Water extraction refers to the process of obtaining water from various sources, such as rivers, lakes, aquifers, or even the atmosphere. This water can be used for various purposes, including drinking, irrigation, and industrial processes. Techniques for water extraction vary, including drilling wells, using pumps, or collecting rainwater. The extracted water must often be treated to remove impurities and ensure it is safe for consumption. Water treatment processes can include filtration, chlorination, and reverse osmosis. Proper management of water extraction is essential to maintain sustainable water supplies and protect ecosystems from over-extraction.
