After the holidays: turn on the tap
When tap water stands for a long time during the holidays, germs and deposits can form. Therefore, let the water run for a few minutes before drinking it.
During the holidays, most offices, laboratories, and break rooms at ETH Zurich remain empty. During this time, the water in the pipes often stands still, which can promote the formation of deposits or germs.
To ensure that you can enjoy your drinking water again without hesitation, the following applies especially now: When using the tap for the first time after the holidays, let the water run for one to two minutes until the temperature is constant. Also, don't forget to replace standing water in coffee machines or kettles.
Incidentally, this recommendation also applies after shorter periods of standing, such as after a weekend.
ETH recommendations for tap water:
- Let the tap run briefly before drinking until the temperature is constant – especially after prolonged periods of non-use.
- If the water is cloudy or discolored, let it run longer until it is clear.
The Facility Services team wishes you a good start to the new year!
