WaterSense Philosophy

WaterSense has adopted an overarching program philosophy, or set of principles, that guides EPA in selecting products for evaluation, developing product specifications, and determining label use, partner status, leader recognition, and marketing efforts.

In order to be considered for a label, products must:

• Perform as well or better than their less efficient counterparts.
• Be about 20 percent more water-efficient than average products in that category.
• Realize water savings on a national level.
• Provide measurable results.
• Achieve water efficiency through several technology options.
• Be effectively differentiated by the WaterSense label.
• Be independently certified.
