Hello Tia, The simple truth ...

Hello Tia,
The simple truth is that you do not need further treatment on utilities-provided water. In the UK, where I believe you are located, the domestic tap water supply is of an excellent quality. The only possible cases where you may want to add some form of treatment is in old buildings where you may still find lead pipes (I have no data on this, it's possible there are still some out there), and if the taste of chlorine is too unpleasant for you.
Another important point: some commercial buildings and some housing buildings occasionally use drinking water storage tanks as a buffer to ensure continued supply to the taps. This can have detrimental effects, particularly if the tank is oversised compared to usage. This can lead to bacterial issues. See Legionella Control Association's Approved Code of Practice - L8 for guidance in this case. For most UK housing though, this is not the case.
