Sievers Poly Tanks manufactures and distributes plastic storage tanks. They offer tanks in various sizes, types, and shapes, including water storage tanks, rainwater harvesting tanks, DEF tanks, cone bottom tanks, chemical tanks, double wall tanks, vertical tanks, horizontal tanks, elevated tanks, oilfield treater tanks, firefighting tanks, secondary containment tanks, bladder tanks, open top tanks, and rectangular tanks.

They are lighter than tanks made from other materials and are less likely to react to the stored liquid. The company also specializes in Diesel Exhaust Fluid (DEF) tanks for bulk storage or dispensing up to 20,000 gallons and works with wholesale fuel distributors to custom mold, design, and modify production tanks for DEF, oil, and other fuel applications.
