Licensed Certification Providers

Organizations that commit to hire or contract with water-efficiency inspectors can partner with WaterSense. Licensed certification providers are also approved to train inspectors, oversee new home inspections, and issue certification decisions for inspected homes in the United States in accordance with the WaterSense New Home Certification System. The certification provider must signify such commitment by signing a licensing agreement and a WaterSense partnership agreement with EPA and must be approved by a program administrator.

In order to join WaterSense, a quality assurance designee from the organization's staff must attend a certification provider training session conducted either by EPA or a WaterSense new homes program administrator. Contact a WaterSense new homes program administrator to find out about the next training opportunity. The organization is eligible to become a partner once it has documentation of program administrator approval.

Promotional Partners

Promotional partners assist EPA in educating others about the value of water, water efficiency, and the WaterSense brand. Organizations are prohibited from earning a profit from the use of WaterSense program tools and materials. To be eligible to become WaterSense partners, organizations must educate or work with consumers or organizations located in the United States and Canada.

These partners fall into one or more of the following organization types:

  • Nonprofit Organizations: Examples include environmental organizations, nonprofit certifying organizations, and consumer advocacy groups.
  • Professional and Trade Associations: Associations whose members are eligible to join as a WaterSense partner can also join as promotional partners. For example, because water utilities are eligible for partnership, the American Water Works Association, whose membership includes several thousand utilities, is also eligible. Home builder associations and trade associations that promote water-efficient products and practices to commercial and institutional facilities, such as green hotel or restaurant networks, are also eligible to partner with WaterSense.
  • Utilities/Water Districts/Government Agencies: Environmental departments, municipal programs, water agencies, water districts, wholesalers, public utilities, private utilities, wastewater treatment facilities, water boards, and public utility commissions of federal, state, provincial, and local agencies.

  • Sell, market, and encourage the use of WaterSense labeled products to customers in the United States or Canada within 12 months of execution of a partnership agreement.
