The drawing above shows 5,000 litres of water as 33.3 full bathtubs: each icon represents 1 full bathtub (150 litres). It is roughly what you drink in seven years.
In other units, 5,000 litres is 5.0 cubic metres or about 1,321 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.
