drainage system
Quick Summary
A sewerage system is a network designed to collect and transport wastewater, or sewage, from a community. These systems are categorized into domestic and industrial sewers, and storm sewers. Some systems combine both, while others use separate networks for domestic/industrial waste and storm runoff.
Domestic and industrial sewers carry wastewater that is typically treated before discharge. Storm sewers manage surface runoff, which may be directed to detention basins or directly to streams and rivers. Modern systems increasingly favor separate networks to optimize treatment and management processes. Alternative systems like small-diameter gravity sewers, pressure sewers, and vacuum sewers exist for areas where conventional gravity sewers are impractical due to cost or site conditions. The primary goal of these systems is to safely convey waste for treatment and disposal, protecting public health and the environment.1234
