Ballymore Eustace Water Treatment Plant

Project Outline

Ballymore Eustace is Ireland’s largest water treatment and is a critical piece of infrastructure.

Murphy were contracted by Dublin City Council to deliver all MEICA construction and commissioning works for the upgrade and expansion of this plant from an output of of 274MLD to 318MLD with a maximum capacity of 400MLD.

This project entailed delivery of a full integrated solution comprising both the construction and commissioning of additional process treatment units and the phased withdrawal, refurbishment and recommissioning of existing treatment infrastructure.

Key Challenges

The key challenge in this project was to ensure that the expansion in capacity was constructed, commissioned and integrated in a safe and efficient manner that did not disrupt plant output. This was achieved through close collaboration with the plant operators (Dublin City Council) and their appointed designers in the planning and execution of each stage of project delivery.
