How to use this tool
For flowing water, enter liters per minute and minutes per event. For a fixed-volume event, enter liters per event. Use occurrences per person per day, or set people to one for a shared appliance and enter household occurrences. The result covers that activity for the number of days entered. Use one day for a daily estimate.
