Are you interested in installing an irrigation system that uses water super efficiently? According to the EPA WaterSense website, "Micro-irrigation systems use 20 to 50 percent less water than conventional sprinkler systems." Micro-irrigation systems slowly and precisely deliver water exactly where it's needed.
The WaterSense site has a new, free guide to micro-irrigation, available here, which will help you figure out if it's right for you, and then walk you through the details.
Happy Water-Wise Gardening!
