I wouldn't rely on this. I've had mine weighed - and that was at STN. They DO do spot checks.
With regard to bottled water, you are allowed to bring an empty bottle through security, and can then refill it at the restroom taps airside. I thus only buy about one bottle of water per trip (in the West).
You may well have got away with taking an empty water bottle, but my understanding is that this is not allowed. The rules say that you are not allowed to take liquid containers that hold more than 100 ml, regardless of whether they are full or not. An empty water bottle is the same as one that is half full.
