Our 100 Gallon Rainwater Harvesting Tank is a great size to store your collected rainwater in ANY residential back yard! This tank will store twice the rainwater as a standard sized rain barrel and will take up virtually the same foot print. This 100 Gallon Rainwater Tank is small enough to hide behind bushes or a small privacy fence, which is required by some Home Owners Association’s. 

The 100 Gallon Poly-Mart Rainwater Harvesting Tanks are assembled specifically for helping you properly collect rainwater! Built to last multiple decades in the full sun, the Poly-Mart 100 Gallon Rainwater Storage Tanks come equipped with a 12″ Stainless Steel Mesh Tank Screen installed on the top of the tank. The 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. Many plumb this overflow with pvc pipe to better direct the flow of the overflown water. The 3/4″ bulkhead fitting is placed at a height that enables you to install the included water hose spigot and fit a watering can underneath for filling. Collected rainwater is technically non-potable. Do not drink collected rainwater without proper filtration.
