I think people who are still on water rates rather than meters will have less incentive to be 'water aware', but we should all do our best not to waste water.
Water should never have been privatised in my opinion, and Thames Water is one of the worst. It even borrowed money to pay its shareholders, racking up debt at an horrendous rate while failing its customers left right and centre. Yes I'm angry at the un-repaired water leaks, the sewerage spills etc. and will raise a cheer if it does come back under public governance.
