Frequently asked questions
What counts as direct water use?
Showering, washing, drinking, cooking, and other direct household water consumption.
Does this include the 'virtual water' used to produce food and goods?
No — this is direct usage only. Virtual/embedded water footprints from food and products are typically calculated with more detailed lifecycle data.
Where can I find my average daily water use?
Check your water bill for total usage, then divide by the number of days in the billing period.
How can I reduce my water footprint?
Shorter showers, fixing leaks, and water-efficient appliances are common ways to reduce direct household water use.
