Speaker: Joseph Threadcraft, PhD PE

Topic: Combined Sewer Systems
Presentation: N.A.
Summary: Joseph Threadcraft, PhD PE will present on approaches to eliminate combined sewer overflows. Combined sewer systems use a single pipe to receive and transport wastewater and stormwater. During heavy rain events, the volume of stormwater entering the pipe exceeds infrastructure capacity and results in the discharge of untreated flows to receiving waters. The overflows that result from this design negatively impacts the receiving waters. The US EPA has indicated that nearly 860 municipalities in the US have combined sewer systems.
