Water saving tap aerator

Water saving tap aerator

We have reduced our bathroom tap water consumption in hundreds of liters every year by installing an inexpensive water saving tap aerator.

Most of us understand the importance of saving water so we do our best to close the water taps while not in use and teach our children that water it is very valuable and must not be wasted.

Still, as a parent, I have came to realize that very small children (and some adults) may not have yet enough awareness so we need to take a more active role into making sure that water is not being wasted.

Because of the strong water pressure at home, our bathroom tap was using much more water that necessary for just simply cleaning the hands or brushing the teeth. We were wasting water and money!

Saving water

I came across a water saving tap aerator that claimed to use only one litre of water every 3,8 seconds and had very good reviews so I decided to give it a try.

If you also decide to install a water saving tap aerator, my advise is to look for aerators that specifically describe the water usage (for example, one litre of water every 5 second) and to avoid those which make claims like ‘save up to 30%’.

We recently purchased a water saving shower head that claimed to save up to 30% of water. Well, it is actually saving us 1% of water so that means that we have wasted 30 euro that we could had used to buy something else.

In any case, the water saver tap aerator has been a great investment: Low cost, easy installation and big water and money savings.

Standard tap aerator

> Uses 1 liter of water every 6 seconds

> This is the equivalent to 10 liters per minute

> 10 liters per minute x 10 minutes = 100 liters of water per day

> 100 liters of water per day x 220 days per year = 22,000 liters of water per year

> 22,000 liters of water per year x 2 euro per cubic meter of water = 33 euro per year

Note: In Germany are around paying 2 euro per cubic meter of water. Depending on where you live the cost may be different.

Water saving tap aerator:

> Uses 1 liter of water every 15 seconds

> This is the equivalent to 3.8 liters per minute

> 3.8 liters per minute x 10 minutes = 38 liters of water per day

> 38 liters of water per day x 220 days per year = 8,360 liters of water per year

>8,360 liters of water per year x 2 euro per cubic meter of water = 16,72 euro per year

Ways to 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 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.
