And any way to improve it may require increasing levels of government interference, but increasing levels of government interference ≠ improvement.
I know it sounds obvious when put that way, but too many people fall into the trap of thinking that because something must be done, anything must be done. And, that because something was done, it was a good thing. Which is seldom true, unfortunately.

Agreed but I think increasing interference in the "wrong"(as in not most effective place I.E. watering lawns) place will put pressure on them to also put pressure on the right places so the people under the first problem don't feel like they are over contributing.
That said I've not read any studies on this so really I'm just guessing blind here.
Does it guarantee improvements? Nope, but it does get more people on the side of conservation.
Any way to improve it would require increasing levels of government interference. Clearly people(industry included) aren't willing to self regulate their water usage or they would already be doing so.
