Product & Program Specifications

Products bearing the WaterSense label are generally 20 percent more water-efficient than similar products in the marketplace. The WaterSense label will help you identify high-performance, water-efficient products and professional certification programs that embrace and encourage the use of water-efficient design. EPA issues specifications that set out the requirements that products and programs must meet to earn the WaterSense label:

• Draft Specifications Under Development:
  • High-Efficiency Showerheads
  • Weather- or Sensor-Based Irrigation Control Technologies
    
• Draft Specifications:
• High-Efficiency Flushing Urinals
• Water-Efficient Single-Family New Homes
  
• Final Specifications:
  • Certification Programs for Irrigation Professionals
  • High-Efficiency Lavatory Faucets
  • High-Efficiency Toilets

WaterSense is also reviewing many other products.

Visit the Specification Development Process page for more information on how EPA develops specifications for water-efficient products and programs.

Product Certification
WaterSense is drafting a process for accrediting licensed certifying bodies that certify products to meet WaterSense specifications. Proposed accreditation and product certification requirements are contained in the draft WaterSense certification scheme that will eventually replace the interim licensed certifying body approval process put in place in January 2007. Visit the draft WaterSense certification scheme page to learn more.
