Water Reuse Systems Certification

NSF/ANSI 350 establishes clear, rigid and realistic guidelines for testing the efficacy of onsite greywater and wastewater reuse treatment systems.

This groundbreaking standard provides comprehensive requirements for evaluating water reuse technologies and is referenced in the International Plumbing Code (IPC) and the Uniform Plumbing Code (UPC), and is required in many U.S. states.

Even in places where this standard is not a regulatory requirement, testing and certification provides manufacturers with important product data and provides a competitive advantage in the marketplace.

When you work with NSF, you can expect:

• Detailed NSF test reports: These reports demonstrate the independent validation of your system’s performance.
• Public listings that are easily accessible to stakeholders: Because all certified water reuse systems are listed on NSF’s website, certification to this standard also opens the water reuse market to your company and product(s).
• Use of the NSF mark: With certification comes authorized use of the NSF mark, which provides credibility and peace of mind to both regulators and end users of your products.
