What are the different methods of harvesting ground water?

Groundwater harvesting is the practice of collecting and storing water on or beneath the surface of the ground for use in times when water availability is limited. In North Carolina, there are several different ways to harvest ground water. One way of ground water harvesting is surface water harvesting. This is the collection and storage of rainwater that falls onto surfaces like rooftops and parking lots. This water is then stored in large tanks and can be used at a later time. Another way of harvesting ground water is aquifer recharge. This is the process of replenishing an aquifer or underground rock formation with water that has percolated, or filtered, down from the surface. Aquifer recharge can be accomplished by the intentional injection of excess surface water into a well or through the installation of infiltration galleries, like trenches that are filled with gravel or porous materials that allow water to enter an aquifer. A third method of ground water harvesting is pond storage. This is the process of storing excess surface water in ponds and other large bodies of water. This water can then be used for irrigation, livestock watering, and other uses. Lastly, the fourth method of ground water harvesting is desalination. This is the process of extracting the salt from saltwater and turning it into freshwater. Desalination is a costly process, but it is a reliable source of water in areas with limited options. Overall, surface water harvesting, aquifer recharge, pond storage, and desalination are the four methods of ground water harvesting available in North Carolina. Each method has its advantages and disadvantages, and all should be taken into consideration when deciding which is the best option.
