Setting aside those with a need for a lot of water, because their families are large, disabled or incontinent and they are on UC.

When water is a scarce commodity that needs to be used carefully. The best way to do this is to make some charge for water. Even before water meters, many water companies put a supplement on your bill if you used a hose or sprinkler.
In the UK, where water is scarce, we are always being encouraged to economise on water, shower don't bath, only use washing machines and dishwashers when full etc etc and it is noticeable these days, when water is on meters, there are far fewer people using sprinklers every day to keep their front lawns immaculate.
