Here in California, where water is more scarce and expensive, we have been slowly converting to a lower water use landscape and drip irrigation. Mind you, I'm talking about a 1/6th of an acre lot with a 2300 Sq. Ft. two story house sitting on it, so there was never much grass to mow in any event. But when we had mostly grass, my water bill would approach $150.00 a month during the summer. We typically have a 7 month dry spell where we receive no measurable rainfall. My wife and I built a rock lined dry creek down on side of the house and across the front of the house. There are a couple of Japanese Maples and small asian junipers, azaleas and some other grasses and ground cover. Gets 5 minutes of drip irrigation every other day.
