Ryan,
Which of the three course you played don't use recycled water.
I think the infrastructure would surprise you. I left AZ 9 years ago, so they've done more since then, but in Tucson they had pipe from the waste water plant to all the courses within the city as well as up to Dove Mountain. Even the older "grandfathered" courses like Skylinks and the CC were converting to waste water at $490/acre foot at that time.
In PHX, all of the courses within the city are on reclaimed with the exception of a few older courses like Orange Tree and maybe a few of the really old CC. There was waste water being used at Desert Mountain, to give you an idea of how far the web stretches.
Get out into the rural areas and there is a lot less reclaimed used, but a lot less golf as well. So, unless you talking about playing courses out in the country most of the courses you've played in AZ are on the reclaimed water web, which tells me they are way ahead of you with your desire to restrict the use of potable water.
This is the most difficult time of year in the desert. Your trying to heal from transition, it's brutally hot, and you've had no help from mother nature for many, many months. Once the monsoon season hits and you get a few flushing rains it gets easier.
Although the reclaimed water is treated, it still high in bicarbs and sodium. When you irrigate for months in high heat with no flushing rains you build up the salts in the soil and it takes more water to dilute them. Its a downward cycle that only starts over when a flushing rain, like a summer monsoon t-storm, resets the soil. Having said all that, I have no idea why those course where so wet. They sounded pretty bad, although the roped off areas are usually a result of an irrigation failure, (break, stuck head...etc) rather then simply running the heads until you make a lake.
So, did I answer your question? If so, please answer mine. Are you a conservationist here in the US and in China? Are you using any recycled water with all those courses your building? What process are you using over there to reduce inputs. If I were to act like you and just fire away, I'd have to say it sure looks like you guys like to go over the top with your approach, and I don't see how that matches your attitude expressed here.
