Nereda® WwTP
Cork Lower Harbour

The contract for the design, build and operation of this treatment plant was awarded to an EPS & SISK Joint Venture in 2015

Project Title



Irish Water



About the Project

The EPS & SISK JV utilised the innovative Nereda® process that won the 2016 Green Technology Award in the design of this plant and relied heavily on off-site BIM manufacturing techniques to achieve the challenging targets. Live flows were received to this new treatment plant from December 2016. 

The process proving test period was completed in late March 2017 ahead of schedule and to the satisfaction of the client and all other stakeholders involved.

EPS is now operating this prestigious asset on behalf of Ervia and the people of Cork Lower Harbour.

The introduction of the Nereda® process represents a significant and evolutionary step in wastewater treatment technology.  Nereda® combines the treatment characteristics of granular biomass in highly automated sequencing batch reactors, resulting in reductions in footprint, costs, electricity, sludge production, chemical consumption and improved environmental compliance and robustness compared with established wastewater treatment technologies.  
EPS, as the licensee for Nereda® in Ireland, have a co-operation agreement with the global engineering consultancy, Royal HaskoningDHV for the delivery of Nereda in Ireland.  To date, the EPS/Royal HaskoningDHV partnership have already successfully delivered the wastewater treatment plants both in Clonakilty and Carrigtwohill as well as the successful pilot plant for Ringsend WwTP.
