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.
For calm water conditions this Type I barrier makes an excellent choice for silt and sediment control and meets regulatory requirements.
Fastwater Screen Type II is a durable premium silt curtain for rivers, streams, and lakes where moving water, winds, and waves are present.
Ruffwater Screen Type III is a heavy duty Premium silt curtain for use in tidal areas or areas where adverse conditions can occur.
Turbidity Curtains, or Silt Curtains, Silt Barriers, or Turbidity Barriers, as they are sometimes called, are floating barriers used in marine construction, dredging, and remeditation projects to control the silt and sediment in a body of water. Elastec Turbidity Curtains can be set up to keep construction areas in compliance and protect the environment. Click here for application questions.
The implementation of the Clean Water Act and Phase II of the National Pollution Discharge Elimination System (NPDES) has led to major changes in operating procedures for the industrial sector. It has encouraged major product development by Elastec in order to keep up with our customers needs and allow them to remain in compliance with these regulations.
