Bradford Island – US Army Corps of Engineers

The US Army Corps of Engineers needed cleaning and videoing storm drain lines from a service building adjacent to a hazardous waste storage area on Bradford Island. Braun Construction had to figure out a way to jet the lines with water and not let the contaminated sludge or water drain from the outfalls and into the Columbia River. The drain lines were cleared by placing an inflatable plug in the outfall to prevent contaminates from polluting the river while jetting the drain lines with water. A vacuum truck was used, and the water and sludge generated was pumped into large roll off containers.
