The galvanized steel tanks are G-90 grade 20 gauge metal made in the USA. 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. These galvanized tanks have a 1-year warranty.

Location: These tanks may be picked up in Dripping Springs, TX. Call Rain Harvesting Supplies for lead times: Generally, 3 - 4 weeks.

Fittings:  Most tanks take three fittings - an inlet, an outlet, and an overflow. Prices above only include one bulkhead connection for an outlet. All other fittings are optional.

Inlet:  Options include 3" or 4" male PVC adapter or a basket. The PVC adapter goes in the side of the tank on the side. Connect 3" or 4" schedule 40 PVC. The basket comes in two sizes, 12" or 16". This is inserted in the top of the tank near the edge.
Overflow: Options include 3" or 4" male PVC adapter. The overflow sticks out about 2". You can leave it as is, extend it, or run pvc pipe to the ground and direct the overflow as appropriate.
Outlet: Options include 3/4", 1 1/4", or 2" PVC bulkhead connection. This watertight seal is threaded. Most tanks, 1000 gallons or less, get a 3/4" bulkhead. This allows you to screw in a 3/4" spigot. Attach a hose, and you can gravity feed the water to your garden or trees. If you are going to pressurize the water with a pump, or may do so in the future, choose an 1 1/4"  or 2" bulkhead.  You can always reduce it with a bushing.
 Pricing includes one outlet.
