What is the main type of wastewater treated in facilities for both residential and commercial use?

The primary type of wastewater treated in facilities serving both residential and commercial needs is sanitary or wastewater. This category encompasses the used water generated from activities such as flushing toilets, showering, laundry, and food preparation, making it a critical aspect of public health and environmental protection.

Sanitary wastewater includes a mix of human waste, household chemicals, and food particles, and it requires specialized treatment processes to remove pollutants and pathogens before the water can be safely released into the environment or reused. Treatment facilities are designed specifically to handle these wastes, ensuring they meet regulatory standards for safe discharge.

Stormwater, while important in the context of urban planning and environmental management, consists of rainfall or melted snow flowing over surfaces and typically has different treatment standards and methods focused on managing runoff rather than treating sanitary waste.

Industrial discharge refers to wastewater produced from industrial processes, which often contains specific pollutants and is treated in separate industrial facilities tailored to handle those contaminants.

Ballast water is primarily associated with ships and marine operations, involving water used to maintain stability and balance in vessels, and is regulated under maritime environmental laws rather than being part of standard wastewater treatment in municipal facilities.

Overall, the focus on sanitary or wastewater treatment reflects the need to effectively manage the public health risks associated with human waste and
