We offer a 30 year structural warranty on CorGal tanks – one of the best in the industry.

Structural materials manufactured by Water Storage Tanks, Inc. are warranted to be free from defects in material and workmanship for thirty (30) years from the date of shipment of the materials.  If a defect is found by Water Storage Tanks, Inc. within the warranty period, then we will repair or replace those defective materials free of charge or refund the customer the original purchase price of the defective materials, in lieu of such repair or replacement.

For galvanized steel tanks that are wrapped in Water Storage Tanks, Inc. supplied timber staves, the timber staves are not covered under this warranty.

Liners used within our tanks carry their own separate warranties ranging from 10-20 years respectively.
