Updating property address any municipal bill implications!??

In terms of resolving the change of address issue they probably deserve 5 stars, but I was ignored when it comes to the pertinent question I asked which still bothers me to some extent and have never been provided with proper feedback. That is the issue of the water bill being perhaps modelled on the address incorrect address identifying my property and points to another plot because at some point 2019 or so my water bill just shot up exponentially.
