Maybe you recently moved to a rural area on a property that currently has a water well or perhaps you are considering a move to the country and plan to build. Either way, a water well will most likely be a main, if not the only, source of water for your home. As a company that provides well installation for Jordan and surrounding areas, we want to cover some basics of water wells, so you can understand how they work.
Basic Components of a Water Well System
First, it helps to know what makes up a water well system. Here are the basic parts and their functions:
Well Casing – This is inserted into the drilled well to keep the hole open and protect the quality of water in the well. The most common materials for well casing are carbon steel and plastic (mostly PVC).
Wellhead – The portion of the well casing that extends above the surface of the ground, is capped and allows access to the well.
Well Cap – This goes on top of the well casing above the surface of the ground. It fits snugly so debris, insects or small animals can’t find their way into the well system. Well caps are usually aluminum or thermoplastic and have a vented screen to equalize pressure when water is pumped out.
Well Screen – This attaches to the bottom of the casing, allowing water to move through the well while keeping out most excess sediment, sand and gravel.
Pump – Two types of pumps dominate the household well market: jet pumps, which are mounted above the ground, and submersible pumps, which are housed underwater down in the well.
Pitless Adapter – This connector is installed underground below the frost line and provides a sanitary seal between the well casing and the water line running to the house.
Distribution Pipe – This carries water from the well to the house. In colder climates, like Minnesota, this is buried to prevent freezing.
Pressure tank – This is usually located in the house, and they range in size from 20 to 80 gallons. These tanks deliver water under pressure so the pump doesn’t have to operate every time water is used.
Water treatment equipment – Depending on what is being treated and how, this equipment can be located anywhere in the well system or even inside the house to remove contaminates.
How Wells Work
A water well operates much like a person using a straw in a glass of water. The straw is the well and the glass is the aquifer that holds underground water. The person using the straw is like a well pump drawing water out of the aquifer. The person’s digestive system receives the water like a distribution pipe and removes impurities like water treatment equipment so the safe water is available to the body or well owners.
