What's in a WaterSense Labeled Home?

WaterSense labeled homes must be at least 30 percent more water-efficient than typical new construction. Under the Homes Certification System, they are verified and certified to meet EPA’s Mandatory Checklist and achieve EPA’s water efficiency criteria demonstrating that the home will use at least 30% less water than a typical home. Each Home Certification Organization (HCO) uses its own WaterSense Approved Certification Method (WACM) to measure this. When paired with a mandatory checklist, the requirements of the WACM ensure that a WaterSense labeled home is both water-efficient, and high-performing.  Some of the features EPA evaluates when approving a WACM include:
