150 Gallon Rainwater Harvesting Tank



Our 150 Gallon Rainwater Harvesting Tank is a great size to store your collected rainwater in ANY residential back yard! Our most popular size our of our 30″ Diameter Tanks, this tank will store 3 times the rainwater as a standard sized rain barrel and will take up the same foot print. We designed this rainwater tank to sit below residential fence lines, which is required by some Home Owners Association’s.

Rain Harvesting or Rainwater Collection is the catchment and storing of rainwater for use in a later date. There are numerous reasons for collecting rainwater. Rainwater collected from roofs of houses can make an important contribution to the general availability of water as well as household water cost savings. Whether you would like to water your plants, garden, home foundation, or have an outdoor water source for hand-washing or pressure washing, rainwater is FREE and you should collect it. If you don’t, we use energy to pump it back out of the ground! Collecting Rainwater is a self-sufficient way getting water and also provides a net positive impact on the environment. Whether your motivation is one or all of these, a Rainwater Harvesting Tank is arguably the most important component of your system!

Don’t settle for a plastic tank that requires retro-fitting in order to properly collect rainwater! Poly-Mart Rainwater Tanks are assembled specifically for helping you properly collect rainwater! Sold exclusively through Retail and Online distribution, Poly-Mart Rainwater Harvesting Tanks are available in various sizes as well as 13 different colors! Like all of our Vertical Storage Tanks, the Poly-Mart 150 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 150 Gallon Rainwater Storage Tanks come with a 16″ 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. 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.
