Type 3 Turbidity Curtain

The DOT type 3 silt curtains are specifically designed to meet the compliance requirements of the Department of Transportation (DOT). For states or projects with unique environmental regulations, One Clarion offers custom-engineered barriers to meet your city or project’s exact specifications. All Floating Barriers are constructed to align with DOT standards and project needs.

DOT Type 3 barriers are commonly used by Transport Infrastructure agencies during road, rail, and bridge construction near fast-flowing or rough water. These curtains effectively contain disturbed silt and debris, preventing it from migrating beyond the work zone and impacting surrounding ecosystems. With a Type 3 turbidity curtain in place, sediment is allowed to settle, while floating debris can be skimmed from the surface, supporting cleaner waterways and regulatory compliance.

The HD turbidity barriers are the strongest silt curtains available, engineered specifically for the most demanding environments, including areas with high winds, strong currents, and heavy wave action. Due to their enhanced durability, HD curtains must be paired with high-performance Marine Accessories and reinforced installation hardware for secure anchoring and reliable deployment.

For coastal cities with harbors and marinas impacted by frequent wind and wave activity, the HD turbidity curtain offers robust protection. It helps contain sediment and silt, reducing environmental impact, while also serving as a barrier to algae and invasive aquatic vegetation entering sensitive bay or shoreline ecosystems.

As our strongest filtering turbidity barrier, the Type 3 permeable HD turbidity curtain is engineered to both retain sediment and allow water to flow through. This dual-purpose design reduces hydraulic pressure on the curtain, enhancing its durability, longevity, and operational performance in high-energy water environments.

TThe HD Type 3 permeable curtain is frequently deployed around municipal dams where water flows continuously at high velocity. It enables effective turbidity control without disrupting the necessary flow rate, making it a preferred solution for Water Management departments overseeing sensitive dam operations.
