Cincinnati's combined sewer system, which handles both stormwater and sewage in a single pipe network, was built for a much smaller population. During heavy rain events, the system reaches capacity and backflow can push sewage up through your home's lowest drains. Neighborhoods with older infrastructure, particularly in the basin near the Ohio River, face the highest risk. Tree root intrusion is also common across Cincinnati because mature trees like the American Sycamore and Ohio Buckeye send aggressive root systems into clay tile sewer laterals installed before 1975. These roots create blockages that cause toilet overflows without warning.
