&gt;it&#x27;s simply useful for people to know that this level of private consumption exists.<p>Why?  How can we assume that this water is being wasted?  What if the owner has a private hydroponics system, and they sell produce to farmers markets?  It&#x27;s legal, productive, and requires a lot of water.<p>Starting a witchhunt because a wealthy person uses a lot of water in a water-scarce area misses the point entirely, because we have no idea what the water is being used for.  If there&#x27;s a legitimate use for it, and they&#x27;re able to pay, I don&#x27;t see what the problem is.<p>If you&#x27;re worried about water being legitimately wasted, work towards getting water usage regulated so we can determine which activities are wasteful, and which are not.  Then, customers would be forced to explain water-usage like this, and could be penalized if it were deemed unnecessary.
