CS-v4 SSc4:Rainwater management

using Rainwater Storage Tank as LID measure

Dear all,

I am not quite sure if the approach discussed in my project team is a viable way to achieve this credit and would like to check back with you. The project intends to collect stormwater using the underground Rainwater Storage Tank, and then  the collected water will be treated to reuse for toilet and irrigation.

My question is:

Is this kind of covered, underground approach compliant with the requirements “best replicating natural site hydrology”, is this a LID measure?

Thank you so much for any suggestions, advices.

This is one of those grey areas (no pun intended). While I could certainly support capture/reuse for irrigation, the toilet flushing part is not a GI practice.

Dear Michael, Thank you very much for your quick reply. In this case, I think I should ask USGBC for confirmation.

The official word from GBCI is that reuse (for any purpose) is acceptable.
