Why is it only consumers who are on water restrictions?

There is an interesting article in todays Age which points out how much water is being used/wasted by a number of institutions.

The main questions I have are -

• Why are consumers on water restrictions when industry and government aren't?
• Why, when farmers have restrictions on how much water they can pull out of a river, a factory can still do whatever it likes?
• Why is the price for water going up for consumers, but industry can still buy water very cheaply?

If anybody has a sensible answer to these questions, post it below!
