Combined Sewage System

A Combined Sewage System is an infrastructure where both wastewater from homes, businesses, and surface runoff from streets are collected in a single network of pipes. During normal conditions, it transports sewage to treatment plants for cleaning. However, during heavy rain or storms, the system may overflow, releasing untreated mixture of rainwater and sewage into nearby water bodies. This system is efficient for areas with limited space but can pose environmental health risks during overflows. Proper management and upgrade of these systems aim to minimize pollution and protect water quality.
