You cant stop the economy ticking though thats the crux of it.
However by stopping hosing they really dont do much preventation of the issue if many dont use them anyway. Although it only takes one its lot water consumption.
- Shower - 35 litres
- Bath - 80 litres
- Brushing teeth (tap on) - 6 litres/min
- Brushing teeth (tap off) - 1 litre
- Toilet - 7-9 litres
- Washing machine - 65 litres
- Dishwasher - 20 litres
- Washing car with bucket- 10 litres
- Hosepipe/sprinkler - 540 litres/hour
It maybe needs businesses reclye water bit more but it then needs filterisation process nobody turn up for dirty water car clean.
There article in beeb our only options one was huge migration from south east to more afluent water areas. Arthur do fancy living lake district or scotland. Get all the water you can drink and use
