A major power outage in Zürich, specifically at the University Children’s Hospital, briefly forced staff to activate backup systems and contact other hospitals. It happened on Thursday afternoon, 25 June 2026.
Meanwhile, a separate outage in the city led to untreated sewage spilling into the River Limmat, a famous summer spot for locals.
For Zürich’s children’s hospital, the episode was disruptive but short-lived. For the city, the sewage spill underscored the broader vulnerability of critical systems when power supply is interrupted.
In both cases, authorities said safety systems held, and no immediate danger to patients or the public was reported.
Parts of Hoengg and Oerlikon also lost power for over two hours last week, causing distress to residents already facing an intense heatwave.

CEO Georg Schäppi Said There Was Never Any Danger To Patients’ Lives Or Health
At the children’s hospital, the blackout struck at around 3:15 p.m., prompting an immediate switch to technical emergency procedures. CEO Georg Schäppi said there was never any danger to patients’ lives or health, and that diesel generators were brought online later to keep the hospital running. The hospital has since returned almost fully to normal operations. Schäppi said staff had prepared for such an incident through regular drills, adding that a hotline was opened for worried parents. The cause of the short circuit remains under investigation.
Hospital managers also contacted other hospitals as a precaution and scaled back emergency-department operations to reduce risk during the outage. That step ultimately proved unnecessary, Schäppi said, because all patients could remain on site and normal operations will continue.
Sewage Overflows Into River Limmat After Power Outage In Zürich
The incident came on the same day as a separate power failure in Zurich that caused sewage to overflow into the River Limmat. Swissinfo reported that the outage led to a spill from the city’s wastewater system, raising environmental concerns even as authorities worked to contain the disruption. Together, the two incidents highlighted how quickly a single technical failure can ripple through both healthcare and urban infrastructure.
