Source Civil was appointed as specialist civil contractor by the Main Contractor. Source also assisted in redesigning sections of the planned work to execute the works with minimal disruption and a better quality product for the client.

The works comprised of the following:-
- Site preparation
- Design and build of the Cloghroe pumping station, combined storm overflow tank, storm overflow screen and all associated M+E facilities.
