Project details

The Donaghmore WwTW Scheme involved the upgrade of the existing treatment works with a new facility that utilises Rotating Biological Contactors (RBCs) to treat wastewater. The plant is designed for a population equivalent (PE) of 3000 and produces final effluent (FE) to the standard of 20:30:5 (BOD: SS: NH4-N).

The plant provides a robust system capable of producing high quality effluent with respect to carbonaceous BOD removal and nitrification. The construction of the works was carried out in five phases to ensure that the existing plant performance and consent could be maintained at all times and that daily operations were unaffected. This was especially challenging given the confined space of the site and the close proximity of new plant to the existing, operating plant structures and pipework.
