A water well is a structure created to access groundwater, which is water located beneath the Earth's surface. Wells are typically drilled or dug into the ground until they reach an aquifer, a layer of water-bearing rock or sediment. Once the well is established, water can be pumped to the surface for various uses, including drinking, irrigation, and industrial processes. Water wells can vary in depth and construction methods, depending on the local geology and water needs. They are essential for providing a reliable water supply in areas where surface water is scarce. Proper maintenance and management of water wells are crucial to ensure safe and sustainable water access.
