The water leakage rate in Cork City has halved in recent years.
That's according to Uisce Éireann, which is reporting that upgrade works and leak repairs have resulted in over 17 million litres of water being saved every day.
That's the same as more that over four times the daily household water usage of Cobh.
Supplying the city's population of over 200,00 people means water has to flow through roughly 600km of watermains - enough pipeline to get from Douglas to the Giants Causeway in Antrim.
