Omega Mine extends AMD treatment capacity with dewatering
At Omega Mine in West Virginia, GEOTUBE® GT500 units help the West Virginia Department of Environmental Protection treat and dewater acid mine drainage from abandoned mines while supporting long-term capacity and compliance.
Dredging and reuse of contaminated sediments
Embraport used dewatered contaminated sediments as structural fill within its terminal platform, saving 400,000 m3 of imported material and reducing earthfill platform costs by 20% to 30%.
Remediation of contaminated marine sediments at Port Ouest, La Grande-Motte using GEOTUBE dewatering systems
Contaminated sediments were dredged from Port Ouest in La Grande-Motte and dewatered using GEOTUBE technology to support port modernization while meeting environmental requirements.
To improve riverbed conditions through sediment management, the Schwarze Elster River near Elsterwerda and Plessa, Germany, required the removal of approximately 10,000 m³ (13,080 yd³) of sediment. Commissioned by Gewässer und Bodenverband “Kleine Elster–Pulsnitz”, the Schwarze Elster project was completed by Limus Dredging between June 2025 and September 2026.
The project needed a combination of dredging and geosynthetic dewatering technology to deliver an effective and practical solution for sediment removal, secure containment, and water separation.
Considering the large volume of dredged material needing appropriate management, operational flexibility was an important factor that a proposed solution would need to accommodate. Limus Dredging also preferred a product with which it had previous experience, supporting efficient installation and operation. Efficient water release is essential in dewatering activities, though safe containment of dredged sediments was one of the project requirements.
The Schwarze Elster project selected GEOTUBE® dewatering tubes, supplied in a variety of lengths with an 18.3-meter circumference, the system provided the dewatering performance, storage capacity, and operational flexibility required for the project.
GEOTUBE dewatering tubes were chosen for its storage capacity, safety features, effective filtration, and operational flexibility. The contractor’s previous experience with the product further supported successful implementation.
By combining performance and value, the GEOTUBE dewatering tube systems provide a cost-effective solution for dredged sediment dewatering while helping achieve the project’s sediment management objectives.
