Wastewater refers to liquid waste from households, hospitals, industries, and other sources that is carried away through sewers. It contains organic and inorganic impurities as well as disease-causing bacteria. Wastewater treatment involves screening, primary treatment to remove solids, secondary treatment using bacteria, and final treatment including filtration to make the water usable again before releasing it. Proper sanitation and sewage systems are needed to safely collect and dispose of human waste.
