Sewage - GCSE Biology Definition

Reviewed by: Lára Marie McIvor

Published

Sewage is a mixture of water and waste materials that comes from homes, businesses, and industry. It contains substances such as human waste, food particles, detergents, and water from toilets, sinks, and showers. Sewage is transported through a network of pipes to treatment plants, where it is processed to remove harmful substances before being safely released into the environment or reused. Studying sewage in GCSE Biology helps explain how human waste is managed and why proper treatment is essential for protecting human health and ecosystems.
