This article summarizes the work completed in Phase 1 of the Alliance for Water Efficiency’s (AWE) Outdoor Water Savings Research Initiative. Phase 1 was a review, analysis, and synthesis of published and pending research on outdoor water use and water savings. In particular, studies that documented water savings were reviewed. The research in Phase 1 was conducted specifically to identify the area(s) of greatest need for future research. Key findings are: • Outdoor water savings are achievable and can be significant. • Quantifying water savings from outdoor programs and measures is challenging. • Cost savings of any kind are rarely documented. • Standardized approaches and methods for measuring and evaluating outdoor water efficiency programs are needed.
