Flensburg Races to Protect €600,000 Lightning Detectors From Flood Damage – Insurance Options Under Review
FLENSBURG, GERMANY – The city of Flensburg is scrambling to assess the vulnerability of its newly installed lightning detection system to potential flood damage, just months after a historic storm surge crippled the previous generation of equipment. This breaking news comes as the city evaluates insurance options for the €600,000 investment, highlighting the growing challenges of protecting critical infrastructure in a climate increasingly prone to extreme weather events. This is a developing story with significant SEO implications for local and national news coverage.
New System, Familiar Threat
This spring, Flensburg unveiled four modern lightning columns, two strategically placed in areas particularly susceptible to flooding: the central bus station (ZOB) and Hafendamm, near the harbor. The previous lightning detector on Hafendamm, a simple “flash box,” was completely destroyed during the record-breaking October 2023 flood, reduced to a graffiti-covered shell. The incident prompted questions from the CDU parliamentary group regarding the flood protection measures for the new, significantly more expensive system.

IP65 Protection – But Not Floodproof
City officials responded to inquiries by stating that the new columns meet the IP65 standard, offering protection against jet water from all directions. Furthermore, the sensitive measurement technology within the columns is positioned at least 85 centimeters above ground level. However, a crucial caveat remains: the system is not designed to withstand complete immersion in water.
“The columns are not protected against immersion. Such a protective level is not offered by the manufacturer,” the city explained. “This is due to the fact that the electrical lines come out of the ground. If there are flooding, these lines are in the water. The house connection box, which is supplied with electricity, is also not protected against underlying.”
Understanding IP Ratings: A Quick Guide
IP ratings, like IP65, are crucial for understanding the level of environmental protection offered by electrical enclosures. IP stands for “Ingress Protection,” and the numbers indicate resistance to solids (first digit) and liquids (second digit). IP65 means “dust tight” and protected against water jets. While robust, it doesn’t guarantee protection against prolonged submersion. For truly floodproof equipment, higher ratings like IP68 (complete and continuous submersion) are required, but often come with significant cost increases and technical challenges.
Short Circuits Safeguarded, But Damage Still Possible
While the measurement technology is protected from short circuits by multiple FI control switches, the city acknowledges that damage remains a possibility if water levels exceed 85 centimeters – a height surpassed during the October storm surge, which rose over a meter above the harbor quay. Currently, the administration is actively seeking insurance quotes to cover potential damage to the measurement technology, specifically focusing on whether “elementary damage” is included in potential policies. No offers have been received at this time.
This situation underscores a broader trend: municipalities are increasingly facing difficult decisions about balancing infrastructure investment with the escalating risks posed by climate change. Proactive flood mitigation strategies, including raising electrical connections and investing in more robustly protected equipment, are becoming essential, but often require substantial financial resources.
The city of Flensburg’s response to this challenge will be closely watched by other coastal communities grappling with similar vulnerabilities. Staying informed about local weather patterns, understanding IP ratings, and proactively exploring insurance options are vital steps in protecting critical infrastructure and ensuring public safety.
