Irish Water is investigating the discharge of a quantity of wastewater sludge to the River Nore at Kilkenny city yesterday from the Purcellsinch Wastewater Treatment Plant on the outskirts of the city. This discharge is an organic liquid material which is part of the wastewater treatment process.

Irish Water has apologised over the incident.


Immediately upon being made aware of the incident, staff made a number of adjustments at the plant to address the issue and the situation has since stabilised with no further discharges reported.


Irish Water is in the final stages of an upgrade to the Purcellsinch Wastewater treatment plant to bring the aging plant up to modern standards.

This work, which represents an investment of €1.7 million will result in a much improved performance and significantly reduce the likelihood of a similar incident occurring in the future.


Staff from Irish Water and Kilkenny County Council are on site and will liaise with project contractors to monitor the performance of the plant over the coming days. Irish Water would like to apologise for this incident and we will continue to work closely with the EPA, Kilkenny County Council and other statutory bodies to analyse water quality in the area and minimise the impact on the River Nore.
