Improving Water Quality

The Dublin Bay Project is one of the largest projects ever undertaken by Dublin City Council. It comprises of three main components:

  • The Ringsend Wastewater Treatment Works
  • Sutton Pumping Station 
  • The submarine pipeline under the bay to bring wastewater from North Dublin to Ringsend for treatment

All of these components are now fully operational resulting in a vast improvement in the quality of water in Dublin Bay.

Design, Build, Operate

The Ringsend Wastewater Treatment Works was one of the first examples of a Public Private Partnership (PPP) in the state. It was decided to use private sector expertise to design, build and operate the Works as efficiently and economically as possible. The Works is now being operated by Celtic Anglian Water.

Biofert and Methane

Sludge is a by-product of the wastewater treatment process. At Ringsend it is treated and dried at temperatures of 450 degrees Celsius, killing all the pathogens and producing a pasteurised, organic based fertiliser. It is marketed under the name “Biofert” and spread on tillage and grass in Leinster.

A further by-product of the treatment of this sludge is methane gas, which supplies over 50% of the heat and electricity required at the Ringsend Works.
