Which of the following is the primary purpose of a wastewater treatment plant?

The primary purpose of a wastewater treatment plant is to clean wastewater before it is discharged into the environment. This process is essential for protecting public health and the environment. Wastewater treatment removes harmful pollutants, pathogens, and contaminants from water generated by households, industries, or storm runoff, ensuring that the water released is safe and can be returned to natural water bodies or used for other purposes.

By effectively treating wastewater, facilities reduce the risk of disease, environmental damage, and contamination of drinking water sources. The treatment typically involves several stages, such as screening, aeration, sedimentation, and disinfection, to ensure that the final effluent meets strict regulatory standards for quality. This focus on cleaning wastewater is crucial to maintaining sustainable water resources and protecting ecosystems.
