If giant rain barrels aren’t aesthetically pleasing or you lack the room for installation, you may want to consider the Eco Sac; a flexible rainwater bladder storage system that hides away under decks or floors. Each sac is manufactured using “industrial strength fabric sealed by high frequency welding.”

According to the site, the eco sac is better than your average rain barrel because a.) it captures water faster than rigid tanks, b.) you can use multiple bladders which all fill at the same rate and at the same time c.) it is guaranteed not to leak and d.) it is algae resistant and the water stored is potable.

Pretty cool idea for those with limited space to capture rainfall. There are 54 different sizes to choose from, ranging from 2,200 liters to 8,600 liters. Apparently, you can join multiple sacs together to get up to 50,000 liters or more water storage.

Much like the portable grey water recycler we wrote about earlier this week, this product is currently only available in Australia. Something tells me however — with the water woes currently affecting parts of the U.S. — that we’ll be seeing more of these stateside shortly.
