silt barrier fence
A silt barrier fence, also known simply as a silt fence or sediment fence, is a temporary sediment control device used in construction and landscaping projects to prevent sediment runoff from leaving the site and entering nearby water bodies or stormwater systems.
Typically, a silt fence consists of a permeable geotextile fabric stretched between wooden or metal stakes driven into the ground. The fabric is positioned downslope from disturbed soil areas such as construction sites or earthworks to intercept sediment-laden runoff.
The primary function of a silt fence is to slow down the flow of water, allowing sediment to settle out while the water infiltrates through the fabric. This helps to reduce erosion and sedimentation in adjacent areas, protecting water quality and preventing environmental damage.
Silt fences are often installed in conjunction with other erosion control measures such as sediment traps, sediment basins, or vegetative buffers to provide comprehensive sediment control on construction sites or areas with significant soil disturbance.
Regular inspection and maintenance of silt fences are essential to ensure their effectiveness. This may include repairing any damaged sections, removing accumulated sediment, and adjusting the fence as necessary to maintain proper alignment and tension.
Overall, silt barrier fences are valuable tools for managing sediment runoff and promoting environmentally responsible construction and land management practices.
