Common split is bottom Rad hose, but as said by all the guys above you need to diagnose for leaks at first (cheap option). Then check the oil dipstick for grey/yellow slush....and check for similar residue under oil cap (although oil cap is not 100%).
Fill the water reservoir and let it idle without the cap on and see what is happening......if it starts to disappear have a look at the exhaust and see if its coming through there??
Plus just how much water are you losing, have a measure with a measure jug and then post your results on here inc how long you kept the car running did you rev it if so how long? and at how much revs....etc etc.

Pressure test would be a good start, chances are if you have a small leak under pressure whist the engine is hot it will evaporate quickly leaving little trace other than a near empty header tank.
Failing no visible leaks found and pressure test complete, then further investigation into possible head gasket issue.

sounds like head gasket has gone puting air into the system causeing to much pressure therefore going into your overflow. Had this when my HG went.
Or you have air in the system, your heaters working?
Also check your bottom rad pipe, if this is rock solid then again it's ya HG,
If this is the case id get a sniffer test done to make sure.

sounds exatly the same as mine started blowing water out of the overflow looks like head gasket not a bad job to do yourself if you are good with the spaners but the motor will have to come out sorry mate

Im having a similar problem with my V1 STi. My temp guage is rock solid where it is supposed to be, the heaters are working as usual, cant see any cracked pipes and the rad is practically brand new, no sign of water in oil or oil in water. Im getting it presure tested tomorrow, and i am praying it is not the HG. I am getting leaking on the ground from both sides with most of it appearing to come from the header tank (these are notorious for leaking in early scoobs).

HG doesn't alway go Water - Cylender
Can also go Gases from cyl - water system, causeing it to over presserize therefore kicking it out of the overflow.
HG on your own will take about 5-7hours engine has to come out + inlet etc of. Use new head bolts + a good gasket.
