This 103-inch Dome Top for Water Storage Cisterns manufactured by Hydro Composites is designed for potable water and other applications. These tanks are fabricated using contact molds built in-house by our skilled staff. We use FDA approved resins and ASTM end caps for all of our storage tanks. Thickness, color, and bottom shape can be altered depending on the application for the tank. A flat bottom and domed top are standard on most storage tanks. Threaded fittings or flanges can be placed anywhere on the tank that your application requires. Manways are available for larger diameter tanks if required. If your application requires a size we do not currently manufacture, we can make a mold and produce tanks to your specifications. We have the ability to put your concept into CAD to ensure the design meets your satisfaction prior to construction. Custom features like pipe fittings/ flanges, insulated walls and bottoms, baffles, screens, and external reinforcement are available upon request. Storage tanks can be manufactured for vertical or horizontal applications. Hydro Composites manufactures all tanks using premium FDA approvable iso-resins, gel coat, and glass materials.
