Calculation bases and accuracy of this calculator

All our calculations are based on statistically determined values for water consumption, as well as water and energy costs. Of course, there are also deviations from these averages, depending on your particular infrastructure, habits and needs, if these differ significantly from the average values.

Therefore we made these settings editable for you within the expert-settings area.
