Money down the drain?

Over the space of many years I have been highly critical of government for never having adequate backups or reserve capacity. Time and time again mishaps occur and we find out that govt has no backup. One part fails (or there is a fire on one part) on the Hornsby to Gosford railway and there is no backup. Hospital loses power - no backup. A few train drivers get sick - no backup. Roads at full capacity - no backup. Etc, etc.
One of the most important things that govt provides for us here in Sydney is water. It all comes from one or two dams and there is no backup supply. Finally govt has wisely decided a backup is required and has ordered one. Now, our govt is grossly incompetent and no doubt will get this wrong in many ways and spend far too much money. I don't doubt that. However they do deserve credit for finally giving us a backup supply of a vital service.

Some people however are not happy:
So much money down the drain
Water plant branded a bungle

This is a rare occasion when I agree with a politician:
$2 a week guarantees water supply
