- How much water does a bathtub hold -

On average, a bathtub holds between 130 to 190 liters on water. That is around 80 gallons.

Bath tube water usage

If you want to know how much water your bathtub is using, you need to :

– First make sure that nobody else is using water at home (e.g. tap water, washing machine,…)

– Record your meter reading water consumption value

– Fill up your bathtub (have a nice and relaxing bath… with lots of bubbles)

– Record your meter reading water consumption value again

– Substract the values

Note that most probably you will have two water meter readers at home, one for cold water and another one for hot water. You will need to record both meter reading values, before and after filling your bathtub.

If you need more information about what a water meter is or how to read a water meter, have a look to this post or the video below.

Water conservation - Save and conserve water

Water conservation can be defined as the decision and the act of using less water 

-Water conservation both benefit you and the environment  

The act of saving and conserving water does benefit you because you will be paying less on your water bills. 

And it also does benefit the environment because conserving water prevents any unnecessary waste of natural resources.

Now, at individual level it may not look worth to try to save a few litres or gallons here or there. 

Still, every little counts and if hundreds or thousands of us do save a little every time, it will make an important contribution towards conserving our natural resources.

 

For example, if 9000 households would manage to save as little as 5 litres of water per day:

  • Collectively, we would be saving over 16,000,000 litres of water per year!
  • Collectively, assuming a cost of 2 euro per cubic meter of water, we would be saving nearly 33,000 euro per year.
It is clear that small water savings do really count when looking into the bigger picture.
