Double Wall Tanks, also known as secondary containment are provided  to provide additional containment and protection for aggressive or expensive chemistry. The Primary vessel and a Secondary containment vessel are available as a single structure, available in fiberglass and polyethylene.

Secondary containment or dual wall tanks are back up systems, in case the primary tank would potentially fail for any reason.

Acids, caustics and other chemical compounds may stored in our 1.9 specific gravity ASTM rotationally molded double wall polyethylene tanks. Fiberglass is available in isophathalic and vinyl ester resins.

A fiberglass double wall tank appears to be the same as any other FRP vessel, however the secondary containment is intrinsic to its fabrication.

The following sequence of pictures are of a double wall polyethylene tank, with various process connections and details.

The complete vessel is to the left with ladder and tie down system. The second picture shows the Primary tank in the foreground and secondary containment on the right, also in tDouble wall plastic snyder tankhe back ground of picture on left.

tank on left is secondary containment tank,  tank on right is the primary    

The tank top extends over the secondary which prevents rain from entering the secondary containment.

These details show how a bottom sidewall process connection connects through the primary and secondary tank walls.
