SILT FENCING FOR EFFECTIVE SEDIMENT CONTROL
BEST MANAGEMENT PRACTICE
A silt fence serves as a temporary solution to control sediment at construction sites. It consists of a dense geotextile fabric network strategically placed in the path of water flow within the project area. The design and installation of silt fences are simple and cost-effective. Once implemented, they effectively halt the transfer of sediment from disturbed areas into nearby waterways. They also restrict the passage of waste materials from construction sites via stormwater runoff, thereby minimizing soil erosion. To ensure the continued efficacy of silt fences, regular maintenance is necessary.
|Construction Sites||Control sediment runoff and prevent soil erosion during construction activities|
|Road Construction||Mitigate the migration of sediment and debris into nearby bodies of water|
|Land Development||Manage sediment runoff and protect surrounding ecosystems while developing land|
|Stormwater Management||Filter sediment and debris from runoff to ensure cleaner water enters drainage systems|
|Restoration Projects||Control sediment movement and aid in the establishment of vegetation|

FREQUENTLY ASKED QUESTIONS
What is a silt fence?
A silt fence is a perimeter control device made of a geotextile fabric network designed to manage sediment runoff at construction sites and other areas prone to soil erosion.
How does a silt fence work?
A silt fence filters sediment-laden water, allowing it to pass through the fabric while trapping and retaining sediment. It helps prevent sediment from reaching nearby water bodies and protects against soil erosion.
Where are silt fences used?
Silt fences are commonly used in construction sites, road construction projects, land development areas, agricultural practices, mining operations, landscaping projects, stormwater management systems, restoration projects, pipeline and utility installations, and soil conservation efforts.
What are the advantages of using silt fences?
The benefits of using a silt fence include:
- reducing sediment runoff and soil erosion
- protecting water quality in nearby water bodies
- complying with environmental regulations
- preventing damage to aquatic ecosystems
- maintaining the stability of slopes and embankments.
How should a silt fence be installed?
Proper installation of a silt fence involves placing the fabric barrier in the direction of water flow, ensuring it is securely anchored to posts or stakes, and correctly overlapping and sealing the fabric sections. The fence should be positioned at a suitable distance from the disturbed area and properly maintained.
How often should a silt fence be maintained?
Regular maintenance is crucial for ensuring the effectiveness of a silt fence. It should be inspected regularly for damage, sediment accumulation, or clogging. Sediment should be removed, and any damaged sections should be repaired promptly.
