For placement sites of dredged material, Plains Dredging constructs earthen containment dikes or installs the innovative IMS GeoPool® dewatering system. Both options are reusable solutions that make the process of sludge containment easier and more manageable. Both systems accept the direct discharge of slurry from hydraulic dredges or any installed pumping system, and both bypass the expense of geotextile bags and the necessary polymer injections, which also require constant monitoring to ensure proper dosing for effective dewatering.
Natural earthen dikes are the most significantly cost-effective solution for the containment and dewatering of dredged material. An earthen dike requires only standard equipment, which makes it quick and easy to construct a basin from the dirt of the containment field itself. Built to any size, an earthen dike sufficiently accepts and contains any volume of slurry pumped in from hydraulic dredges or an installed pumping system. We use the earthen dike containment and dewatering solution 90% of the time, because most of our clients prefer the lower expense and the ease of use. We can easily create a secondary basin where sediment can settle and remain stored until removal.
The IMS GeoPool dewatering system is literally a groundbreaking innovation that requires no expensive bags and reduces the manpower needed by other dewatering systems. It is a reusable, scalable system that, like an earthen dike system, accepts sludge discharge directly from hydraulic dredges or pumping systems. Two pools can be used side by side for continuous dredging and dewatering. By connecting the two with a knife gate splitting system, the valve diverts slurry to a second pool once the first one is full.
The IMS GeoPool dewatering system, which resembles an above-ground swimming pool, is constructed with corrosion-resistant steel frames. The system provides fabric filtering options for separating silt, sand, vegetation, clay, and mine tailings. During the dewatering process, the filters allow the water to separate from the sludge and permeate into a system of gates that can be opened to allow the bulk release of clear water back to its source. After the dry down, front loaders or excavators can remove the dry cake to be hauled away, stored, used for land reclamation, or building earth walls. Once the dry cake is removed, you simply close the gates and restart the pumping process, with no need to replace the fabric filters.
