Porta Tank™ bolted steel, membrane-lined tanks are optimal for permanent or temporary above-ground storage. The factory-sealed and tested liners were fabricated from a tough supported thermoplastic. With capacities of 6,500 to 1.5 million gallons, the tanks seldom require a concrete foundation and are available with double liners, leak detection, floating covers, powder-coated walls and turnkey installation. - Lockport, Ill. - (815) 838-8331 - www.environeticsinc.com
