Sanitary Sewer Overflow Solutions

Vincent D. Reynolds, MBA, P.E.


Course Outline

SSOs occur when a number of problems occur in the sanitary sewer system. Those problems include clogs to the pipes from FOG, roots, pipe failures and pump failure. Infiltration can also be a problem that causes SSOs, especially during heavy rainfall.  This course will discuss the SSO solutions that could be implemented to control or eliminate SSOs. The course materials are based solely on the Environmental Protection Agency document “Sanitary Sewer Overflow Solutions” as found on the website of the Ohio Environmental Protection Agency.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of course materials.
