Water Storage Tanks

Rainstorm Solutions is proud to be the dealer in North Carolina and South Carolina for CorGal Water Storage Tanks, The nations leading provider of corrugated galvanized steel Water Storage Tanks.

CorGal galvanized steel tanks are used for water or liquid storage. CorGal tanks are constructed of Scafco corrugated, galvanized, punched and rolled steel wall sheets that are bolted together at a project site. Most CorGal tanks are round structures but special shapes can also be produced. CorGal tanks are very adaptable and range from 6’ to 105’ in diameter.


CorGal liquid storage tanks generally are fitted with pre-liners and flexible membrane liners on the inside of the tanks for water containment. The CorGal tank does not have a bottom structure. Most CorGal corrugated tanks are constructed on a concrete foundation.

For the few applications where a liner is not suitable then a CorGal tank can be constructed with double punched and gasketed wall sheets that are bolted together. A concrete floor is then poured inside the tank to complete the water seal.

CorGal tanks are installed by trained CorGal Water Storage Tank Assemblers working under the network of CorGal Dealers or which Rainstorm Solutions is for North and South Carolina.

CorGal corrugated galvanized steel tanks are used for both permanent and temporary liquid storage. CorGal tanks may be disassembled and relocated if necessary.
