The global water shortage is steadily intensifying due to natural population growth, pollution and unwise water usage. Water consumption in Israel is among the highest in the world. There are a few ways to lessen the water crisis, such as: pollution prevention, desalination, conservation, and recycling reclaimed water and saltwater. Using water to flush bathroom waste accounts for one-quarter of household water use. In our rain collection system, water is collected from the rooftop and channeled to a toilet cistern. In Jerusalem, the average amount of rainfall per year is approximately 500 mm. The amount of rain which falls on a 50 sqm rooftop is about 25 cubic meters. Our system uses containers of three cubic meters, enough to maintain a toilet cistern for about four months. The rain recycling project is an educational initiative in the field of sustainability, which is in line with the Garden's ecological vision.
