An intake well is a structure that is typically built near a water source, such as a river or lake, to collect water for various purposes. It is usually a vertical cylindrical shaft constructed of concrete or masonry, with a screen or a grate at the bottom to prevent debris and sediment from entering the well.The water collected in an intake well is often used for drinking water, irrigation, or industrial processes. The well is designed to draw in water through the screen or grate and then transfer it to a treatment facility or a distribution system through pipes or channels.
