Financial, or environmental?
There's a push for a coal-fired desalination plant in Sydney - though generally it seems it's only the politicains pushing it. The general populace feels that it's very much a wrong-hdeaded solution. (no, can't be arsed finding real numbers to back this up).
I think the govt recently reduced the incentives for households to get their own rainwater tanks, which beggars belief.
From this I can only conclude that the State Government must have close ties to companies that build coal-fired desalination plants :)
