This particular type of screen is a filter that allows water to flow and keeps debris and other materials out. In most cases, these specific types of filters are used to keep out gravel/shale and sand out of the well-structure while allowing the maximum amount of water to flow in. It is important to know that ground water is found in the tiny spaces in between the particles of sandstone, rock, gravel beds and even sand.
Sand and gravel are often referred to as unconsolidated aquifers while sandstones and rocks are known as consolidated aquifers. As a result, well screens help prevent rock particles from entering the well that may cause early malfunction of the well-pump or perhaps the plugging equipment. Additionally, the accumulation of sand in the well may lead to blocking off water bearing areas. You can learn more by visiting http://www.cp-screens.com/water-well-screens
How do water wells work?
For most wells, it is preferable to have water enter the well slowly. A turbulent of flow of water can lead to the passing of agitated water and particles that may clog up the wall. For this reason, selecting the appropriate well screen can help improve your well`s efficiency and its productive timeline. One common example of water well-screens is known as the continuous slot constructions that are developed by adorning and welding long strands of wire or PVC around vertical rods.
Well-screens can also be used through accurate machine slotting or by developing shutter or louver openings. Shutter screens are used for wells that have a high yield. The filters are available in many slot openings and apertures that are installed by fixing the screen on one end of the casing that is then lowered down into the well to the water producing zones. In most cases, your local contractor creates a well-screen to accommodate your unique well necessities.
