Combined Sewer

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:

    I am absurdly fearful about this voyage. Various little omens have combined to give me a dark feeling.... Perhaps we shall live to laugh at these. But in case of mishap I should perish with my husband and child, perhaps to be transferred to some happier state.
    Margaret Fuller (1810–1850)
