Water wells are an important source of water for drinking, irrigation, and industrial use. In many areas of the world, they are the only source of freshwater. Wells provide water for approximately one billion people worldwide.
A water well is basically a hole in the ground that taps into an underground water source. The well water is drawn by an electric submersible pump, a pitcher pump, a jet pump, or gravity flow to surface storage tanks or cisterns. This water is then treated before it is pumped to the home. Some well water requires no treatment and can be used immediately for drinking, cooking, and irrigation.
Most water wells are drilled using a rotary drill rig. The hole is Carson by augering or drilling with large diameter bits. The hole is then cased with steel pipe or PVC plastic pipe and the well screen is installed to keep out sand and gravel. The well screen consists of a perforated pipe wrapped with stainless steel wire mesh. The well screen allows water to enter the hole but keeps out most of the sand and gravel.
The well casing is then locked into place with grout. The space between the outside of the well casing and the hole is filled with grout to prevent the collapse of the hole and to keep out surface water and contaminants. The well is then completed by installing a sanitary seal, such as a rubber gasket, above the groundwater level to keep out surface water and contaminants.
A pump is then installed to bring the water to the surface. The pump may be installed inside the well or outside the well, depending on the depth of the well and the construction of the well.
If the well is less than 50 feet deep, the pump may be installed inside the well. If the well is more than 50 feet deep, the pump may be installed outside the well. The type of pump used depends on the depth of the well and the amount of water that is needed.
Submersible pumps are used for wells that are less than 400 feet deep. The pump is placed inside the well and is submerged in the water. The submersible pump is powered by an electric motor.
Jet pumps are used for wells that are less than 25 feet deep. The jet pump uses a high-pressure stream of water to push the water up the well. The jet pump is powered by an electric motor.
Pitcher pumps are used for wells that are less than 25 feet deep. The pitcher pump uses a handle to lift the water up the well. The pitcher pump is powered by human power.
Gravity flow systems are used for wells that are more than 400 feet deep. The gravity flow system uses the force of gravity to pull the water up the well.
The water from the well is then treated before it is used. The type of treatment depends on the type of water in the well.
Water from some wells contains minerals that can be harmful to your health. Water from these wells must be treated to remove the minerals. Treatment methods include reverse osmosis, distillation, and deionization.
This is how well does get water. The process is quite simple, a hole is dug or drilled until water is reached. A pump is then used to bring the water to the surface. The water is then treated before it is used.
