Ways to water conservation

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.

If we could reduce our washing machines water usage, even a very small amount, it would make a big impact on preserving our natural resources.


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

> Collectively, we would be saving over 16,000,000 liters 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.
