I'll guarantee there's no holes,
If you don't want to disturb the carpet (I wouldn't, if its not falling apart, it will, if you remove it)
remove a bung each side, source 2x 50cm lengths of 8mm tubing, use a hole punch to punch about a 4mm hole in the middle,
thread the hose through the metal hole, aiming to the back of the car, you should be able (with a bit of trial and error) see (feel) the tube in the rear side compartments under the battery and the other side under the harmonic balance weight,
there are drain holes in those areas, so as long as they are clear, the water will drain away,
Now push the grommet over the tube (leaving about 5mm out of the top) and carefully use a screwdriver to poke the grommet back in the hole
