Sewage is best defined as water that contains human or animal waste along with other elements. This definition encompasses a broader range of materials typically found in sewage, which includes not only the excreta from toilets but also waste from various domestic activities, food preparation, and personal hygiene practices. By including both human and animal waste, the definition captures all potential sources of contamination in water that can lead to health risks and environmental issues.

The broader context of this definition is critical in understanding the complexities of sewage systems and the treatment processes necessary to manage waste effectively. It reflects the combined impact of domestic, industrial, and agricultural activities that all contribute to the sewage system. Recognizing sewage as a mixture allows for appropriate treatment methods to be applied, ensuring public health and environmental protection.
