A combined sewer is a type of sewer system that collects sanitary sewage and stormwater runoff in a single pipe system. Combined sewers can cause serious water pollution problems due to combined sewer overflows, which are caused by large variations in flow between dry and wet weather. This type of sewer design is no longer used in building new communities, but many older cities continue to operate combined sewers.

Famous quotes containing the word combined:
“Today we all speak, if not the same tongue, the same universal language. There is no one center, and time has lost its former coherence: East and West, yesterday and tomorrow exist as a confused jumble in each one of us. Different times and different spaces are combined in a here and now that is everywhere at once.”
—Octavio Paz (b. 1914)
