The drawing above shows 100,000 litres of water as 3.3 tanker trucks: each icon represents 1 tanker truck (30,000 litres). It is roughly what 50,000 people drink in a day.
In other units, 100,000 litres is 100 cubic metres or about 26,417 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.
