Frequently Asked Questions

What is "hidden" water?
Virtual water — the water used to produce the things you consume. Your visible water (130L/day in DE) is what comes out of the tap. Your hidden water is in your food, clothes, electronics. A single t-shirt = 2,700L. A burger = 2,400L. A coffee = 140L. Hidden water is 90-95% of your real footprint.
Are these numbers really that high?
Yes. Source: Mekonnen & Hoekstra 2011, updated by Water Footprint Network 2024. They include irrigation, processing, transport. A pair of jeans = 7,500L because cotton is thirsty AND grown in arid regions, AND processed with water-intensive dyes. The number is real even if the math feels insane.
How do I reduce hidden water?
Highest impact: (1) Eat less beef (1kg = 15,000L vs 1kg lentils = 1,250L) -30-40%. (2) Buy fewer/longer-lasting clothes -10-15%. (3) Choose seasonal local food -5-10%. Direct water savings are real but small (4-min showers, low-flow toilets) — change diet & wardrobe to actually move the number.
Why does this matter when I have plenty of tap water?
Because most virtual water comes from regions with water stress: Spain (almonds), Pakistan (cotton), California (almonds, beef), India (rice). Buying these products = importing water from drying regions. Your hidden water is exporting water-stress to other countries.
