IAI utilized an 8 inch diameter auger dredge with an 8 inch inline booster pump to remove 20,000 cubic yards of solidified coal ash from a runoff water management pond at a coal fired electricity generation plant in Mississippi. Runoff from an adjacent coal ash pile had carried ash waste into the pond and had reduced the depth of the pond. A temporary … [Read more...]
During this project, 14,000 cubic yards of contaminated sediment was hydraulically dredged from a former borrow pit and dewatered in geotextile tubes. An existing asphalt parking lot was converted into a geotextile tube laydown area with the installation of temporary sand berms and a high density polyethylene (HDPE) liner. Eighty foot circumference … [Read more...]
