Molded - Horizontal

Horizontal tanks and horizontal leg tanks utilize a cost-efficient design, simplifying installation and saving you money. They are used for a wide variety of applications including the storage and/or transport of potable water, gray water, wine, most liquid agricultural chemicals, and many industrial chemicals. Horizontal leg tanks utilize molded legs to conveniently mount on flat surfaces without any additional support. Eliminating FRP saddles and steel cradles allows easy installation and provides significant cost reduction. Large capacity horizontal tanks, called Elliptical tanks, are also available. Fittings and accessories consist of tank skids and stands, support bands, hoop assemblies, ladders and more.
