A well’s casing is the material that lines the sides of the well-shaft, lending support to the structure and protecting the wires, pipes, and other components that allow the well to function. Well companies take several factors into account when choosing the casing, including environmental and geological concerns. Here are a few of the benefits of steel versus plastic casings.

The Differences Between Steel & Plastic Casings

Steel won’t crack during the installation process, which leaves the well in the best and most effective condition possible. For many years, these qualities made well companies choose steel most frequently.


Thermoplastic, also called PVC, has become much more prominent as a material for well casings over the past several decades. This is the result of advances in manufacturing that have made it stronger and more corrosion-resistant. One big advantage to plastic is the fact that it doesn’t break down from high alkaline content in the water. Also, plastic doesn’t conduct electricity, which means it won’t degrade from electrolysis. This contributes to the longevity of the well.

Environmental Factors

In making this choice, your well company will consider how alkaline or acidic the water is, and whether there are any other factors present that might contribute to corrosion. Additionally, some states have requirements for what type of material must be used.
