The galvanized steel tanks are G-90 grade 20 gauge metal made in the USA. They are not made with imported foreign steel. The top is 22 gauge. After the tank is constructed, a paint/epoxy lining is applied to the interior of the tank to provide a protective barrier between the water and the metal itself. This product is FDA approved for potable (drinking) water applications and is ANSI / NSF 61 certified. Each tank is tested at the factory to ensure that it is watertight. With almost 90 years of history, these tanks have a typical lifespan of 30 – 35 years. Galvanized tanks have a one-year warranty.

These tanks can be outfitted with a 16″ stainless steel mesh tank screen installed on the top of the tank in order to create a rainwater harvesting tank. The tank screen is the rainwater entry point of the tank. It’s primary job is to keep tree debris and leaf litter from entering the tank.  In addition, it can prevent the proliferation of mosquitoes.

The tank has either a ¾”, 1¼”, or 2″ bulkhead fitting at the bottom to get water out of the tank.
