Determining The Depth Of A Residential Water Well

Construction & Contractors Blog

If you've been considering getting a new well to provide water for your home, the depth of the well can vary depending on a number of different factors. The deeper the well, the higher the cost will be for you. When it comes to understanding how deep your well will need to be, there are several different factors at play. Here is some helpful information so you can understand how well drilling works and what will determine the depth of your particular well.

Measuring Depth

When it comes to deciding how deep your home's well should be, the contractor will take several different factors into account. The geology of your area is the most important, since some regions of the country have a rockier ground or bedrock underneath the soil, which can make it more difficult to drill and harder to reach the ground water. A skilled well contractor uses different tools like a ground scanning machine to determine how deep the well should be, as well as geological knowledge of your local area. For example, in some regions of the country well water can be found in as shallow as one or two hundred feet deep, while in other areas it can be found as deep down as one thousand feet.

Getting To Water

The water for wells is delivered via underground aquifers. These are pockets of water found within the bedrock deep underground. These aquifers can be located at a variety of different depths, so it depends on where they are in relation to your home to determine how deep they will need to drill. Some homes use a bedrock well, which is drilled directly into solid rock. The water flows through the cracks in the bedrock, providing easier access to the water. A special casing is installed into the bedrock to prevent sand and surface water from getting into your water supply. This alternative method of well drilling and installation may not require the contractor to drill as deep, since they will not have to drill all the way to reach the underground aquifer.

Determining Final Depth

Most well drilling companies charge customers by the foot in terms of drilling depth. By combining a property examination, a scan of the ground below, and calculating the average depth to reach water for your particular area, well installation contractors can give you an estimated number of feet down they will need to drill. If they happen to discover an adequate supply of water underground at a more shallow depth, they can cease drilling and you may be able to save some money. However, if the well drilling company does not find a water source and they've already drilled to the depth they originally estimated, they may have to continue deeper until they reach the source. The process to drill the well should take about one full day, and an additional day will be needed to install your well pump.

Stop Mold in Its Tracks

Hi, I'm Carey Johnson. Mold can be more dangerous than you might realize. I learned that when my little girl started having asthma and allergy attacks inside the house. I couldn’t figure out what was causing it. We changed the filter in the air conditioner frequently, and we kept the house very clean. We couldn’t, however, figure out where the allergens were coming from. Finally, we discovered the mold that was growing on the floor of the attic – right above my daughter’s room! No wonder she was having breathing problems! Once we found it, we went right to work learning how to get rid of it for good. We ended up reconstructing the attic, and I learned that I enjoyed learning about construction.
