Sewage refers to waste water and materials that are produced from homes, businesses, and industries, including human waste, food scraps, and other waste products. It is carried away through pipes to be treated at sewage treatment plants, where harmful substances are removed before the water is released back into the environment or reused. Sewage can include water from toilets, sinks, showers, and drains, and its proper treatment and disposal are important for public health and preventing pollution. When not managed correctly, sewage can cause contamination and health risks.
