This innovative new shower can reuse the same five gallons of water for two weeks

In order to save our precious resources, technology is coming up with some pretty innovative ways to go green, and this is no less true when it comes to water. The latest innovation on the scene is a novel new shower, which promises to recover 95 to 98 percent of the water used during your daily rinse. Called the Hotaru, this portable (sometimes you gotta shower on the go!) contraption recycles water by way of a number of water reservoirs that both store and purify H2O. With just five gallons of water, the company claims, a family of three would be able to take daily five-minute showers for up to two weeks.

Displayed over the weekend in Austin’s annual SXSW conference, the Hotaru compact shower is comprised of a plastic base in which the five gallons of water are stored, a collapsible nylon tent that stands six feet tall when fully extended, and a shower pole upon which a handheld shower head is attached. Throughout your shower, the shower drain collects the water and pumps it back through its purifying filters until it’s clean enough to reuse. This design, the Japanese company says, could save 150 gallons of water across 50 showers, when compared to traditional showers.

So just how “pure” is this water that you’re reusing for weeks on end? Hotaru founder Ryo Yamada tells Gizmodo that soap, shampoo, and dirt can all be removed from the stream, though he suggests using “mild body cleaners” instead of harsher soaps in the shower. The filters, which are clearly doing a significant amount of work on a daily basis, have a lifetime of about two months, and thanks to a built-in sensor, you’ll be alerted when it’s time to get new ones.

And don’t worry — just because this shower is portable and uses recycled water doesn’t mean you’re sacrificing anything as far as pressure is concerned. Hotaru’s showers pump water at you at a pressure of an impressive 60 psi.

Currently, the company plans on bringing the Hotaru to the American market (specifically in California) in 2017, and it will retail for about $3,000. For those who can afford it, it may be a worthwhile step toward saving the planet, one shower at a time.
