Permatank® provides secondary containment and corrosion resistance of FRP and the strength, flexibility and fuel compatibility of steel.
Licensed by the Steel Tank Institute (STI), Clawson Tank Company produces the Permatank® using the same leading-edge technology and state-of-the-art manufacturing expertise that have made Clawson a recognized leader in meeting the ever-changing needs of the petroleum industry since 1946.
Permatank’s® advanced design and proven technology make it efficient and economical. Permatank® is installation friendly. Its flat-head shape reduces excavation space and back fill costs on the average UST by more than 19%. Permatank’s® strength resists buckling in unstable, high ground water soils.

Built for convenience, the PT Sump riser is easy to open, simple to install and features a water-tight lid design.
