Water sources are natural or artificial locations where water is found. Common natural sources include rivers, lakes, and aquifers, which store groundwater. These sources provide fresh water for drinking, agriculture, and industry. Artificial sources, such as reservoirs and water treatment plants, are created to manage and supply water to communities. Rainwater harvesting is another method that collects rain for use. Understanding these sources is essential for sustainable water management and ensuring access to clean water for all.
