Inlet

Curb line

As filtered water passes to the bottom of the box the under drain pipe constriction flows forcing water to go into the storage vault. Both the vault and the filter box have holes in the bottom to allow for infiltration. Additional infiltration / storage capacity can be obtained by placing the entire system on an extensive gravel bed. Eventually the entire system would drain via infiltration or through the under drain pipe.
