Hello Everyone!
I am working in a project, which includes the following types of surfaces:
-Impervious roof areas
-Garden areas
-Impervious vehicle circulation areas
-Parking area with green pavement
We are analyzing the following actions to manage the rainwater in the project site:
-Stormwater tank: it will be provided a stormwater tank, for capture rainwater from roofs and reuse it in flux fixtures (toilets and urinals) and in irrigation. But only a part of the roofs will be connected to the stormwater tank.
-Green pavement: the parking area will be implemented with green pavement, in order to promote the natural infiltration.
-Impervious vehicle circulation areas and roofs (roof surface that will not discharge the water to the tank): we are considering two options:
-Option 1: infiltration on site: infiltration wells and/or infiltration pipes
(infiltrate rainwater on the ground).
-Option 2: Discharge the rainwater into a surrounding channel (by
pre-treatment using filters to remove suspended solids).
My question is the following:
Can we achieve the compliance of the credit by this second option, similarly to LEED v3 SSc6.2 credit by using filters with TSS removal rate>80%?
Or we would not meet the credit's requirements because this rainwater is sent outside the Leed project boundary?
Thanks in advance!
