Close to half of the U.S. population relies on groundwater every day. If you’re preparing to join these ranks, you may wonder what happens during well drilling. To help you know what to expect, here are a few parts of the system your contractor installs.

What Are the Main Parts of a Well ?

1. Cap 

The well cap is your first line of defense against contamination. Part of the casing is above ground, so it’s exposed to outside elements. When properly fitted, the cap prevents dirt, leaves, objects, and pests from entering the casing.

Normally, this component is made of aluminum or thermoplastic. These long-lasting materials withstand inclement weather for several years.

2. Casing

Located beneath the cap, the casing is a tube-shaped structure that supports the well opening. It’s a critical part of the system because it helps protect groundwater from soil contaminants.

Well casing materials vary depending on the composition of the ground, but common options include plastic, stainless steel, and carbon steel. Concrete and fiberglass are also common in some parts of the country. Your well drilling contractor will determine the right material prior to installation. 

3. Screen

Only used in some parts of the country. Homeowners don’t want to see debris in their drinking water, even if they’re harmless. Well screens help keep sediments from entering the supply. They are situated at the bottom of the casing, and allow water to flow through freely while catching dirt and rocks. Bedrock wells do not have screens

Screens are generally made from metal or plastic. They are built with different perforation sizes to capture as many materials as possible.
