What is the main objective of sewage treatment?

The main objective of sewage treatment is to transform wastewater into reusable water and minimize environmental impact. This process involves several stages, including the removal of solids, pathogens, and pollutants from sewage before it is released back into the environment or returned for reuse. By achieving this goal, sewage treatment not only protects public health but also conserves water resources and reduces the environmental footprint of human activities.

The treatment process ensures that harmful substances are broken down or removed, thus making the treated water safe for discharge or even for purposes like irrigation, industrial processes, or replenishing groundwater supplies. This focus on transforming wastewater highlights the importance of both resource recovery and environmental stewardship in contemporary sewage treatment practices.
