Water Budget Tool

EPA developed the WaterSense Water Budget Tool, Version 2.0 to help builders, developers, landscape designers, irrigation professionals, and other interested parties improve water efficiency through landscape and irrigation design. Using local climate data and user entries, the tool is intended to compare estimated water use for a designed landscape and irrigation system to one using practices typical of standard new construction. The tool can be used for both residential and commercial landscapes to help the user make landscape and irrigation choices by zone to reduce water use and utility costs. This tool isn’t meant to determine irrigation scheduling—instead, local sources of real-time weather data are more appropriate for that purpose.
