What is a combined sewer overflow?
A CSO (combined sewer overflow) is a discharge from a combined sewer system which is a mixture of domestic wastewater and excessive rainwater in the same pipe.  A CSO may occur during heavy rainfall events when the amount of wastewater and rain exceed the capacity of the system.
