Hi,

We in Sweden have standard WC's that have a dual flush for 2 and 4 liters which gives us a effective flush on 0,7 GPF, by that we get a reduction on 56 % by doing "nothing". And then we struggles with the faucets for the public lavatory where we belive that the baseline is really low, especially in LEED v4 where sensor-controlled faucets doesn't help us anymore.
Maybe the credit shouldn't be about just wastewater?
