A multi-agency response, also involving An Garda Síochána, the National Ambulance Service and Rescue 117, was enacted following reports at approximately 10.40am of a person in distress who had entered the water in an area of The Quay close to OfficeMaster in Waterford City.
The woman was successfully located and rescued from the water by crews from Waterford City River Rescue and taken onboard the Lenny O’.
The casualty was handed over the the National Ambulance Service for treatment and transfer to hospital.
In a statement, Billy Gallagher of Waterford City River Rescue said: "We wish the person involved a speedy recovery. Thank you to everyone involved and to the Irish Coast Guard for their coordination of this incident with a very successful outcome. Thank you to everyone who called 999/122, your quick actions helped to achieve a very positive and successful outcome this morning."
He added: "We would like to reiterate the absolute importance of an early call to the Emergency Services for water incidents so the relevant services can be dispatched promptly. Please remember if you see anyone in difficulty on our lakes, rivers or coast, call 999 or 112 and ask for the Irish Coast Guard who will dispatch the services needed to the scene - do not assume somebody has already made that call."
