Geotextile Tubes for Dewatering & Sludge Treatment

Geotextile dewatering systems filter suspended solids and pollutants from water before discharge, helping projects meet EPA stormwater and wastewater regulations. By containing sediment, concrete washwater, and other contaminants on-site, these systems prevent the discharge of harmful materials into waterways, storm drains, and drinking water supplies — a key requirement under NPDES permits.

Concrete washout bags are compact, portable containment units designed specifically to capture alkaline washwater from concrete trucks, pumps, and drums on construction sites. Geotextile tubes are larger-scale systems used for bulk dewatering of sludge and sediment. Both rely on geosynthetic filtration principles but are sized and configured for different volumes and site conditions.

Several dewatering products in our lineup, including the Road Drain Portable Sediment Containment System, are designed with reusability in mind. Replacement filters can be swapped out after each use, extending the system's service life and lowering long-term project costs. Concrete washout bags can also be transported intact to landfill or recycled after the concrete residue has solidified.

Geotextile dewatering solutions are widely used in construction, civil infrastructure, municipal wastewater treatment, dredging, stormwater management, and environmental remediation. Contractors managing site runoff, municipalities treating lagoon sludge, and agencies overseeing dredged material disposal all rely on geotextile-based containment and filtration systems to manage water and solids efficiently.

Coleman Moore's Concrete Washout Bags are available in two sizes: 0.87 cubic yards and 1.62 cubic yards. Both options are constructed from tough, flexible polypropylene and are sized to accommodate typical ready-mix truck washouts and concrete pump cleaning operations on active construction sites.

The Road Drain system by Wimco uses a 2-step filtration process that captures and contains sediment from water flowing into roadway drains. Its durable sealing gasket prevents bypass, while the wheeled, compact design makes it easy to move and service. Filters are replaceable and reusable, making it well-suited for long-term construction site dewatering and sediment control.
