The intent of this specification is to reduce indoor and outdoor water usage in new residential homes, thereby lowering consumers’ utility bills and encouraging water and wastewater infrastructure savings. EPA’s goal is that WaterSense labeled new homes will use approximately 20 percent less water than a typical new home by using a combination of prescriptive and performance-based approaches identified in this specification.
