Nereda Wastewater Treatment Plant, Carrigtwohill
The contract for the construction of the treatment plant, which involved a circa €12 million investment by Irish Water, was awarded to an EPS – Sorensen Joint Venture partnership in June 2014.
The plant is significant for a number of reasons not least the fact that it is the second plant in both Ireland and the UK to utilise the innovative Nereda biological treatment system.
It can now treat waste for a population equivalent (PE) of 30,000 but has been designed to be able to double this capacity in stages.
The project also involved upgrade works to three outlaying pump stations and a 1.5 km marine outfall.
Carrigtwohill WwTP was successfully handed over to EPS Operations on the 18th May 2016 to begin a 20 year operate contract on behalf of Irish Water.
The Nereda process has made this plant a key learning center for Irish and international clients. It is expected that as well as improved water quality and removal of existing health risks for the community, this new plant will unlock the capacity for further development in one of Cork’s fastest growing satellite towns.
