How Do You Install Type 2 Turbidity Curtain?

Installation of Silt Barrier Turbidity CurtainQuestion: How do you install a type 2 silt barrier? In particular, I have some questions on the installation of the type 2 silt barrier in a small stream. It is pretty dry for the moment but that can change. The river is about 70 feet across and we are looking at about 5 to 9 feet of water. It is going to be installed perpendicular to the flow across the river. Does it get anchored at the bottom or is it weighed down? I am not sure if we would need divers to install it or not. Does it need to be anchored?

Answer: We are happy to answer your turbidity curtain installation questions. The first thing we would like to recommend about your installation process is the direction in which you will be installing this barrier.

In general, it is typically recommended that the silt barrier be installed parallel to the flow. Depending on your location, installing the barrier perpendicular to the flow may cause unnecessary strain on your curtain. There are a couple of instances when you may want to install the silt barrier across the flow in a V format. For more information, please view Installing Silt Barriers Across Flows.

Anchoring the Bottom of Type 2 Silt Barrier

Due to the moving water conditions of the Type 2 Silt Barrier, it is commonly recommended that some form of anchoring be used to help keep the barrier in position.

Along the bottom of the Type 2 Silt Barrier is a ballast chain designed to weigh the curtain down. This chain should have anchoring points along the chain. At the anchor point, a line may be attached to a buoy, rope, or chain. This buoy/rope/chain is then attached to the anchor to keep the barrier in position (see image). Divers will be unnecessary for this type of installation, however, boats may be needed to pull or tow the barrier into position, as the barrier itself will be heavy.

Silt Barrier Considerations

You may need to be careful of the flow since the barrier may act as a big sail if the water level rises rapidly (i.e. strong flow). For more information, please see our Turbidity Curtain Installation Guide.
