Separate sewers are a type of wastewater management system designed to keep stormwater and sewage separate. In this system, rainwater from streets and roofs flows into one set of pipes, while household wastewater from toilets and sinks flows into another. This separation helps prevent sewage overflow during heavy rain, protecting water quality in nearby rivers and lakes. The main advantage of separate sewers is improved public health and environmental safety. By reducing the risk of contamination from combined sewer overflows, separate sewers help maintain cleaner water in natural bodies, benefiting ecosystems and communities. This system is often used in urban areas where heavy rainfall can overwhelm combined sewer systems.
