What is a common goal of wastewater treatment?

Improving water quality and protecting human health and the environment is a fundamental goal of wastewater treatment. This process is essential in removing contaminants such as pathogens, organic materials, heavy metals, and other pollutants from wastewater before it is released back into natural water bodies or reused. By effectively treating wastewater, treatment plants help ensure that the water returned to the ecosystem is safe for aquatic life and human use, safeguarding ecosystems and public health.

Maximizing the volume of wastewater stored would not align with the primary objectives of treatment, as storage does not address the removal of pollutants. Reducing the cost of water supply and increasing the profitability of water companies are more focused on economic aspects rather than the core objective of protecting the environment and public health through effective wastewater management. These alternatives do not capture the essential purpose of wastewater treatment, which emphasizes environmental sustainability and health improvements.
