Onsite Residential and Commercial Water Reuse Systems

Innovative product designers and manufacturers have begun developing technologies to treat and reuse water while keeping it onsite. This type of decentralized treatment and reuse offers a solution that is sustainable, efficient and highly practical.

But with any new technology or process comes uncertainty and skepticism. With water reuse, improper treatment of the reclaimed water can create public health issues. To help address questions about these systems, NSF/ANSI Standard 350: Onsite Residential and Commercial Water Reuse Treatment Systems was developed. This standard sets clear, rigid, yet realistic guidelines for water reuse treatment systems. With a key focus on public health and appropriate water quality criteria for reuse applications, this is the first standard of its type for comprehensive evaluation of water reuse technologies.

NSF verifies that all design and performance requirements of the standard have been met, and confirms through testing that effluent reuse water meets stringent quality criteria for designated uses.
