project description:

The project is a 400,000 PE upgrade of Ringsend WwTP using innovative Aerobic Activated Sludge (AGS) technology. The AGS system avoided the need for a 9km long sea outfall thus saving close to €1billion in public funds. It includes a 110m*36m*20m Main Reactor Block on piled foundations in poor ground and a 15m*10m*6m deep Expansion Lift Pump Station above buried structures. The upgrade treats 2,5000 l/s of high quality effluent. In addition to providing major environmental improvement to Dublin Bay, the project unleashes significant development potential in the Capital City.
