Mine Tailing & Coal Ash Stability & Drainage Systems

Catastrophic tailings dam failures are disastrous and avoidable.

 Tailings deposits cause a variety of environmental problems, the worst being deadly landslides.

DeWind One-Pass Seepage Control Systems can maintain embankment stability, control water levels , seepage, and maintain water-quality at the site. 


Options for seepage control include constructing drains for seepage collection, and/or constructing seepage collection with pump back& (or treatment) systems. Sometimes seepage control systems are combined with low permeability barrier walls for additional dam stability and slope control. 


All drainage systems and barrier walls are installed under the water table without open excavation, with minimal site disturbance.
