In 3 days, Risanamento Fognature SPA has restored for Veritas SPA the DN 309 mm drinking water pipeline that passes under the historic Ponte dell’Accademia in Venice.
The bridge is currently undergoing restoration, therefore it was possible to intervene to fix with structural relining the 65 m of piping following the arch shape that characterizes this metal bridge.
For the first time in Italy a 2″ patented tapping saddle was installed on the repaired pipe and the piping was tested UNI 805 at 4.7 bar
