If you’re a fan of the Olympics, and swimming in particular, you’ll be familiar with the size of the pool (50 m x 25 m). But have you ever wondered how much water it holds and how long it might take for one person to drink it?
Depending on depth, the pool will hold between 1.25 million litres of water (1 m depth) to 2.5 million litres of water (2 m depth). And if you assume we all drink between 2-4 litres of water each day, that would take over 3,400 years for one person to consume.
In fact, many of us will consume all the water in the smaller size swimming pool in just one year. It’s all due to the amount of ‘hidden water’ we consume in our food.
These numbers may be hard to believe but here’s a few examples of how easy it is to build up your water footprint based on three main meals a day – even without dessert!
