Texas Metal Tanks


About Texas Metal Tanks

Texas Metal Tanks began in the 1930’s in Yoakum, TX.   Now TMT is right down the road from Austin in a 5000 square foot building just north of Dripping Springs, TX. 

While manufacturing processes have been improved with newer tools and techniques, each tank retains the TMT hand made quality.  Each tank, still formed by hand, utilizes spotweld or riveted seams. 

Sustainability is a key part of the TMT vision.  Unlike a plastic tank which may spend a thousand years in a landfill when they’ve reached the end of their useful life, our metal tanks are nearly 100% recyclable. 

Tank Construction:

Texas Metal Tanks manufactures both traditional galvanized steel cisterns and stainless steel cisterns.  The galvanized steel tanks are G-90 grade 20 gauge metal made in the USA.  We do not import 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.

TMT also manufacture type 304 stainless steel cisterns.  The sidewall and bottom are 20 gauge and the top is 22 gauge.  We use stainless steel rivets in the construction process making them more durable.  The tanks utilize a FDA approved NSF 61 certified sealant on the inside.  Stainless steel tanks are actually an alloy – the addition of chromium to the steel greatly increases the corrosion resistance of the metal.  Stainless steel tanks will generally maintain the same look throughout their lifespan.  A stainless steel tank should last 50 years or more and feature a five-year warranty.

Standard Tank Dimensions and Pricing:

Note:Dimensions are eave height.  The top adds 6 – 15″ to total height, depending on size of tank.  Pricing includes one outlet.  See ordering information below.

Ordering Information

Leadtime: Three to four weeks on standard tanks.

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.  With a basket, you can spin the top so that the basket is under a downspout.  With the basket positioned correctly, secure the top in place.

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.
