IAI utilized an 8 inch diameter auger dredge to remove 25,000 cubic yards of coal ash (or fly ash) sludge from an industrial settling pond at a coal-fired electricity generation plant in Lumberton, North Carolina. The coal ash was dredged directly into geotextile tubes, which were deployed around the perimeter of the same pond. The filled geotextile tubes, … [Read more...]
IAI provides hydraulic dredging services for lagoons, impoundments, ponds, rivers and lakes. IAI has self-performed environmental and maintenance dredging projects, with or without dredged material dewatering and water treatment services. See examples of our project work here.
IAI was responsible for dredging approximately 20,000 cubic yards of coal ash (or fly ash) from a pond at a power plant in Tonawanda, New York. Hydraulic dredging of the 7.3 acre pond was completed over a 5 week period. The dredged material was dewatered using a Total Clean System. Effluent from the Total Clean unit was injected with polymer, then allowed to … [Read more...]
Scope of Work IAI was contracted by the Lake Sinissippi Improvement District to dredge the lake, and design and install an erosion control berm which would isolate a 40-acre portion of man-made Lake Sinissippi from an adjacent wetland. The project was conducted to remediate the marsh wetland environment, which had been deteriorated by a non-game fish … [Read more...]
IAI was contracted to remediate two ponds at the site of this former wood-treating facility. The ponds contained a layer of thick, black oily sludge, contaminated with creosote, polyaromatic hydrocarbons and metals, which had to be removed. To remediate the ponds, IAI removed the oily sludge with a submersible pump, and dewatered the slurry in geotextile … [Read more...]
IAI hydraulically dredged about 18,000 cubic yards of industrial process biosolids from two wastewater treatment lagoons, utilizing a cable-driven 8 inch diameter auger dredge. The dredged sludge was conditioned with flocculating chemicals and dewatered in about 2,400 lineal feet of 75 foot circumference geotextile tubes. The geotextile tubes were stacked in … [Read more...]
