I think a system similar to this could work.
The guy in the video had a big pump powered by a generator that supplied the sprinklers with water from a swimming pool. The sprinklers were on tripods, so the water started from 3 feet up. It wasn't clear what the sprinklers were aimed at. I think he also had sprinklers on his roof. He had some kind of fire retardant that he mixed into the water in his hot tub and then used a pump to spray it on one side of his house. He left the generators running the pump and the sprinklers on when he evacuated. Based on this level of preparation, I suspect he cleared brush from around his property, too.
The article was in the SF Chronicle and was fairly detailed regarding the precautions he took. I read the article on my news aggregator, so I can't link to it.
