A "precarious" repair performed during previous work on the gas network: this is the problem behind the major disruptions experienced over the last ten days in Quartu Sant'Elena , where a fault caused potable water to leak into the gas lines. The critical point has been identified and the repair completed, and cleanup and remediation operations are now underway for a gradual return to normality.

To address the emergency, Abbanoa deployed a dedicated task force that has patrolled the area nonstop over the past 10 days, performing over 20 targeted maintenance operations and several systematic leak searches using geophonic instruments and correlators. The network isolation maneuvers led to the identification and isolation of the critical section , locating the fault on Via Napoli, far from the area where the problem had manifested itself in recent days. The investigation, among other things, confirmed that the problem originated from damage sustained during previous work to lay the gas and fiber optic networks by the companies responsible at the time .

On that occasion, a press release from Abbanoa states, " a water main pipe had been damaged during excavation work, but the repairs by the company installing the gas and fiber optic lines had not been carried out in compliance with technical standards: a plywood connection had been improperly repaired with a polyethylene section and single-joint joints not rated for the nominal pressure. The failure of this "precarious" repair caused the hole in the nearby gas main, causing the network to flood."
