Landscape Water Budget Tool

To assist home builders, landscape professionals, and irrigation partners in meeting the outdoor criteria of a future WaterSense specification for new homes, EPA has developed a Landscape Water Budget Tool to help guide them through the water budget calculations of the draft specification for water-efficient, single-family new homes. The landscape water budget tool will help determine:

• The amount of water the designed landscape is allowed (budgeted) based on EPA criteria.
• How much water the designed landscape requires based on climate, plant type, and irrigation system efficiency.
• Whether the designed landscape meets the budgeted amount.

The Landscape WaterBudget Tool is in draft form at this time. EPA is inviting all interested parties to provide comments on this new tool, specifically recommendations on data sources and sources of local reference evapotranspiration.
