University of Arizona: Harvesting Rainwater for Landscape Use

In arid climates, such as the Southwestern United States, "rainfall is scarce and evapotranspiration rates are high." This type of climate often makes the practice of "water harvesting" necessary for sustaining plant life in the area. This site contains an archived publication titled "Harvesting Rainwater for Landscape Use" by Patricia H. Waterfall, an Extension Agent at the University of Arizona Cooperative. In the article, both diagrams and detailed descriptions of water harvesting systems are outlined. Water harvesting techniques are quite effective, and can often cut back on the amount of drinking water used for landscaping purposes.
