Water supply companies are organizations responsible for providing clean and safe drinking water to homes and businesses. They source water from various places, such as rivers, lakes, or underground aquifers, and treat it to remove impurities. These companies ensure that the water meets health and safety standards before distributing it through a network of pipes. In addition to supplying water, these companies also manage wastewater treatment, which involves cleaning used water before returning it to the environment. They play a crucial role in maintaining public health and supporting community needs, often working in partnership with local governments and regulatory agencies like the Environmental Protection Agency.
