First National Standard for Graywater Systems
NSF International has published the first American National Standard for water reuse systems. NSF/ANSI 350, Onsite Residential and Commercial Reuse Treatment Systems, will help ensure that systems designed to treat wastewater for non-potable onsite reuse meet water-quality requirements for the reduction of chemical and microbiological contaminants.
The standard applies to any system capable of meeting the requirements without limitations on system design or treatment capacity. The standard comes in part as a response to an awareness of the inefficiencies of aging centralized wastewater treatment systems, according to NSF.
