Combined Sewer Overflows (CSO’s)
Stormwater discharges are often managed with the use of control structures known as CSOs. These structures are designed to limit stormwater flows to treatment plants by diverting a portion of the flows to directly to riverine or coastal receiving waters.
CSOs are designed to function during periods of high flow. Thus, protecting the property of people located upstream of the structures and limiting treatment plant flows. Since the use of CSOs can have a negative environmental impact; it is important to design these structures to limit the amount of waste material that is carried back into the environment without treatment.
Blue Hill Hydraulics uses CFD to improve the performance of existing CSO structures and to design innovative new ones. The results shown on here are from a study that involved the largest CSO located beneath Prague, the capital city of the Czech Republic.
