p.s. I've been through something similar, where the agreement didn't mention it, and the owner assumed they paid for it so they happily did, until they mentioned it to a property lawyer, which suggested they could put the costs onto the tenant (i.e. me).

The water is in the name of the owner, so I'm not the account holder, but I'm happy to just reimburse the owner based on usage. It hasn't been a problem, and accountability squarely sits on the owner, but the grey area does concern me.

In future, always make sure water & power and any similar utilities are explained in the tenant agreement.
