Our 500 Gallon Rainwater Harvesting Tank is a great size to store your collected rainwater in almost any residential back yard! We designed our 500 Gallon Rainwater Harvesting Tank sit below a standard 6′ foot residential fence lines, which is required by some Home Owners Association’s.

Like all of our Vertical Storage Tanks, the Poly-Mart 500 Gallon Rainwater Harvesting 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 surfaces set our tank design apart from others and allow you to daisy chain tanks together or provide flat surfaces for installation of additional outlet/inlet fittings, Tank Over Flow Fittings, Float Switches, Tank Gauges and other Rainwater Harvesting Accessories. Your installer or contractor will love having flexibility when needing to install additional fittings where you need them most in your application. Poly-Mart 500 Gallon Rainwater Harvesting Tank comes with a 16″ Stainless Steel Mesh Tank Screen installed on the top of the tank. The 16″ Tank Screen (or sometimes referred to as a Strainer Basket) is the rainwater entry point of the tank. It’s primary job is to keep mosquitoes out of the rainwater tank and allows a large entry point of pre-filtered rainwater to enter the tank. Large debris like sticks and leaves should be filtered out prior to reaching the Strainer Basket by using a Rain Head and/or a First Flush Diverter. There is also a stainless steel mesh screened overflow assembly, outlet bulkhead fitting and a 3/4″ bulkhead fitting for a water hose spigot. The stainless steel mesh screened overflow assembly is designed for directing overflown water during large rain storms while doubling to keeping pests & mosquitoes out of the tank. Our 3/4″ bulkhead fitting is placed at a height that enables you to install a spigot and fit a watering can underneath for filling. Collected rainwater is technically non-potable. Do not drink collected rainwater without proper filtration.
