Portadam’s above-ground water storage impoundment system is utilized as an option for central frack water storage where in-ground impoundments or frack tanks are either not permitted or not viable. The flexible framing arrangement of the Portadam above ground impoundment system allows for easy assembly, breakdown and re-assembly when used for multiple fracking sites. This time proven and economical water impoundment (fracking) system permits installation in almost any configuration with provision for under-floor piping to accommodate inflow /outflow requirements. The Portadam system can be constructed to handle any capacity up to 10 feet high (factoring in the 2′ freeboard requirement).
