Hamburg, October 1 – A major water main break near Hamburg’s main train station on Wednesday afternoon caused extensive flooding and significant disruption across several city districts. Firefighters and technical relief services were deployed in large numbers to manage the situation, which also saw a separate water main burst at Ohlsdorf Cemetery.
City Center Submerged: Amsinckstraße Heavily Damaged
The primary incident occurred on a main water line in the city center, specifically affecting the Amsinckstraße. The rupture led to the flooding of numerous basements and underground car parks, with some individual houses experiencing smaller pipe bursts. Parts of Amsinckstraße visibly subsided due to the water, and several roads were submerged. The water flow was eventually stopped late in the afternoon, with Hamburg Wasser confirming the broken line in Amsinckstraße was sealed with a shut-off valve. No injuries were reported.
Firefighters worked into the evening, employing large pumps from the Technical Relief Agency (THW) to clear water from affected areas. Unimogs from the volunteer fire brigade with water tanks were also on-site. Cleanup efforts, including the removal of sludge, continued late into the night.
Cause Under Investigation
The cause of the break in the 60-centimeter-thick main water pipe remains unclear. A specialized company is tasked with assessing the damage. Before they can access the damaged pipe, water in the meter-deep hole around the break on Amsinckstraße must be pumped out, a process expected to continue into the night.
Impact on Water Supply and Ohlsdorf Cemetery
The incident led to a significant drop in water pressure across several districts, including Neustadt, Hamm, Winterhude, Barmbek, and Eilbek. Norderstraße in the Münzviertel was also flooded, and numerous city center roads were closed. Hamburg Wasser confirmed the pressure drop early Wednesday afternoon. By late afternoon, the fire department and police issued an all-clear, stating that water pressure was rebuilding, and by evening, it had returned to normal levels. Two water tankers were deployed to provide emergency supply to a street where some households were still experiencing restrictions.
Due to the pressure fluctuations, residents may experience turbidity in their tap water. Hamburg Wasser explained that natural iron and lime deposits on the inner walls of the pipes could loosen, causing discoloration. However, this is not considered a health risk.
Earlier on Wednesday, another water main break occurred at Ohlsdorf Cemetery, directly in front of the main entrance. Water flowed onto the adjacent Fuhlsbüttler Straße. Hamburg Wasser shut off the water and is working to repair the damage. The company stated that a connection between the two incidents is unlikely, as they are located in different pressure zones.
Road Closures and Future Plans
Both Fuhlsbüttler Straße and the adjacent Alsterdorfer Straße remain closed in the affected sections. Numerous roads in Hamburg’s city center are also impassable, including Spaldingstraße and Willy-Brandt-Straße. Hamburg Wasser anticipates that Amsinckstraße, having been undermined, will remain closed for several days as repair work continues.
