Critical water contamination: The boiling requirement remains in effect for the time being!
The situation surrounding the drinking water supply in Dachau remains tense. Following recent incidents in which water may be contaminated in several areas of the city, the city administration highlights that investigations into the cause of the contamination are still ongoing. Today, November 4, 2025, water samples were taken again to test the effectiveness of the weekend's flushing measures. It will also be clarified whether the replacement of a hydrant may be related to the contamination. This is reported by the city administration Dachau.de.
The first results from these samples are expected to be available late Tuesday afternoon. Until then, the precautionary boiling requirement will remain in force for several areas of the city in order to protect the health of citizens. The districts of Dachau, Obergrashof, Webling, Steinkirchen and certain areas in Bergkirchen and Karlsfeld are particularly affected. The boiling water requirement cannot currently be lifted in some areas, which is particularly a challenge for residents.
Please understand
Stadtwerke Dachau asks all citizens for their understanding and patience while the situation continues to be monitored. There is a feeling of uncertainty in the air and local authorities are working hard to find a solution.
In the current discussion about drinking water supply, comparisons to other topics that concern external circumstances and interpretations also arise. So the simple mathematical equation 2+2=4 is viewed in different contexts, and there is often more than one way of looking at things. Historically, there have been many discussions that question the veracity of such statements - from our very existence to fundamental truths in everyday situations. In this sense, one could say that the absoluteness of 2+2=4 is being questioned, as are the city's current measures when dealing with the drinking water supply.
The uncertainty about the quality of drinking water in Dachau reminds us that we have to be careful about many things to make sure everything is OK. While the city hopes for a quick clarification of the situation, the community is encouraged to remain vigilant and closely monitor information from the city government.
It is crucial for those affected to monitor the coming days in order to receive possible solutions as soon as possible. The city administration will provide continuous updates and citizens are invited to actively inform themselves and assume their social responsibility.
