Type 3 DOT Turbidity Barrier

type 3 DOT turbidity curtain

Type 3 DOT Turbidity Curtains:

Fast-Moving Water Conditions

When managing construction projects in challenging aquatic environments; such as rivers, bays, and tidal zones; effective sediment control is paramount. Our Type 3 DOT Turbidity Curtains are specifically designed to meet the rigorous demands of fast-moving water conditions, ensuring compliance with Department of Transportation (DOT) standards across various states. Constructed with high-strength materials, these heavy-duty turbidity barriers feature robust PVC-coated fabrics, reinforced tension cables, and durable flotation systems. This design ensures optimal performance in areas with strong currents, waves, and wind, effectively containing sediment and preventing environmental contamination.

Type 3 DOT Turbidity Barrier and Compliance

Maintain Regulatory Compliance in Fast-Moving Waters

Construction projects near or in water must meet strict regulatory standards. Our Type 3 DOT Turbidity Barriers are engineered to help you stay compliant with DOT, EPA, NPDES, and Clean Water Act requirements. Designed for fast-moving water, waves, and tidal conditions, these robust permeable turbidity curtains control and contain sediment; giving it time to settle naturally.


Effective Sediment Control for Demanding Environments

Floating turbidity barriers act as temporary containment systems. When the correct type, size, depth, and placement are selected, Type 3 DOT Turbidity Barriers efficiently detain sediment-laden water long enough for total suspended solids (TSS) to settle. These barriers are recognized as a Best Management Practice (BMP) by regulatory agencies but are not substitutes for permanent structures.


Benefits of Properly Applied Turbidity Curtains:

  • Temporarily contain suspended sediment
  • Allow particles to settle before dispersion
  • Comply with EPA and DOT regulations
  • Mitigate environmental impact in aquatic zones

Common Applications of Type 3 DOT Turbidity Barriers

Type 3 DOT Turbidity Barriers are among the strongest floating containment systems available. Suitable for water velocities up to 1.5 knots, they’re ideal for high-flow or open-water applications, including:

  • Bays and Lagoons
  • Marinas and harbors
  • Shoreline and tidal construction zones
  • Offshore dredging operations
  • Bridge and pier repairs
  • Environmental remediation projects

Type 3 DOT Turbidity Barrier is one of the strongest floating barriers available for controlling the turbidity of water. Use it for locations with flows up to 1.5 knots. Our sales team can answer all questions about our Type 3 DOT Turbidity Barrier, including turbidity barrier price, installation, and maintenance.


Engineered for High-Performance: Reinforced Filtration Skirts

Type 3 DOT Turbidity Barriers are constructed with both permeable and impermeable fabrics, featuring reinforced filtration panels (also known as filter skirts) sewn directly into the curtain. This dual-material approach offers two key advantages:

  • Filtration: Allows controlled water flow while trapping sediment.
  • Durability: Reduces pressure on the curtain in areas with high sediment load or strong currents.

This makes the barrier both stronger and more effective for sediment containment in aggressive water conditions.


Additional Options and Customization

We offer a full range of Type 3 Floating Turbidity Curtains tailored to different project needs:

  • Type 3 DOT
  • Type 3 Heavy Duty (HD)
  • Type 3 HD DOT

Bulk pricing and custom configurations are available to accommodate unique site specifications. We also provide DOT-grade turbidity curtains in Type 1 and Type 2 models for use in slower-moving water environments.


Because Type 3 turbidity curtain is designed for fast moving water, there are anchoring and deployment components necessary for proper installation. Browse our selection of Marine Accessories to find the right equipment for your curtain.
