A wastewater containment system begins by collecting wastewater through sewer networks or individual septic tanks. The collected wastewater may be transported to a centralized treatment facility or undergo on-site treatment, including screening to remove large solids, sedimentation to separate smaller particles, and biological treatment to break down organic matter using microorganisms.
Additional steps like disinfection and filtration may also be employed to remove pathogens and further purify the water. The treated water is then discharged into receiving bodies or reused for various purposes such as irrigation or industrial processes.
