Combustion coal residuals (CCR) are often removed from a coal ash pond at a power plant by hydraulic dredging or excavation.
C&M Dredging works with each facility to manage CCR removal projects, whether to increase storage capacity in active ponds and basins or for closure purposes. We accomplish this through hydraulic or mechanical dredging, utilizing various dewatering methods.
Settling ponds and Lagoons are used in various industries and municipalities to remove solid particles and contaminants from wastewater. Dredging to remove this accumulated material improves the quality of the discharged water and preserves a settling pond’s effectiveness and storage capacity.
Site development dredging involves excavating the bottom of a body of water to create or enhance a site. This service is typical for constructing harbors, marinas, ports, and other waterfront developments. Although often overlooked, in-shore land developers can also capitalize on the benefits of this type of dredging.
Hydraulic dredges are use to remove tailings, increasing freshwater storage capacity and aiding in future reclamation activities. Mine tailings can then be pumped to an offline pond, spoil pit, or dewatered for on-site placement or export.
C&M Dredging has successfully performed various environmental restoration dredging projects for both public and private clients. Unlike dredging for navigational improvement, environmental restoration dredging is typically performed with a single goal: improving the quality of a water body.
Local, State, and Federal government agencies (and private entities) are tasked with maintaining a set channel depth that changes from location to location to ensure safe passage for vessels navigating the area without running aground.
Geotextile tubes are utilized on a hydraulic dredging project to contain and dewater sediments, making them suitable for transport and disposal. One key benefit of this method is its efficiency in removing water from large volumes of suspended material.
