Wiesbaden under water alarm: boiling order due to enterococci until Tuesday!
There is currently excitement in Wiesbaden: the city administration has issued a boiling order for tap water. This affects the entire population, with exceptions for the districts of Amöneburg, Kastel and Kostheim. The reason for the drastic measure is the discovery of enterococci in a water sample taken on Wednesday, October 29, 2025. Citizens were informed about the situation on Friday evening, October 31st. The boil order is expected to remain in effect until at least Tuesday, November 4, 2025 and will apply until there are three negative results from the health department.
What is enterococci and why are they so worried? Enterococci are spherical lactic acid bacteria that occur in the intestinal flora of humans and animals. Among other things, they support the digestive system and can help in the production of certain foods. However, some types of enterococci can also cause illnesses such as urinary tract infections or even serious illnesses such as blood poisoning. As an indicator of fecal contamination, they are particularly critical, as their presence can indicate other pathogens, as can be seen from the information provided by Vitalhelden.
Precautionary measures for the population
The city administration strongly recommends boiling tap water before drinking, brushing your teeth, preparing food and making ice cubes. Under no circumstances should unboiled water be used to prepare fruits, vegetables or salads, even for medicinal purposes. Washing dishes and laundry should also only be done with boiled water.
The causes of the contamination are still unclear. Possible factors could be technical malfunctions, accidents in the pipe network or old sewers. To ensure water quality, additional samples are taken from the distribution network. The city is also checking whether chlorination of the pipes is necessary for disinfection.
Who is particularly affected?
People with weakened immune systems, seniors, infants and people with chronic illnesses are particularly at risk from enterococcal-related health risks. According to Vitalhelden, the water remains invisible and odorless to the population - microbiological laboratory tests are required to detect the contamination. Therefore, it is important to take the city's warnings seriously and follow recommended precautions.
The next few days will be crucial to restore water quality and inform the population promptly about the results of the control tests. Until then it's better to be safe than sorry! Further information is provided by local news agencies that are already reporting on the situation, such as MainzUnd and Vitalhelden.
