Morphology
The meaning is compositionally built from 'water' (liquid) + 'tank' (a large vessel), so a learner who knows both words will understand it denotes a container that holds water (here specifically for flushing). This noun–noun compounding pattern is cross-linguistically common and follows standard English composition, making the MWE readily comprehensible to B1 learners.
Etymology
Water tank shows a simple, literal picture: a tank full of water sits above or behind a toilet, and when the water falls it helps clear the bowl. That's why water tank means the container that holds water 'to flush a toilet'.
