Project Overview

The Letterkenny RWSS and Creeslough Water treatment plants were developed for the purposes of removing approximately 30,000 people from the Environmental Protection Agency’s Remedial Action Lists (RAL) by providing an adequate barrier for Cryptosporidium removal and inactivation.

Further the construction of the new WTP, Glanua and MEIC  works involved the replacement of approximately 4.5 kilometres of water main from the water supply sources to the new water treatment plant. In addition, approximately one kilometre of trunk main and distribution main at Goldrum Water Treatment Plant was also constructed.

Finally, the works included the upgrade of pumping stations and intakes and the decommissioning of the existing Letterkenny Water Treatment Plant. The Letterkenny WTP works were done in conjunction with the construction of a new water treatment plant in Creeslough, Co Donegal, which was also completed last in 2019.

The new treatment plant at Goldrum now ensures that there is a barrier in place for cryptosporidium and that the water being produced meets all parametric values as specified by European Drinking Water regulations. A big thank you to all of our partners in the construction of this project.
