Ballygowan is a leading Irish natural mineral water brand available in the UK and Ireland, sourced deep underground from the town of Newcastle West, Co. Limerick. Ballygowan water is drawn from an aquifer deep underground. Atlantic rain falls and takes 750 years to filter through calcium-rich limestone to join our source. We draw this naturally pure water and bottle it. Ballygowan – simply natural, with a uniquely refreshing taste.
