Residential Wastewater Treatment Systems
NSF evaluates all residential wastewater treatment systems, regardless of treatment technology, in test facilities throughout the U.S., Canada and Europe.
Manufacturers may choose to get certified to various industry standards, including:
NSF/ANSI 40 for Residential Wastewater Treatment Systems
NSF/ANSI 40 provides material, design, construction and performance requirements for testing and certifying residential on-site systems.
With more than 45 years of market use and acceptance, NSF/ANSI 40 is the most recognised and required standard in the residential wastewater treatment industry.
CAN/BNQ 3680-600 for the Canadian Wastewater Market
NSF provides testing needed to comply with CAN/BNQ 3680-600, a standard based on the methodology of NSF/ANSI 40, but specific to products sold in Canada (due to its cold climate requirements).
NSF/ANSI 245 for Nitrogen Reduction
The NSF/ANSI 245 standard requires a minimum 50% reduction of total nitrogen. This rigorous standard helps wastewater treatment providers meet a growing demand for nutrient reduction in coastal areas and sensitive environments.
NSF/ANSI 46 for Wastewater Components and Devices
If you manufacture wastewater components and devices not covered by other wastewater standards, testing and certification to NSF/ANSI 46 can help provide market access for those products.
NSF/ANSI 385 for Disinfection Mechanics
This standard was created for manufacturers of disinfection devices used in treating, recycling, reusing and disposal of wastewater from residential treatment systems.
What Sets Us Apart
When you work with NSF, you can expect:
- Detailed NSF test reports: These reports demonstrate the independent validation of your system performance.
- Public listings that are easily accessible to stakeholders: Because all certified residential wastewater treatment systems are listed on NSF’s website, certification to this standard opens the wastewater market to your company and product(s).
- Use of the NSF mark: With certification comes authorised use of the NSF mark, which provides credibility and peace of mind to both regulators and end users of your products.
