Rainwater harvesting tanks include all the fittings needed to collect the rain! Our rain harvesting tanks are available in various sizes as well as the eleven different colors shown above. Rain Harvesting Tanks come with a 12″ or 16" removable stainless steel strainer basket installed on the top of the tank. The strainer basket is the entry point of the tank and keeps large debris like sticks and leaves from getting into the rainwater tank. Each tank includes a lid for closing off the intake as needed.

There is also a stainless steel screened overflow assembly, outlet bulkhead fitting and a 3/4″ bulkhead fitting for a water hose spigot. The stainless steel screened overflow assembly is designed for directing overflow water during heavy rains while keeping pests & mosquitoes out of the tank. Our 3/4″ bulkhead fitting is placed at a height that enables you to install the 3/4" quarter-turn ball valve and fit a watering can underneath for filling. Tanks up to 250 gallons can also be placed on stands (see Stands section of store) and the spigot installed at the lowest point.

Tanks feature a molded-in SunShield® Layer of food-grade black polyethylene to eliminate UV light penetration from the sun. If UV Light can’t enter your tank, algae can’t grow. This inner layer is made from the same virgin food-grade material as the outer layer of the tank, but with the added benefit of being compounded for complete sunlight protection. These two layers are seamless and are molded together at the same time, making the inner and outer layer one complete seamless wall. Testing from Texas A&M University proves these tanks measure Zero UV light intensity when placed in the full sun, even in the lightest colored tanks. Ever wondered why plastic rainwater storage tanks are mainly sold in Black & Dark Green colors? Those colors are naturally dark so they typically let in less light than other colors. With the SunShield® technology, color is no longer an obstacle! Get a tank color that matches your home or surroundings without worrying about algae growth. Testing proves our new Arctic White color w/ SunShield® will keep your stored water up to 14 degrees cooler in comparison to your standard colored dark green plastic tank on the market as the Arctic White color reflects light! In hot climates, this is important for controlling evaporation and allows the water pumped indoors in Summer months to be a little cooler! Featuring an industry leading 10-Year Manufacturer’s Warranty, these tanks are built to last.
