It is amazing how necessity is the other of invention. Singapore has no freshwater supply. They buy water from Malaysia under long-term contract. They pioneered a bottled water - for drinking, yes -- made from recycled wastewater/sewage (which I still have the ick factor for).

This is interesting news for desalination to be that cheap. Would be interesting to understand how they do it, though that's out of scope for this TF.

Hi Marn Yee and Sue,

According to this reference: http://www.edie.net/news/news_story.asp?id=11402&channel=0 a large reverse-osmosis desalination plant in Singapore is producing fresh water for a price that equates to 0.2 cents per gallon. That's about equal to the current retail price of water in Mtn. View.

The volume is 36 million gallons per day, which is about 3x Mountain View's current average usage, if I recall correctly. It provides enough water to meet the needs of 459,000 people (10% of Singapore's population).

No action required, but I was quite surprised by this price point and thought you might be too.

Cheers,
Bruce
