The drawing above shows 10,000 litres of water as 66.7 full bathtubs: each icon represents 1 full bathtub (150 litres). It is roughly what you drink in fifteen years.
In other units, 10,000 litres is 10 cubic metres or about 2,642 US gallons. Change the number in the tool or pick another reference for the drawing (glasses, bathtubs, tanker trucks, Olympic pools…) with the "Show" selector.
