Most places, when a water main bursts under the city streets, you're looking at a world of trouble. Traffic back-ups. Property damage. Business shut-downs.
Not so in Venice. It took a while before anyone even noticed the huge pipe rupture near Fondamenta Nuova that caused untold thousands of gallons of precious drinking water to blast into the lagoon last October 21st. Even then, it took Vesta (the public utility that handles water management) 5 days to fix it.
