Turnkey CCR Dewatering and Treatment

CCR Dewatering and Treatment

Combining CCR dewatering and water treatment under a single contractor is the single best way to minimize risk, protect the schedule, and limit costs during a coal ash pond closure project. GWTT’s white paper on integrating these two critical and interdependent activities explains the benefits in great detail and is available upon request:

GWTT Delivers Turnkey CCR Dewatering and Treatment 

GWTT’s turnkey approach bundles the dewatering of ash ponds with the treatment of the pond water into a single solution for your pond closure projects. We offer our clients schedule-sensitive and regulatory-compliant solutions for their most challenging projects. We have successfully treated more than 2 billion gallons of  CCR site pond water, including bulk surface water and the interstitial “pore” water.

GWTT partners with our clients and their engineering teams to tailor a dewatering and treatment system to address all aspects of a specific project site. We start with source water characterization and treatability studies, and then work through the design, installation, operation, and maintenance of customized treatment systems, including ongoing compliance testing and monitoring.

The video below demonstrates the advantages of integrating CCR dewatering and treatment under a single service provider.

Using our advanced subject-matter expertise in water chemistry, GWTT delivers custom engineered treatment systems specific for total metals, with a focus on the reduction of arsenic and selenium (which are difficult to treat with traditional water treatment techniques) for the required effluent discharge criteria.

Unlike other remediation contractors that outsource large portions of the work, GWTT self-performs substantially all aspects of each project. This vertical integration allows us to offer an unmatched quality assurance guarantee and deliver overall project success. Let us be part of the solution to your coal ash pond closure project.

GWTT Coal Ash Pond Remediation Solutions

Coal Ash Pond Water Remediation

We have experience treating more than 2 billion gallons of CCR and related pond water with project-specific treatment systems designed for arsenic, selenium, thallium, and other metals that are difficult to treat with traditional water treatment techniques. GWTT has designed and installed pontoon systems for decanting surface water, collection systems for removing and treating interstitial water, and groundwater collection and treatment systems to carry the project to closure. We have designed and built CCR water treatment systems that handle influent flow rates of 50 GPM to 15,000 GPM.

Ash Dewatering

GWTT maintains an extensive inventory of pumping equipment, filtration systems, and treatment technologies that can be easily mobilized to meet the immediate needs of the project, whether it is a clean closure or a close-in-place. Our design team can customize a dewatering system to support the construction team, maintain the schedule, and ensure that the ash stability meets all project specifications.

Landfill and Leachate Collection Systems

Our technology and engineering team can construct, install, and start up landfill leachate collection systems, to manage dry ash systems, wet ash systems, landfill closure requirements, and other wastewater collection systems throughout the facility. We can design and operate a system to meet the discharge limits as required by permit.

Operation & Maintenance (O&M) of Treatment Systems

GWTT employs a highly-qualified staff of O&M Operators and Technicians with experience specific to CCR water treatment processes. The GWTT approach to system O&M is project specific and carefully evaluated to determine the appropriate level of staffing required, while also being considerate of project economics.
