Danger of explosion in the sewage treatment plant: major alarm in Wandlitz on Tuesday!
An incident at the Schönerlinde sewage treatment plant near Wandlitz caused a stir on Tuesday, July 15, 2025. At around 7:45 a.m., a dangerous chemical reaction was detected between caustic soda and hydrogen peroxide, which promptly led to a large-scale operation by the fire department. Around 100 liters of hydrogen peroxide had been mistakenly poured into a 10,000 liter tank of caustic soda, requiring immediate action. At around 11 a.m., emergency services were finally able to consider the incident under control after the entire wastewater treatment plant site had to be evacuated.
The fire department was on site with a large contingent of special forces for dangerous goods. They approached the matter with caution: the liquid was carefully stirred and continuously monitored to prevent further dangerous reactions. In addition, a decontamination section was set up to clean the firefighters' turnout clothing. Two people were taken to hospital as a precaution, and Mühlenbecker Strasse was closed in both directions so as not to endanger the measures.
Investigation of the circumstances
The police were also on duty to monitor the situation and initiate initial investigations. It currently remains unclear whether the incident will result in legal action being taken against the driver of a truck. Alexander Separat, a specialist consultant for hazardous materials systems, supported the implementation of the safety measures and helped to manage the incident quickly and safely.
The sewage treatment plant is operated by Berliner Wasserbetriebe, which also took responsibility for clearing and disposing of the chemicals. The site was handed over to this facility after the completion of the measures in order to restore normal operations as quickly as possible.
Chemical hazards
Such incidents are not only an issue at the Schönerlinde sewage treatment plant, but also affect many companies that handle hazardous substances. The Federal Institute for Occupational Safety and Health (BAuA) offers practical guidance to increase safety in companies. This aid includes instructions and checklists that help companies carry out risk assessments and minimize risks. Well-planned handling of hazardous substances can not only save lives, but also prevent costly accidents. The BAuA provides further information on this at BAuA.de.
In addition, it is important for cities and municipalities to be well prepared in the event of a release of hazardous substances. Dealing with chemicals and their potential hazards is an ongoing area of learning.

Overall, the incident at the Schönerlinde sewage treatment plant clearly demonstrated how important it is that emergency services are well trained and prepared in order to deal with such situations quickly and efficiently.
