If the system carries both domestic and storm-water sewage, it is called a combined system, and these usually serve the older sections of urban areas. For this proposal, as the cities expanded and began to provide treatment of sewage, sanitary sewage was separated from storm sewage by a separate pipe network, called the separate system. This arrangement is more efficient because it excludes the voluminous storm sewage from the treatment plant. It permits flexibility in the operation of the plant and prevents pollution caused by combined sewer overflow, which occurs when the sewer is not big enough to transport both household sewage and storm water. Certain types of sewers, such as inverted siphons and pipes from pumping stations, flow under pressure, and are thus called force mains....
