Establishing the erosion control area
At the construction site for Pump Station #4 Force Main project in Washougal, WA, we installed a water- filled rubber berm around the first half of a trench across the Washougal River (actually two trenches each with two 14-inch utility pipes). The purpose of this was to contain the silt from the excavation.
