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?

Waste Water Calculation for Option 2

LEED template use the flush fixture water which calculated based on occupant usage. But our plumbing design is based on fixture unit which includes both flush and flow fixture into the WWTP sizing. Our plumbing engineer comes up with the annual waste water of 19,000 kgal but the annual flush fixture water from LEED template is only 600 kgal. How can we fill in the LEED template? Actually, all waste water will be treated by the WWTP and reused on site. We should achieve LEED credit requirement, shouldn't we?

Sompoche, you should be able to earn the credit with that system, provided you meet the specific detailed credit requirements.I don't know how your plumbing engineer and the LEED template are so far off from each other. Have you looked at the differences of what they are assuming? You should fill in the LEED template based on the LEED protocols, even if that's different from your engineering figure, but I would closely look to make sure something isn't missing.
