The word “well” may conjure up images of farmers pulling heavy wooden buckets from a stone hole, but modern water wells have eliminated the need for labor. At the most basic level, a water well is a no-fuss mechanism that collects groundwater and moves it through your home’s plumbing. While you’ll need a professional to actually install the well, you don’t need to be an expert to understand how water wells work.
Well Screen and Casing
At the well’s lowest point is the screen, which naturally filters out sediment and tiny debris. As water rises through the screen, it enters a length of pipe connecting the well system, called the casing.
Well Pump and Head
The water pump is the component that extracts water from the ground and sends it from the casing throughout the home. The pump can be submersible or mounted above ground. The well head consists of the tip of the casing sticking out of the ground, onto which a secure cap is placed to ensure no debris or curious creatures find their way into the well.
Distribution Pipe and Pressure Tank
After the water has been strained through the screen and pumped up the casing, it enters the distribution pipe, which connects the water directly to your home. A pressure tank is then used to force water through the plumbing of your home to ensure adequate water pressure from all faucets and fixtures.
A well is a simple system that typically requires only a quick installation and surprisingly little maintenance thereafter. Different water pump systems may change the well’s speed and efficiency, but all systems provide the same basic benefits. A water well is an investment that gets rid of the costs of city water usage and provides great-tasting, naturally filtered water.
