Recycling rain water with a rainwater collection tank - allows the use of harvested rainwater for livestock water supply, washing clothing, flushing toilets, or for landscape watering. Popular use of a rain barrel to collect water has proven the value of harvesting rainwater for outdoor use as potable drinking water that can then be saved for internal consumption offsetting both cost and supply. (Rainwater should not be used for bathing, showering, kitchen or bathroom sinks unless it is potable water that can be consumed). Corrugated steel rainwater harvesting systems for rainwater recycling come in several sizes and are shipped in pieces making them freight-friendly.

Why Choose a Rainwater Collection System?

Galvanized corrugated steel tanks have been used by numerous customers for many different bulk water storage applications. Originally known for rainwater storage in farming applications, corrugated rainwater tanks are also used by large corporations, industrial facilities, island resorts and residential homeowners to store water. One of the many advantages to corrugated steel tanks is that they ship compactly and install quickly.

Other rainwater collection tanks ship whole and take up a lot of space - so you pay to ship the air inside them! The GEI Works rainwater harvesting system is compact (water tanks ship at 1% of their fully installed size). These steel rainwater collection tanks are a turn-key solution that are user-friendly and a quick install. Our teams are standing by to take your order - these kits include the tank, the liner, delivery to your location (in the lower contiguous United States), and full installation by our professional, certified installers. Shipping outside this area, including US territories and international countries, is also available. Each galvanized tank comes with a standard 20 year warranty. Call us now for more details.
