We have a group certification project which includes two office towers and a large piece of landscape area. We planned to have rainwater harvesting system outside the LEED project boundary where also belongs to our development. The system caters non-potable water for irrigation of the whole site. Would such system be accepted as providing non-potable water for irrigation under WE C1 even the system is located outside the Group Cert LEED boundary?
Thanks~

A nonpotable water source used for credit compliance does not have to originate within the LEED boundary.

Hi Tristan,
Can you give us a reference to what you quoted above that we can cite in our LEED comment response. We have a similar issue where we are collecting rainwater from an adjacent parking garage (outside leed boundary) to use within our leed boundary for irrigation & flush fixture demands. Specifically I'm asking in reference for credit WEc2, but I assume the same rules apply.
thanks!

Shannon, I'm not quoting anything—it just makes innate sense to me. LEED allows purple pipe systems, for example, which originate offsite. Promoting demand for reused nonpotable water is something it encourages.
