How much water can a person consume in a day?
Typically, each person will consume at least 10 liters of water, and the range is 50 liters per person per day.
If you have a dishwasher and washing machine, then they are counted as extra person. Consideration should be given and how often is the usage of the showers if there are any on your boat. When you take into account all the above factors, the following formula can be used to calculate your needs for clean water: the number of persons X liters, divided with working time of your device (hours) gives the calculation of liters per hour.
