Wastewater management refers to the process of collecting, treating, and disposing of wastewater, which is water that has been used in homes, industries, and businesses. This water can contain harmful substances, so it is essential to treat it before releasing it back into the environment. Effective wastewater management helps protect public health and the ecosystem by reducing pollution and conserving water resources. The treatment process typically involves several stages, including physical, chemical, and biological methods. Facilities known as wastewater treatment plants are designed to handle this process, ensuring that the treated water meets safety standards before it is returned to rivers, lakes, or used for irrigation.
