I only deal with Superior

“I DO NOT deal with any other bolted tank company, period. I deal only with Superior because of Huel, and he makes sure I get the best product that Superior has to offer and Huel stands behind what he puts his name on.”

The quality of the build was excellent

“The tank you built for us in 2002, has absolutely no wear on the Powder Coating or any other feature of the tank. The quality of the build was excellent, we automatically go to Superior for our tank needs as it is a known quantity.”

A Historic Moment

“Today  water began flowing to our customers. A bit of clean-up, replace the Brown’s gate, and we will be finished. One bit of history I remember tells me that this is the first project of this magnitude since the Empire State Building to finish ahead of schedule and (slightly) below budget. Thank you for your support.”
