Sediment Control

Construction activities can disturb the ground at construction sites.  Excavating, bulldozing and other moving vehicles loosen the soil and can pollute the soil with various contaminants.  Rain can then transport soil based sediment, debris and pollutants, as well as runoff from stored material, into the nearby environment.

 

Controls are used to manage sediment runoff at construction sites.  Common sediment control techniques include detention ponds and filtration fencing.  Detention ponds are created in low spots to collect water runoff, giving the water time to settle before moving on free of sediment and debris.  Silt fencing utilizes a porous fabric that is held in place by burying the bottom part of the fabric and then stretching the exposed remainder of the fabric across posts, thus creating a “fence”.  Silt fencing catches downslope surface water, filtering out suspended solids before the runoff can exit the site.

 

Other sediment control methods include lined swales, erosion control mats, anti-tracking pads to remove soil from truck tires, and the placement of hay bales or silt socks around catch basins.

 

As part of the overall site plan, perimeter controls should be in place prior to clearing, grading or any other earth disturbing activities, and must remain in place until final stabilization has been established.

 

If sediment control is mismanaged, significant damages could be quickly created.  The experts at CED can help.  Call us at 1-800-780-4221 or visit here for regional contact information.
