Due to the age of the Athlone WWTW and the number of upgrades over the years, much of the infrastructure has fallen into disuse. In each case the demolition will entail locating, exposing and protecting existing services, rerouting existing services where applicable, stripping and placing of redundant mechanical and electrical equipment, demolition of the civil structure to its full depth and making good the area.

A new Blower House Complex is required that will form the central process controller hub for the Athlone WWTW. The complex will include new civil infrastructure for the new electrical intake substation, generators and power factor correction facilities. It will also include new mess facilities, ablutions, kitchenettes, offices and a laboratory and meeting facilities for process controllers.
