Ms Angela Ryan:

They tend to be more complex but are not necessarily the largest. Some of the larger ones, such as in Arklow, have been completed or are almost at completion. I can get the Deputy the figures on the number of houses involved. It is a tiny percentage of the load that Uisce Éireann treats on an annual basis.

The biggest lift in our compliance with the urban wastewater treatment directive will be the closing out of the upgrades to the water treatment plant in Ringsend. That will bring us as a State from approximately 40% compliance with the urban wastewater treatment directive to more than 90% compliance. That project will deliver a step change in that space. With the untreated, it tends to be the very small and more complex cases that are left.
