Water systems refer to the interconnected networks that manage the collection, treatment, and distribution of water for various uses. These systems include sources like rivers, lakes, and aquifers, which supply water, as well as treatment facilities that ensure the water is safe for consumption. In addition to providing drinking water, water systems also handle wastewater management, which involves the collection and treatment of used water before it is released back into the environment. Effective water systems are essential for public health, agriculture, and industry, ensuring that communities have reliable access to clean water and sanitation.
