Poly-Mart manufactures 500 Gallon Water Storage Tanks made from the highest quality FDA approved polyethylene. These tanks are also BPA-Free and have built-in UV inhibitors to avoid color fading and break down from harsh sunlight. Our Water Storage Tanks are designed for above ground use and like other polyethylene holding tanks, they are not suitable for pressurized applications. This tank is 500 U.S. Gallons in capacity and is 48"D x 71"H. Our Black, Dark Green, Dark Grey & Dark Brown polyethylene 500 gallon Water Storage Tanks limit the most light penetration, which reduces growth of waterborne algae.

Like all of our Vertical Tanks, the Poly-Mart 500 Gallon Water Storage Tank is designed with 4 Dome Flats on the top of the tank and 4 Layout Flats at the base of the tank. These 8 Flats 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. If you would like to order your tank with additional fittings please consult with your distributor. Orders requiring additional and custom fitting placement are subject to additional fees and fitting cost. Please utilize our technical drawing (detailed information tab) to communicate where and what size fittings you would like.
