Doug,
Just about every golf course built in the last few years in AZ, near PHX or Tucson, is irrigated with reclaimed water. Some still use Colorado River water, but very few use groundwater.
In AZ it's the law that you must use reclaimed if it is available, and since it's also a revenue generator, it's usually made available, and using reclaimed is often a big part of the approval process.
Now, the tribal courses are not required to use reclaimed, although I think some do use it.
Both Phx and Tucson have well designed reclaimed delivery systems that have worked well to assure that almost all golf courses in the metropolitan areas use reclaimed.
I know Las Vegas has made a large push toward the use of reclaimed, but I don’t know the particulars.
Palm Springs (Coachella Valley) has talked about it for years, but little has been done there in terms of action.
It’s really quite interesting to compare perception with reality. California likes to market itself as progressive and “green”, yet it is far behind the curve in regards to water conservation to a State like AZ, which implemented water conservation laws in the late 80’s.
Along the same lines, Oregon, which again likes to sell itself as “green” has pesticide laws that are less restrictive then a state like TX where the national perception is everything goes. Things aren’t always as they seem.
