(Scroll down for video) Consumers are now able to build a customized shower, which saves a large amount of water and energy by recycling.
A team of designers in Finland, has built a kit called the Showerloop, which cleans the used water and pumps it back to the shower head.
It works by sending water through five filters. The first screens out large chunks of matter, such as hair. The water is then pumped to a mesh filter.
It then trickles through a layer of sand to eliminate the last few remaining particles.
A carbon layer purifies the water, removing odors and chemicals, and a final burst of ultraviolet light kills bacteria and sterilizes the water.
Because everything happens quickly, the water does not have much chance to cool off, saving energy. After each shower, the filters can be programmed to automatically clean themselves.
The used water can then be sent to the toilet or dishwasher.
The designers report a 90 percent reduction in water consumption, and around 80 percent less energy usage.
