2. What Is Combined Sewer Overflow (CSO)?
A combined sewer overflow (CSO) is a point where a
combined sewer system discharges untreated or
partially treated sewage and stormwater into nearby
rivers or streams.
This occurs when the system becomes overwhelmed
by heavy rainfall or snowmelt, exceeding its capacity
to handle the flow.
