After Ireland’s first Nereda wastewater treatment plant in Clonakilty, a second full-scale plant had its start-up in Carrigtwohill in early 2016. According to Process Design Engineer Robin Kraan of Royal HaskoningDHV commissioning and the start-up went very well. “We are ahead of schedule and treat more wastewater than previously planned. Partly due to a well thought out design in cooperation with Nereda licensee for Ireland, EPS, the lessons learned from previous projects have led to a beautiful robust plant with a well oiled commissioning.”

Cooperation between partners pays off

Operator of the Nereda plant in Dinxperlo Mr. Henri Schreurs of the Dutch water authority Waterschap Rijn en IJssel was part of the Royal HaskoningDHV team during the start-up of the Nereda wastewater treatment plant. Robin Kraan: “Outside the united acceleration between the water authority and Royal HaskoningDHV, the knowledge and cooperation with partners has begun to bear fruit. We now know each other and really understand the added value of the three parties, a perfect symbiosis for the smooth start-up of Carrigtwohill.”

Sustainable wastewater treatment technology brings advantages

The biological treatment process brings performance benefits alongside cost and sustainability advantages. The new plant will therefore help Irish Water meet the requirements under the European Union Urban Wastewater Treatment Directive to improve health, water quality and the integrity of the environment. Together with a third Nereda plant – Cork Lower Harbour – these plants will be purifying the wastewater of a quarter of the population of County Cork – the second most populous county in the south of Ireland –  and bring an end to untreated discharges and unpleasant odours.
