FAQs about WEc2 :

The credit language says the Option 2 involves a reduction in wastewater. Does that mean that all water, including process water, should be included?

Can project teams include reclaimed water systems that are planned and funded, but not completed?

NC-2009 WEc2:Innovative Wastewater Technologies

Treated wastewater definition.

Hi, working on an office building project, we r pursuing this credit through option 2 : "Treat 50% of wastewater on-site...etc." Through the design Preliminary Review we received a comment stating that the wastewater should be generated from the flush fixtures not the lavatories as we did in the design. My question is : Does anyone have an information (a definition in the reference guide) that state that the wastewater is water generated from flush fixtures only? because we have an intention to send a clarification stating that nothing in the guide state this. Please advise.

Water from lavatories and showers is considered wastewater by code definition. It is unlikely, however, in an office building that the lav and shower waste would add up to 50% of the total wastewater. Here is a sentence from the ref guide "Graywater systems reuse the wastewater collected from sinks, showers, and other sources for flushing toilets..."
