Another way of detecting water that I have seen is:
Use one of those little microswitches with the steel lever which pushes down 
the microswitch, position the lever on top of an aspirin tablet laying on the 
floor.

A small amount of standing water melts aspirin tablet, allowing the 
microswitch to close.

If you get to have a valve controlling the main water pipe, it's easy to
create a water sensor using just 2 copper wires or screws which touch
the floor and detect any conductive liquid between them. Both device can
be easyly connected to a PC.
