NSF Int’l. Publishes First U.S. National Standard for Water Reuse

NSF Int’l. has published the first American national standard for onsite water reuse treatment systems.

NSF/ANSI 350: Onsite Residential and Commercial Reuse Treatment Systems establishes criteria to improve awareness and acceptance of water reuse technologies that reduce impacts on the environment, municipal water and wastewater treatment facilities, and energy costs.

Certifying a water reuse system to NSF/ANSI 350 also satisfies requirements for leading green building programs. The U.S. Green Building Council has included reference to NSF/ANSI 350 in their LEED Building Design & Construction 2012 Draft Standard.

NSF/ANSI 350 establishes materials, design and construction, and performance requirements for onsite residential and commercial water reuse treatment systems and sets water quality requirements for the reduction of chemical and microbiological contaminants for non-potable water use. Treated wastewater can be used for restricted indoor water use, such as toilet and urinal flushing, and outdoor unrestricted water use, such as lawn irrigation.

Shawnee, Kansas-based Bio-Microbics is the first company to earn NSF/ANSI 350 certification.

NSF Int’l. is an independent global organization based in Ann Arbor, Mich., which certifies products and writes public health standards for food, water and consumer goods.
