Poly tanks may last up to twenty years. Those designed for drinking water and similar items are potable poly tanks while those carrying chemicals, fertilizers and other fluids are non-potable poly tanks.
Poly tanks have myriad shapes, sizes and applications. The most common vertical poly tank stores everything from chemicals, fertilizers and fuels to foods, beverages and pharmaceutical products. In another vein, the recreational poly tank is custom-shaped for water and waste storage in boats and other recreational vehicles.
