[0002] Rainwater and sewage separation is a drainage system that separates rainwater and sewage, each transported through its own pipeline for discharge or subsequent treatment. Rainwater is discharged directly into rivers through a rainwater pipe network, while sewage is collected through a sewage pipe network and sent to a sewage treatment plant for treatment, preventing sewage from directly entering rivers and causing pollution. Furthermore, the collection, utilization, and centralized management of rainwater discharge reduces the impact of water volume on sewage treatment plants, ensuring their treatment efficiency.
