NC-v4 WEc2:Indoor water use reduction

On-site waste water treatment

In LEED 2009 there was a credit dedicated for reducing waste water or treating it on site. How does LEED V4 reward onsite treatment?

Lorne, basically this is covered through encouraging use of alternative water sources, e.g. in this credit higher points can be earned through reducing potable water use including through alternate sources.

Right. I do understand that. I was more curious if you treat the waste water and perhaps do not reuse it. For a basic example, take a lagoon or a septic tank - these were previously awarded points which are no longer from what I can see. A better example is the eOmega building in upstate NY which uses a living machine: http://www.eomega.org/omega-in-action/key-initiatives/omega-center-for-sustainable-living/eco-machine%E2%84%A2 This treats the water and then dumps it into the aquifer below. Since its not reusing this water it could not be an alternative source and thus not rewarded in any way. Let me know your thoughts.

Lorne - It looks to me like USGBC removed this credit from their scope entirely.
