Copyright © 2016 KCW Water Well Service

Modern water well systems are somewhat complicated. If you feel the need to install water well in your home, you’ve got to do a little bit of research and understand the types of wells in the market before you invest in the project.

We’ll cover the basic types of water wells and advice you on how to choose the best one. Just remember, each type of water well is suitable for a unique set of needs. You need to understand your needs first before you choose the best water well system for your property.

Drilled wells

As the name suggests, this type of well is constructed using modern drilling machines. Because the wells are designed to penetrate unconsolidated material, they can have a depth of more than a thousand feet. They are also constructed with a casing so that the system doesn’t collapse. Different types of drilled wells utilize different forms of sealing to reduce the risk of contamination and also ensure that the well finish is neat. In most cases, cement or clay is used to seal the interior of the well. This type of well needs to be properly constructed; it reduces any risks of contamination.

Driven point wells

These are much smaller wells that are usually less than 50 feet deep. They are constructed using pipes and are suitable for areas that have loose soil. Also known as sand point wells, they are mostly preferred because they are cost effective as well as simple to install.

The main disadvantage is that driven point wells can only be used to tap shallow water which means that the risk of contamination is quite high compared to drilled wells. These wells often do not have any kind of sealing which further increases the risk of contamination. They can be built by hand or using machines.

Dug wells

This type of well is often built by hand. The well is quite shallow and has a large diameter hole. Because most dug wells tap shallow water, they pose the highest risk of contamination. Dug wells are not the best solution for tapping drinking water.

This type of well is not properly protected from the water surface and this is what poses a great health risk. Dug wells can be lined using stones, tiles or bricks and are often covered using a cap made of wood. This type of well can get its water from fine sand or clay. The other major risk when it comes to dug wells is that they can go dry when there’s drought because of a drop in the water table.

How to choose the best one

When choosing the right type of well, you’ll need to consider factors such as the cost of installation, the location as well as weather conditions in your area. A dug well may not be ideal in environments which are prone to drought because it goes dry easily. The cost of drilled wells may also be too high for some properties and other options like sand point wells can be considered.
