As per the last thread, if it is fresh water then it'll be from the air con evaporator drain, these can clog up and the water drains into the passenger footwell instead.
If you lie under the car, put suspension height on extended, and above the gearbox bellhousing on the body either side are rubber drains which look like flower petals, stick your finger or a piece of flexible hose up them and it should dislodge collected debris and realease a torrent of water all over you, then you know the blockage has been cleared.
A quick taste test will determine if it is cooling water instead.
