The majority of a well's design is underground.
Water wells are commonly dug in areas where a home's main source of water comes from the groundwater supply and not city plumbing. Most people associate wells with a column rising above the ground and a long hole. In reality, wells are designed to capture the flow of groundwater. Does this Spark an idea?
Geology
Geology greatly influences the design of a well. According to the Institute of Geologists of Ireland website, groundwater flows downhill with the aid of gravity. Wells must be positioned to properly capture the water without causing it to simply flow around the well.
Pump Equipment
Wells must be wide enough to include pumping equipment that brings the water to the surface of the well. According to the American Ground Water Trust website, common house wells use pumping equipment about 4 inches in diameter.
Depth
The depth of a well is commonly determined on site during the drilling process. Rocks and groundwater flow influence how deep the well is dug. Most wells are lined with steel or plastic casings. The type of casing may be influenced by government regulations.
Well Screens
Screens are used to maximize the flow of water into a well and to keep rocks and debris out of the well. Screens are commonly made from plastic or stainless steel. They are machine-cut with the directions of the cuts being ideal for the way water flows on site.
Well Cap
Well caps fit over the top of well. The caps prevent insects and other things from contaminating well water. Well caps should contain air vents that allow falling water levels to be replaced with air.
