Overview
This course provides an integrated approach to manage the solids generated in urban wet weather flows, both on the land surface and in drainage sewer systems. Threats to the quality of receiving waters by discharges from urban-storm- generated WWF, including combined sewer overflow and polluted runoff from urban streets, are well known. During many storm events, large volumes of stormwater are drained via street inlets into the urban sewer system. The storm runoff washes off street dust-and-dirt and pollutants from catchment surfaces into the sewer system.
In this course the student will learn about sources of sewer sediment and the impact of those sediments, methodology for quantifying sediment-solids in sewer systems and sediment control methods.
The student is expected to read and review the material contained in the Sewer Sediment and Control – A Management Practices Reference Guide, EPA/600/R-04/059 – January 2004.
The student must take a multiple-choice quiz consisting of twenty-five (25) questions at the end of this course to earn PDH credits.
