About the Clonakilty Nereda WWTP

Ireland’s first wastewater treatment plant using Nereda technology is Irish Water’s Clonakilty plant in the south of the country. The old plant has been completely overhauled and the Nereda technology is quadrupling its capacity to 20,500 p.e. It treats the effluent to a far higher standard than the original plant using significantly less energy and produces less sludge. The lower nitrogen and phosphorus content in the effluent brings to an end the problem of unpleasant odours in Clonakilty Bay.The wastewater treatment plant in Clonakilty is the first plant constructed in the world that is built mostly underground to minimise the visual impact.Based on the outcome of a public tender process, EPS was awarded a 20 year DBO Contract which provided for the design, construction, commissioning and operation of an upgrade to the municipal Waste Water Treatment Plant at Clonakilty. EPS selected the Nereda technology in agreement with the state water authority in Ireland, Irish Water (established in 2014) The plant in Clonakilty is came operational mid 2015.
