Water consumption is largely influenced by daily usage habits. The biggest differences between households usually result from the following factors:
Shower length and frequency
Long showers significantly increase hot water consumption. Even reducing shower time by a few minutes can noticeably lower water use.
Dishwashing habits
Dishwashers generally use less water than washing dishes by hand under running water.
Laundry
How often the washing machine is used affects overall water consumption. Running full loads helps save water.
Toilet flushing
Toilets are one of the largest water users in a home. Dual-flush systems can significantly reduce water usage.
Leaking taps and toilets
Even a small continuous leak can increase water consumption by several cubic metres per year.
Household size and lifestyle
The size of the household, the number of children, and daily routines all directly affect total water consumption.
