ABSTRACT

Sump manholes are common structures used by municipalities as access points to storm sewers. But as anyone who has opened a manhole lid to a sump knows, sediment and debris collects in them. Engineers at the Minnesota Department of Transportation asked, “How effective are standard sump manholes as stormwater treatment devices, and can we make them more effective?” To answer this question, SAFL researchers invented the SAFL Baffle, a retrofit device that significantly boosts the performance of sump manholes as stormwater best management practices (BMPs).

In this thesis defense, you will learn how the SAFL Baffle will perform when:
Clogged with debris like trash and vegetation
Installed in a sump with an outlet pipe 90 degrees to the inlet pipe
Installed in a sump with water entering through an inlet grate and inlet pipe
