While Israel’s authorities allow almost no decentralized water systems, experts stressed that there would be a place for such structures – particularly greywater recycling mechanisms – in the country’s future, at a conference in the Negev last week.
The third Sde Boker Conference on Advanced Water Management Technologies was held at Ben-Gurion University Sde Boker campus.
On a national scale, using greywater could reduce urban water consumption by an annual 140 million cubic meters by 2050 (around 10%), as well as reduce electricity usage by 560 gigawatthours (about 0.5%) by that time, according to Gross.
Meanwhile, the country would be able to eliminate the need of one large desalination plant, reduce carbon dioxide emissions by about an annual 6 to 8 tons and save about $3 billion-$4b. in direct costs by that same year, he added.
It sounds like some *heat* and *green* might be saved when one begins to see the light.
