What caught my attention was this tidbit:
Canberrans pay the most for their water, slugged an average of $879 a year, while Melburnians pay the least at $539 annually.That's $630 and $386 using exchange rates and $668 and $409 using PPP rates [PDF] (Australia is 6 percent more expensive than the US.)
Compare these numbers to the average water bills in:single comparison of rates?]
Anyway, you get the point -- Aussies are paying more -- sometimes more than DOUBLE -- what Californians are paying for water. Oh, and they use 13 percent the water that Sacramento residents use: 140 liters/capita/day vs. 1,060 LCD (280 gal/cap/day).
Bottom Line: Want people to use less water? Raise prices!
