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.”

Robert S.

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.”

NSF International Certification for Bolted Tanks

NSF Storage Tanks

Superior Tank Company is proud to announce we have recently earned NSF International Certification for our bolted steel tanks over 14,309 gallons. NSF/ANSI 61 and 372 Certification of our bolted tanks demonstrates compliance to the internationally recognized health effects standard for drinking water system components. NSF International led the development of the American National Standards for all materials and products coming into contact with drinking water and NSF/ANSI 61 & 372 sets health effects criteria for many water system products, components and materials. For example, NSF International standards are used to verify the safety and performance of water treatment and plumbing components and to ensure these products do not leach harmful levels of contaminants into drinking water.

In order for the entire bolted tank to earn NSF/ANSI 61 & 372 certification, our bolted tanks were subjected to rigorous testing and evaluation to verify they met the stringent requirements for storage of drinking water. Various elements of the bolted tanks were analyzed including our epoxy powder coating, encapsulated tank hardware, EPDM gasket material. In order to earn certification, the performance of the product must meet rigid durability standards and our factory powder coating and tank components exceeded standards. In addition, our bolted steel storage tanks were tested and found to meet to the requirements for “lead free” product listing. The laboratory staff even noted how robust our powder coating was and how well it held up to testing. In addition, NSF International audited our bolted tank manufacturing facility in California to verify compliance to the requirements. Not only did our process meet the certification requirements, but the inspector commented how organized our manufacturing facility was.

When NSF Certification of the entire tank is not required, Superior Tank also now offers an NSF Certified Off White epoxy powder coating. The new color provides the same durability and performance as our Tank Tan epoxy powder coating with NSF Certification but increases the contrast between the water and the tank interior making it easier to see the tank bottom and identify potential water clarity issues.
