About the Water Usage Calculator
Create a simple household or group water-use projection from a stated daily assumption.
Formula
Total liters equal people times daily liters per person times days. Average daily group use excludes the number of days.
Example
Four people at 150 liters each per day use an estimated 18,000 liters over 30 days.
Notes
The tool does not determine an appropriate allowance and excludes seasonal or activity-level variation unless reflected in the input.
