We were at IKEA with my wife. During a stop at the toilets, I noticed that when washing my hands, the water flow was more like a nice tiny shower instead of a big flow of water. Smart! That must save a lot of water I thought.

Once I was out of the toilets I noticed a poster that showed that you can do the same at home with a tiny black thingy that you add to your tap.

That tiny thing that is called a mist nozzle cost around five bucks and saves up to 95% of water depending on how you use it (1)!

Spend five bucks, save 95% of water.

That's a good deal.

After installing it at home to see how easy it's to install and how it feels, we are now buying this for every sink that is in the home, and even for the whole building we are in.

Action question

What are simple tools you can add to automatically reduce your consumption without even thinking about it?

Footnotes

(1) According to IKEA "The ÅBÄCKEN mist nozzle uses up to 95% less water in mist mode and 66% less in spray mode compared to a standard wash-basin mixer tap with a water flow rate of 5.7 l/min. So you also save energy on heating water."

Daniele's notes

• This is the first shitty draft of this principle

• This principle might one day make it in the fifth book in the "Service Design Principles" series that explores how to better serve humans and the planet.

• If you're curious about service design principles, you can get the four previous books in the series, with proofread principles and less grammatical creativity.
