Broken Turbidity Curtain
Turbidity Barrier Repair
Problem: A customer contacted us looking for a solution to take out an existing broken floating turbidity curtain and remove the large amount of accumulated silt and sediment at the same time. With each new storm, the sediment would escape past the broken curtain and turbid the whole lake. The contractor needs to take out the broken turbidity curtain and remove the existing accumulated sediment before continuing with the new turbidity barrier installation.
Solution: Before removing the broken turbidity curtain or installing new floating turbidity barriers, the sediment build up should be cleared from the bottom of the waterway. Once the silt is removed from the site, new floating silt curtains should be in place before removing the broken turbidity curtain. The new floating turbidity barriers will keep any turbid water from spreading during the extraction.
The most efficient way of removing accumulated sediment is through the dewatering process. Dewatering Bags are deployed along the bank of the pond or river, placed in such a way the effluent flows toward the original body of water. Using a trash or debris pump, the sediment mixture is sent to the dewatering bags. The silt and sediment remain in the bag, while clean water flows out. Once the dewatering bags are 85 percent full of sediment, they are transported away from the site for disposal or used as compost. This process continues until the sediment build up near the broken turbidity curtain is gone.
