Plumbing Code Change Paves Way For Water Savings

By Greg Zimmerman Green

Normally, plumbing code announcements are only useful as insomnia-busters. But this one is kind of a big deal.

To allow for easier adoption of wastewater reuse and grey water recycling systems, four major codes now require that water reuse systems for flushing toilets and urinals comply with NSF/ANSI 350. The four codes requiring compliance are the 2015 International Residential Code (IRC), International Plumbing Code (IPC), Uniform Plumbing Code (UPC), and International Green Construction Code (IgCC).

Essentially, this helps unify code language for water reuse systems, and makes it easier for builders, facility managers, designers to be in compliance with water reuse systems. The goal is to speed adoption, therefore saving water, while also maintaining rigor.

According to NSF, “NSF/ANSI 350 certification ensures that water for toilet and urinal flushing (and in some codes for surface irrigation) is properly treated for use in these applications.”
