Tank Connection ground reservoirs are available in both bolted and welded tank construction. Our RTP (rolled, tapered panel) bolted tank construction is the leading steel tank design in water storage applications. Once you combine RTP construction with LIQ Fusion 8000 FBE™ coating system, you have the BEST steel water tank containment system available in the world. It is commonly specified around the globe for municipal and potable water storage applications. Unlike glass coated tanks that utilize an erector’s set of web stiffeners, Tank Connection designs bolted steel water tanks without cheap web stiffeners. We use proper plate thickness, the same as our field-weld tank construction.
