Summary Combined sewer systems are sewers that are made to gather rainwater runoff, domestic sewage, and industrial wastewater in one pipe. Most of the time, combined sewer systems bring all of their wastewater to a sewage treatment plant, where it is treated and then released to a nearby water body. However, when there is heavy rainfall or snowmelt the wastewater volume in a combined sewer system can exceed the capacity of the sewer system or treatment plant. And because of this, combined sewer systems are designed to overflow sometimes and release excess wastewater directly to streams, rivers, or other water bodies.
