MDG offers wide-ranging fluid management, tailings management and dredging services. Our talented team has extensive experience in the industry, allowing us to provide innovative contract dredging, dewatering, dredge and pump sales and system installation services. Additionally, we provide onsite training, after-sales support, customized designs, and equipment rentals.
As a company, MDG delivers a complete package that encompasses launch, commissioning and operation, as well as civil construction services for coal combustion residuals, mining, hydro, environmental, and industrial applications. We understand the unique challenges and constraints each application presents and ensure that we deploy the best team and equipment for the project.
DREDGING APPLICATIONS
COAL COMBUSTION RESIDUALS (FLY ASH)
Specializing in the hydraulic and mechanical excavation of fly ash containment ponds, MDG can transfer medium to large volumes of fly ash to final containment sites. Breaking away from traditional methods, MDG provides customized fly ash remediation solutions for each project that are environmentally sound, community friendly, cost-efficient and risk reducing. Our team is committed delivering optimal results through the engineering, procurement, construction and management of each project’s life.
POWER/ENERGY
Power plant operators can depend on MDG for sediment removal in mission critical water flow processes. Power plants require an uninterrupted upstream source of water for both power generation and process cooling. With downstream these same types of sediments must be removed to allow for channel navigation and other requirements. MDG can remove fly ash from coal-fired power plants and sediment accumulation from hydroelectric dams, restoring storage capacity limits. We customize our dredges for each project’s specifications including dredging depth, material removal rate, and automation.
ENVIRONMENTAL
MDG has a history of being utilized for the biological cleanup of harbors, rivers, and lakes. Additionally, MDG can remove industrial chemical runoff and submerged contaminated sediments from natural and man-made waterways and spill areas. As an industry leader in environmental remediation, our state-of-the-art equipment allows us to design our dredges to minimize, if not eliminate, further contamination risks.
MINING
For mining and tailings management applications, water is an essential resource. By processing the material in tailings ponds, MDG makes water available for recycling. Dewatering mine sites can assist with production schedules by using a fleet of self-priming diesel pumps. MDG has the experience necessary to control water levels of underground water bodies that are close to tailings dams.
INDUSTRIAL
MDG’s systems solutions are the commercial standard for industrial lagoon maintenance. When sediment holding areas reach or exceed their design capacity limits, experts turn to MDG for the most efficient and cost-effective method to reclaim the site’s original storage capacity. MDG’s dredge system allows for efficient and cost-effective storage capacity reclamation. Whether the material is benign or contaminated, MDG’s dredging systems can successfully restore these industrial lagoons. Our specialization extends to explosion-proof dredges and wireless dredge automation.
