100 Gallon Water Storage Tank – Poly-Mart manufactures a 100 Gallon Water Storage Tank made from the highest quality FDA-Approved, NSF-Approved, Food-Grade, BPA-Free, High Density Polyethylene (HDPE). This material features built-in UV inhibitors to avoid color fading and break down from harsh sunlight. Our 100 Gallon Water Storage Tank is designed for above ground use and like other polyethylene holding tanks, they are not suitable in applications where the tank inself would be under pressure. This tank 30”Diameter x 42”High Plastic Water Tank has a total capacity of 110 Gallons when completely full.

Like all of our Vertical Tanks, the Poly-Mart 100 Gallon Water Storage Tank is designed with 4 molded-in Dome Flats on the top of the tank and 4 Layout Flats at the base of the tank. These 8 flat spaces set our tank design apart from others and provide flat surfaces for installation of additional Outlet/Inlet fittings, Tank Over Flow Fittings and Tank Components like Float Switches & Tank Gauges. Your Installer or Contractor will love having flexibility when needing to install additional fittings for your application.
