Utrecht and several surrounding communities are under a boil-water advisory after bacteria were discovered in a local drinking-water storage facility. Water company Vitens and local authorities are instructing residents to boil tap water for three minutes before any use involving consumption.
The contamination involves enterococci, a type of bacteria that indicates the presence of fecal matter in water. This bacteria can cause stomach problems, though the risk is low for healthy individuals. Extra precautions are recommended for babies, elderly people, pregnant individuals, and anyone with a weakened immune system.
Impact on Daily Life
The advisory has prompted widespread operational changes. Many offices and schools in Utrecht have shut down coffee machines and water dispensers as a safety measure. Dutch Railways (NS) and other organizations that use tap water for food and beverage service have adjusted their operations. Health authorities emphasize that properly boiled water is completely safe to use.
The boil-water notice applies to portions of Utrecht, De Bilt, Bilthoven, Zeist, Bunnik, Groenekan, Bosch en Duin, Maarssen, Oud-Zuilen, Tienhoven, and Westbroek. Vitens and local emergency services are publishing detailed maps and regular updates as water sampling continues throughout the affected zones.
How Long Will This Last
Officials have extended the advisory while additional water quality tests are conducted. Before a boil-water notice can be lifted, the water system must produce two consecutive clean test results showing no contamination. Residents should monitor Vitens' official communications for timing updates.

What You Need to Do
When boiling is required:
Boil tap water for 3 minutes before drinking, making cold foods, preparing baby formula, or brushing teeth

Showering and handwashing are safe—just avoid swallowing the water
Dishwashers can be used on hot cycles; for hand-washing dishes, rinse with boiled or bottled water
What Caused This
Vitens identified bacterial contamination at a water storage facility that supplies parts of the Utrecht distribution network. Technical teams are currently flushing and disinfecting pipes throughout the system while conducting extensive water quality sampling to verify when normal operations can resume. Some retailers reported brief increased demand for bottled water but have asked customers to avoid panic buying.
