Very few homes in Arizona actually have this type of irrigation. It's usually found in older neighborhoods and neighborhoods zoned for agricultural use. My sister, who is an expert on all things garden/desert/plants blogged about flood irrigation here and explained that the water sinks deeply into the soil which makes for deep roots for both grass and trees. It also helps to flush out salts that accumulate in the soil.

Snow melt and rain water is accumulated throughout the year in a system of reservoirs and canals. One of these canals runs right behind our backyard. We sign up to irrigate through our local utility company. We are allowed up to 3 hours of constant flood irrigation but we usually sign up for just an hour and a half to two hours. The utility company then sends out a schedule with our irrigation time (which lately has been in the middle of the night!). When it's our time, I drive to the end of the street to open the flood gates and turn on the valve that you can see above to get the water flowing.

My dog Sodapop goes crazy over the irrigation. As soon as she sees the water flowing, she runs up to the valve and lays right next to it. The boys love it too. They think it's a blast to take a pair of my flip flops and have "boat" races. I love the irrigation because it brings a ton of fun critters to the backyard - ducks, snakes, toads, and all kinds of cool shore birds.
Today is irrigation day and we are fortunate that it wasn't scheduled for the middle of the night. It is scheduled for late afternoon which is the hottest time of day. The boys are stoked!
We've been irrigating this way for over a year now and I still think it's kind of bizarre (although we have the happiest fruit trees ever). Almost as bizarre (but not as scary) as the scorpions out here - which I'll never get used to. But that's an entirely different post.
