Ballylumford Power Station extracts sea water from Larne Lough for use within the facility. The Reverse Osmosis (RO) Plant Room processes the extracted sea water into deionised water. The deionised water is used as the main coolant on the main generation turbines. The existing dual media carbon steel trunk header pipework (350mm dia) entering and exiting the eight filter vessels via 150mm control station pipework had developed leaks and localised failures due to destructive aqueous corrosion.
The prolonged drought conditions of summer 2018 necessitated rapid mobilisation works to facilitate treated water supply to the Aughnagun Command Reservoir in South Down. Working on collaboration with the NI Water Project Management and Newry Networks Teams Nu Line Utilities worked around the clock to deliver the bulk water transfer, pressure, flow and inlet control system upgrades adapting the existing supply infrastructure to the Mayobridge facility.
