Just curious as to which states require licensing for irrigation. At this point Colorado does not,but I believe it would be a good idea. All that is required is to have a cross-connection license (which I do) and get a permit pulled (which most don't). Especially since the water boards/city councils are creating landscape and irrigation ordinances. Not sure how they will enforce any of the new measures (which I will talk about in my next post). What are your thoughts on licensing?
