Where the water really goes
In a flat, showers are almost always the biggest single use, and toilets are second. Together they are usually more than half the total.
The washing machine is third and it is bigger than people think, because a load is around sixty litres and most families run several a week.
Kitchen taps, dishes and cleaning add up to a steady background amount that is hard to reduce and not worth worrying about.
Drinking and cooking, which is what people picture when they think about water use, is a rounding error. A person drinks two or three litres a day out of two hundred.
In a villa with a garden, none of the above matters much. Irrigation can be more than the entire household put together during summer.
