Broken Floating Turbidity Curtain

How To Take Out An Existing Turbidity Curtain and Take Care Of The Large Amount Of Accumulated Silt And Sediment?


Problem: Broken Floating Turbidity Curtain. A visitor contacted us looking for a solution to take out an existing broken floating turbidity curtain and taking care of the large amount of accumulated silt and sediment at the same time. With each new storm, the sediment would be suspended and turbid the whole lake. The contractor visiting our site had to take out the broken silt barrier and to remove the existing accumulated sediment before he could install new floating barriers.

Solution: Our Granite Environmental product specialists suggested first to install new barriers prior to removing the old silt curtain to avoid the turbid water being released.

After this there were different options for retrieving the existing broken turbidity curtain, depending on the water depth, the skirt size of this barrier, and the inches/feet of sediment on the barrier.

One possibility was to use a trash pump and "suck" the sediment from the base of the curtain and then pump it to dewatering bags or a settling area created in the pond. Alternatively, it could be tried flushing the sediment from the skirt by using a trash pump but this option would create turbidity. Learn more about our other silt curtain options.


Products Recommended

Products that were recommended for this type of barrier removal and control include the following:

  • Turbidity Barrier: The floating turbidity barrier is a floating device designed to contain silt, dewatering bagsediment and debris to a specific area. Barriers were recommended for installation around the existing barrier to prevent the products from spreading or causing contamination around your location.
  • Dewatering Bag: The dewatering bag is a commonly used BMP (best management practice) that is designed to filter out sediment or oil-laden water.

Water will be pumped into these bags, where it is then filtered. Clean water should start flowing from the bag, while sediment, silt and other debris are contained.
