Wells And Aquifers Working Principle


It is undoubtedly unintuitive that water flows in the soil and rock below our feet. This video covers the basics of groundwater engineering, including how wells are built, how injection wells work, and how aquifers interact with surface water features.

Errata: Deep well jet pumps exist that can lift water greater than 100′ using an ejector and two pipes.An aquifer is an underground layer of water-bearing permeable rock, rock fractures or unconsolidated materials (gravel, sand, or silt). Groundwater from aquifers can be extracted using a water well.

Aquifers vary greatly in their characteristics. The study of water flow in aquifers and the characterization of aquifers is called hydrogeology.


Related terms include aquitard, which is a bed of low permeability along an aquifer,and aquiclude (or aquifuge), which is a solid, impermeable area underlying or overlying an aquifer, the pressure of which could create a confined aquifer./wikipedia
