What is a well? Back in the day, wells were dug by hand using a shovel until the water table was reached. The water would then fill the bottom of the hole to be scooped out and used for various purposes. Although some wells are still dug manually, most of today’s wells are made using heavy duty drilling equipment.
Water wells are important to people all over the world. They can be installed in places that need a reliable water source whether for residential, commercial or agricultural use. On another note, efficient water wells are critical where surface water is scarce—like in the desert or other areas with consistently dry climates. Surviving in such areas is difficult without access to a steady supply of groundwater.
Current and prospective well owners should have a general idea of the different materials and construction methods used. Here are the three most common types of water well systems in Scottsbluff, NE.
If you are not hooked into a public water system, then your water likely comes from a private well on your own land. In the United States, a drilled well is the most common type of water supply for residential homes. A well drilling company will either use percussion or rotary-drilling machines and equipment in order to reach 100 to 400 feet down into the bedrock, though wells can be drilled more than 1,000 feet deep. However, to be considered a suitable water supply, a drilled well must intersect bedrock fractures that contain groundwater. A pump is placed deep down in the well to push groundwater up to the surface.
Dug wells are created using a pick, shovel or other manual digging tools. As one of the oldest water supply technologies available, it’s a much different method than relying on industrial drilling machines, but if the ground was soft enough and the water table shallow, dug wells worked. Once water began coming up from the dug ground, the well was lined with stones, tile, brick or other materials to keep it from collapsing, then covered with a cap made of stone, wood or concrete.
Dug wells are still used today, even though many are at risk of contamination and tend to go dry during droughts. Casing a dug well in a watertight material and using a cement or clay sealant on the outside minimizes the risk of contamination.
Another common well system today is a driven well. To build one, a small-diameter pipe is driven into soft earth like sand or gravel. The bottom of the pipe typically has a screen attached to filter out sand and other tiny particles. The thing about driven wells is that they can only tap shallow water, so it’s not unusual for water contamination from surface contaminants to occur.
