Sewer systems are underground networks designed to transport wastewater and stormwater away from homes and businesses. They help prevent flooding and protect public health by safely directing waste to treatment facilities. These systems consist of pipes, manholes, and treatment plants that work together to manage and process sewage. There are two main types of sewer systems: sanitary sewers, which carry wastewater from toilets and sinks, and storm sewers, which handle rainwater and melted snow. Proper maintenance of sewer systems is essential to ensure they function effectively and to prevent blockages or overflows that can lead to environmental issues.
