A sewage treatment plant is a facility designed to remove contaminants from wastewater and make it safe for discharge or reuse. It plays a vital role in protecting public health and the environment by preventing pollution of water bodies. The treatment process typically involves primary, secondary, and sometimes tertiary stages to filter out solids, organic matter, and harmful microorganisms. Modern plants use advanced technologies like membrane filtration, UV disinfection, and anaerobic digestion to enhance efficiency. These systems support sustainable water management and help conserve freshwater resources. Investing in sewage treatment infrastructure is essential for growing communities and a cleaner, greener future.
