I've heard that just as big as their desalination efforts are their water reuse efforts. All that sewage we work so hard to get rid of? Turns out that's still fresh water. Sort of. It's just got some other stuff in it is all.



Israel recycles 86% of water from the sewers compared to the second most efficient recovery in the world is Spain at 19%.


Those numbers are only for percentage of treated sewage used for irrigation, not percentage of total reclaimed water from sewage. To be fair, Israel doesn't practice potable reuse at all, compared to Singapore, Windhoek in Namibia, GWRS in Orange County, or Big Spring in Texas(direct potable reuse).


That is the 2nd most interesting point i want to hear more about. And yet the article does not go into any details.


Everything you wanted to know and VERY interesting :)

tldr; water was used as an excuse by the British to limit immigration to Israel, so from the earliest onset of the formation of Israel, Israel has been trying to tackle the problem of water use inefficiency.


LA has a big water reuse program.

I guess in many areas it is less urgent so it doesn't get done.


Orange County's water reuse system is far bigger: http://www.ocwd.com/what-we-do/water-reuse/

The Groundwater Replenishment System (GWRS) is the world's largest system for indirect potable reuse. The system takes highly treated wastewater that would have previously been discharged into the Pacific Ocean and purifies it using a three-step advanced treatment process.
