As part of the October 2016 LEED addenda update (http://www.usgbc.org/articles/leed-addenda-update-october-2016), USGBC updated the Water User Reduction Guidance document to Version 9 (http://www.usgbc.org/resources/water-use-reduction-additional-guidance). While it is touted to utilize new guidance related to applying on-site alternative water sources (like campus or municipally reclaimed treated wastewater and seawater) to credit achievement (WEp1 must be achieved through project fixture and fitting efficiency measures alone), it also contains help for those using the Water Use Reduction Calculator that was part of the v06 forms release.
