How Do You Install A Type 2 Silt Barrier or Turbidity Curtain?

(Boisbriand, Canada)

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 accross and we are lookin at about 5 to 9 feet of water. It is going to be installed perpendicular to the flow accross 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?

Thanks for your inquiry. We are happy to answer your turbidity curtain installation questions!

The bottom of the Type 2 Silt Barrier has balast chain to pull the curtain down and it should have anchor points at about the water line. The anchor point is a line attached to a bouy or a rope to a chain and then to an anchor. Divers are unecessary for this type of installation. Boats may be needed to pull the curtain, as it will be heavy.

You may need to be carefull of the flow since the barrier may act as a big sail if the water level rises rapidly (ie strong flow). If you have an e-mail address I can send you a sketch to assist.
