Most in the construction industry are familiar with the basic sediment control tools, such as silt fence and inlet protection. However, sometimes we are challenged with unique and extraordinary sediment trapping challenges. A project at the bottom of a large watershed receives floods of storm water from offsite. Hydro-excavation generates sediment laden water that is off the charts of any turbidity meter. Pipe jacking next to a popular stream produces a clay-slurry that cannot be released. Contaminated sediments are especially challenging because the sediment-filled water can spread the area of contamination. Case studies will be presented to show how projects ramped up sediment control in these situations to meet permit requirements.
