More than half the water used in the home and workplace does not need to be of drinkable quality yet it comes from the same pure source as our kitchen taps. Much of the water that enters a building can be used twice before being placed into the national wastewater management system. So-called grey water from washbasins, baths and showers is pumped up to the grey-water system, where it is filtered and can be used to wash clothes, flush toilets or water the garden.

Israel is becoming a world leader in water management. Due to its population and industrial growth, scarcity and threats of having its water supply disrupted by Syria and Lebanon, Israel has been forced to become resourceful in its management of water.
 
66% of Israel is considered arid. The lack of water resources in these areas (mainly Southern Israel) has been the main inspiration for farmers to try new, innovative irrigation techniques to make the desert blossom. Probably Israel's field with the most advancements when it comes to water technology, drip irrigation is the main method used to conserve water while making sure that plants and and farming land get enough water. Drip irrigation is the most efficient method as regards water saving. Since the drippers emit the water directly to the soil adjacent to the root system, which absorbs the water immediately, evaporation to the air is minimal. This effect is especially important under the conditions prevailing in arid zones.

Recycling of nutrients by reusing water drainage in soiless cultivation appears to be the most logical solution: approximately 50% of water and fertilizer inputs are saved, because of reduced tap-water supply and improved nutrient availability to the plants. The potential pollution of the aquifer from the open irrigation system is reduced. The transition from an opened to closed irrigation system unexpectedly resulted in yield increase and higher fruit/flower quality, due to the higher fertigation control and monitoring applied in the new technology.

The expanding urban population, as well as political developments, will likely further reduce the fresh water supply for agriculture. The solution lies in the desalination of brackish water and high-level water reclamation. Multiple skills, talents and experiences are enlisted to provide integrated solutions that embrace soil, water, additives, plant and livestock varieties, equipment and structures. The results are measured in improved yields produced at lower costs, a win-win situation in a resource-stressed world. more
