Storm sewer design
Storm sewer design is the development of a piping, ditch or dry-well system for disposing of storm water.
In most cases, storm water design will incorporate storm water management elements.
Storm sewer systems are almost always gravity-flow systems due to the large quantities of storm water. Storm sewer systems collect water form streets, roofs and other sources.
About 15% of communities in the United States have a combined system that handles both sanitary waste water and storm water in the same piping system. Oregon is one of the few states that has such communities.
