and to prevent the walls from collapsing. The casing also prevents contamination of the water supply by keeping contaminants out of the well.

Screen: A screen is then installed at the bottom of the well, which is designed to allow water to enter the well while keeping out sand and other particles. Once the screen is in place, a pump is installed to draw the water from the well.

Testing: After the well has been drilled and cased, it is tested to ensure that it is functioning properly. This includes testing for water clarity, pH, and other factors. It is also important to test for any contaminants that may be present in the water supply.

Capping: The last step in the process is capping the well. This is done to prevent contamination from entering the well and to maintain the structural integrity of the well.

By understanding the water well drilling process, you can ensure that you are taking the necessary steps to find a reliable water supply. Knowing what to look for and what to expect when drilling a well will help you make an informed decision about the best place to find a reliable water supply.
