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?

if our building is part of a bigger development which has a central waste water treatment plant does this count as being an onsite plant and will it count towards option 2.reducing 50% of building sewage conveyance?

Razan, I would review the LEED Minimum Program Requirements supplemental guidance document for some perspective on this question. There are cases (like with parking) where something can contribute to a credit without being in the LEED boundary. I would consider this a good possibility in your situation.

Hi Razan! We had the same case in a project. They awarded us WEc2 but not WEc3. They said that all water coming from this treatment plant (in a university campus, in which our building was located) counted as "municipally treated", not "on-site" and would qualify only to earn WEc2. Hope it helps.

Hello, I have the same question. My project is located at an industrial park and they have a Central treatment water plant outside of my LEED boundary and the water is for the all the irrigation areas in the park. Does this count for the credit?

Dario, as I mentioned earlier, please review the MPRs, especially MPR3. There is a relevant exception in MPR3, and while I don't know if it has been applied in this type of situation, it seems like it should work.

For our factory project, We DID have an exterior treatment plant, but it was on adjacent land owned by the same owner. So--between Nadia's answer and mine you can see what is allowable and not allowable for this credit. Please note: for our credit compliance, we had to show in detailed calculations that the capacity of the treatment plant was enough for all recycled water needs,AND that the INPUT to the system from our project was sufficient for the OUTPUT requirements (so it was calculated as if it was a stand-alone treatment plant).
