Type III Ruffwater Screen Turbidity Curtain (Specifications) is a heavy duty premium barrier for use in tidal areas or areas where adverse conditions can occur. It is designed for use in demanding water conditions. The curtain intercepts debris and slows the movement of rough water, helping to keep marine habitats safe. View DOT requirements by state.

Tell Us More About Your Project

RuffWater Screen is the toughest turbidity curtain for sediment and silt control to protect fragile environmental conditions. The California Depatrment of Transportation’s (CALTRAN) Crissy Field Drainage Improvement Project installed the RuffWater Screen to mitigate silt and turbid water in the construction zone. This project has received several environmental awards and recognitions. This curtain is well suited for the construction of bridges, intakes, and pipelines. It is available in permeable and impermeable options.

Elastec Type III Ruffwater Screen used near Golden Gate Bridge

Elastec Type III Ruffwater Screen was installed near the Golden Gate Bridge in San Francisco, CA. as part of the Crissy Field Drainage Improvement Project. Duane Bennish and Bill Andrus of the Cocoa branch were on site to help with the installation.

There was an existing drainage pipe that extended out into the water, but over time, the beach widened and the pipe was getting sediment in it and becoming blocked. It was difficult to clean out, so the remedy was to extend the outfall back out into the water.

Extension of the pipe will increase drainage capacity, reduce sand build up, and alleviate flooding issues. A “U” shape of curtain encompasses the worksite so that any disturbed sediment will not pollute the surrounding water, wildlife, and marine life. The install was high profile and was monitored by the media, California DOT, and marine biologists. Crissy Field falls under the National Park Service jurisdiction.
