“Our mission is to provide the best quality galvanized steel tanks along with friendly and helpful customer service.”

A-1 Tank LLC has been manufacturing galvanized steel water storage tanks since 1984.

We manufacture, sell, and deliver both above ground and underground steel water storage tanks all over California.

A-1 Tank LLC provides custom manufactured tanks for private and public water storage needs such as emergency fire suppression, crop irrigation, or other needs for bulk water storage.  Our customers include homeowners, ranches, farms, vineyards and public agencies such as Cal Fire.

We can deliver to hard-to-reach places with our 4X4 delivery trucks and set the tank precisely on your level area.

Our tanks can be ordered with an optional water level gauge, custom colors, interior epoxy coating, and we can also provide gravel rings for setting the tank on.

A-1 Tank LLC also manufactures heavy gauge steel tanks that can be buried and out of sight.  Contact us for a custom quote.
