Wastewater systems are designed to collect, treat, and dispose of used water from homes, industries, and businesses. This water, known as wastewater, can contain various contaminants that need to be removed before it can be safely released back into the environment. The treatment process typically involves several stages, including screening, sedimentation, and filtration. These steps help to remove solids and harmful substances, ensuring that the treated water meets safety standards. Once treated, the water can be returned to natural water bodies or reused for purposes like irrigation or industrial processes.
