Well systems are structures designed to extract water or other fluids from underground sources. They typically consist of a borehole, a pump, and a delivery system that transports the fluid to the surface. These systems are essential for providing water for drinking, irrigation, and industrial use, especially in areas where surface water is scarce. The main components of a well system include the well casing, which protects the borehole, and the submersible pump, which lifts the water. Proper maintenance of well systems is crucial to ensure water quality and efficiency, preventing issues like contamination or mechanical failure.
