You’ll most often see Type 1 turbidity curtains in places with milder conditions. Ponds, small lakes, and marshes are less likely to have the strong winds or currents that necessitate a higher level curtain. These can be entirely made of PVC, or may include a filtering, permeable window for water to pass through. These skirts can extend up to 100 ft, depending on the needs of your particular project.
A Type 1 DOT curtain has been specifically designed to meet the requirements based on Department of Transportation regulations. Their lightweight and more flexible design means these are often found in calmer waters like canals, reservoirs, and roadside conditions. These will have the least load capacity overall, and will have a lighter breaking point than the higher level curtains.
