Safe and secure water supply for 19,689 consumers

The Portlaoise Water Supply has been removed from the Environmental Protection Agencies (EPA) latest Remedial Action List (RAL) which was published this week. The analysis on the water supply carried out by Irish Water has ensured that the water supply for 19,869 customers in Portlaoise is safe, secure and reliable.

The water supply was placed on the RAL in 2014 due to a risk for cryptosporidium which is a very real threat to the water supply if the proper barriers are not in place. Irish Water carried out measures to review the risk for cryptosporidium in the supply. A consultant hydrogeologist was appointed, risk assessments were carried out on all boreholes in the supply area to indicate that they are not at risk of cryptosporidium. This work facilitated the removal of the Portlaoise Water Supply from the EPA's RAL. Work was carried out to upgrade the treatment and disinfection processes at the water treatment plant.

Delivering a safe water supply to our customers

Welcoming the removal of the Portlaoise Water Supply from the RAL, Regional Compliance Specialist, Andrew Boylan, said “The removal of the Portlaoise supply from the EPA latest RAL is a confirmation of the focus and collaboration between Irish Water and Laois County Council to establish that the water supply was not at risk for cryptosporidium. The assessments and surveys carried out and reviewed by the Geological Survey of Ireland (GSI) have confirmed that Irish Water is delivering a safe water supply to our customers in Portlaoise. The work carried at the plant means that the water supply is meeting all drinking water standards. As a single utility, Irish Water can take a comprehensive look at the overall performance of Ireland’s drinking water production plants so that when the most serious problems are identified like the issues in Portlaoise projects and budgets can be prioritised.” 

The RAL is updated quarterly by the EPA for those water supplies where investment in treatment processes is required. Irish Water has a prioritised programme of investment for all schemes on the RAL and the current updated RAL, which showed a reduction from 108 to 98 schemes, is a reflection of this progress.
