subterranean water reservoir

A subterranean water reservoir, also known as an aquifer, is an underground layer of permeable rock, gravel, or sand that stores and transmits groundwater. Think of it as a hidden, natural underground reservoir where rain and surface water seep down through soil and rock, accumulating in porous spaces. These reservoirs supply water for wells, springs, and various uses like agriculture and drinking water. They are vital environmental resources, naturally replenished by rainfall, but can be depleted if overused or contaminated. Proper management ensures sustainable access to this essential underground water source.
