In the aftermath of a disaster, such as an earthquake or a landslide, it usually takes three to four days before large toilet arrays can be delivered. Three days without proper toilets is dangerous enough to cause plenty of water-borne diseases. RElieve is a portable toilet system designed for disaster camps. Made of waxed cardboard, it is lightweight and water-resistant and packs flat. It is intended as a temporary, low-cost solution. Users simply place a plastic bag onto the seat before using the toilet; afterward, they dispose the used bag into a community collection bin.
