In July 2007, the public utility branch of the Singapore government reported the world’s lowest cost to desalinate part of its water supply at US53 cents per cubic meter.

They’ve replaced the conventional 8 inch process pipe with a new 16 inch reverse osmosis system. Singapore imports more than half it’s water under expiring contracts from Malaysia and is looking toward water independence.

Does this new cost factor reflect your impressive challenge to examine desalination?

I call your work “The Tehachapi Calculation”!! :-O
