Fast, Dirty Water

Sediment is one of the most persistent problems in stormwater management. This article discusses some of the issues involved in erosion control. Existing natural vegetation is one of the least expensive and most effective best management practices (BMP) available for limiting erosion. However, sediment control alone is ineffective. Other management tools and resources must be used, both before and after the problem arises. Stormwater control practices can be complex. Runoff volumes, velocity and rates also can be hard to predict. Also, tight stormwater restrictions have made implementation of BMPs increasingly important. When it comes to the removal of sediment from stormwater, there are several products available that are designed to handle sediments. The amount of sediment-carrying water that must be managed can be reduced by diverting and conveying flowing water around, under and over a work area. In addition, the removal of chemicals and oil from the water is also vitally important and must also be considered a best practice. The goal should be that the material coming through the unit will outlet to a stream or a natural waterway with the same type quality of rainwater that initially hit the ground.
