A sewer system is a network of pipes and infrastructure designed to transport wastewater and sewage away from homes and businesses. This system helps to prevent flooding and protects public health by safely directing waste to treatment facilities. Sewage is collected from toilets, sinks, and drains, and then flows through underground pipes. Once at a treatment plant, the wastewater undergoes processes to remove contaminants before being released back into the environment, often into rivers or oceans. Proper maintenance of the sewer system is essential to ensure its efficiency and prevent blockages or overflows.
