Our 1500 Gallon Rainwater Harvesting Tank is a great size for storing collected rainwater in backyards and is very popular for rainwater harvesting systems used for irrigation. The low-profile design allows 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 at 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. These tanks are also great for commercial stormwater harvesting systems. Rainwater is great for watering plants, gardens, home foundations, or having an outdoor water source for things like 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 of getting water but 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 regular plastic tank that requires retro-fitting in order to properly collect rainwater! A Poly-Mart 1500 Gallon Rainwater Tank comes 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 1500 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 1500 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. Also included is 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 events 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. This is a highly sought after Rainwater Harvesting Tank as it’s low profile design allows this tank to be hidden behind your standard residential fence or the majority of privacy walls.

Collected rainwater is technically non-potable. Do not drink collected rainwater without proper filtration. Please contact your distributor for proper filtration methods.
