Map of Seattle sewer districts, 1894. The main part of such a system is made up of large pipes (i.e. the sewers, or "sanitary sewers") that convey the sewage from the point of production to the point of treatment or discharge. Sewers under construction in Ystad, Sweden. Types of sanitary sewer systems that all usually are gravity sewers include:

These relief structures, called "storm-water regulators" (in American English - or "combined sewer overflows" in British English) are constructed in combined sewer systems to divert flows in excess of the peak design flow of the sewage treatment plant.
