a sewer system that carries both sewage and storm water runoff. Normally, its entire flow goes to a wastewater treatment plant, but during a heavy storm, the volume of water may be great enough to cause overflows of untreated mixtures of storm water and sewage into receiving waters. Storm water runoff may also carry toxic chemicals from industrial areas or streets into the sewer system.
a sewer that carries both storm water and sanitary sewage (wastewater from your drains and toilets) to a treatment plant for treatment
a system of single pipes that collect both wastewater from homes, businesses and industries as well as surface runoff from rainstorms and snow melt
Carries both sanitary sewage and storm water run-off.
A sewer designed to carry both sanitary wastewaters and storm-water or surface-water runoff.
A sewer system by which both storm water and sanitary wastes are transported by the same pipe to a sewage treatment plant.
A sewer that carries both sewage and street runoff
a pipe or sewer that carries both wastewater and rainwater.
A sewerage system that carries both sanitary sewage and stormwater runoff.
A sewer designed to carry foul sewage and surface runoff in the same pipe.
A sewer that transports surface runoff and human domestic wastes (sewage), and sometimes industrial wastes.
A sewer system that carries both sanitary waste and storm water runoff.
A Combined sewer is a type of sewer system which provides partially separated channels for sanitary sewage and stormwater runoff. This allows the sanitary sewer system to provide backup capacity for the runoff sewer when runoff volumes are unusually high, but it is an antiquated system that is vulnerable to sanitary sewer overflow during peak rainfall events.
