§ What happened
A malfunction occurred at the Cantina Settecani winery due to a faulty valve in the bottling line washing circuit.
1,000 liters of Lambrusco Grasparossa wine entered the town water pipes under pressure.
Wine flowed from faucets and showers in about 20 homes for roughly three hours on a Wednesday in March.
The local government stated the leak did not pose health risks.
Why it matters
The event provided brief levity during the coronavirus crisis but illustrates how equipment failures at industrial sites can allow unintended substances to enter drinking water distribution systems.
◇ Prevention lesson
Regular inspection and proper isolation of processing equipment from potable water lines helps prevent unintended cross-connections.
