Turbidity Control Barrier For Dredging Job
Bidding On A Turbidity Barrier Job For A Pond
Question regarding a turbidity control barrier. We are bidding a town job requiring turbidity control for a pond. I am assuming the curtain is acceptable and because it is not a DOT project we would use standard. Do you have estimated pricing per foot? We are looking at the silt curtain Type 1 Economy. we are dredging 7,500 square feet.
Water is a NH pond with no use - dredging for a fire pond. Approximately 75' in length. The plans do not specify. Is 5' standard? Also - this is literally a stand alone pond. Is the Type 1 Silt Barrier the most cost effective? Please quote the 50' length and the 100' length. I'm not sure which one they'll decide to use. A few other questions. Can these be reused? Do you provide the anchors and all items needed to install?

Answer: Thank you for asking. Since your project is is being implemented in a stand alone pond, the Type 1 Turbidity Barrier can be a reliable choice for this type of turbidity control. Type 1 barriers are designed specifically for water areas that have calm or non-moving waters. They are not designed for areas with any kind of a current or waves.
Standard Silt Barrier Sizes and Uses:
The standard silt barrier will be made with a length of either 50 or 100 feet. Standard depths for these barriers are 5 feet, although depths can vary depending on your water location. Typically you will want any barrier you use to sit about one foot from the floor of your water body. This helps to prevent barriers from getting trapped or stuck during use.
If your project is not a DOT project and does not require a barrier that meets DOT regulations, the Type 1 Economy barrier is by far the most economical.
Regardless of type, all barriers are typically capable of being reused. You will, however, want to make sure that the barriers are properly cleaned before reuse. Especially when used a contaminated area, barriers should be cleaned of turbidity and silt to prevent contamination to a new site.
On the Type 1 Silt Barrier there should be no anchor points, making any kind of anchoring system unnecessary. Since the water used for your barriers should not be moving, the turbidity control barriers should generally stay in place without any extra anchors.
If you are looking to further secure the barrier, rope and concrete filled buckets or cinder blocks can be used to keep the barrier in place.
