This presentation will focus on research completed to determine the trapping efficiencies of sediment basins of various designs installed on active construction sites across North Carolina. Because of the increasing sediment pollution from construction sites, concern for severe impacts on nearby streams is expanding . Controlling erosion is the most effective approach to reducing sediment loads, but construction sites typically have large areas of exposed soil during the active phase of clearing and grading. As a result, sediment traps and basins are required to capture eroded sediment on most of these sites.
Understand the importance of sediment control for water quality, and the importance of best management practices during construction.
Understand techniques used in good sediment basin design.
Understand the proper design, installation and maintenance of various components associated with sediment basins.
