Irish Water insists that a recent problem at its Clonaslee plant which caused a big disruption to local supply was caused by a 'minor fault' and resulted in no risk to health.
The State-owned company said the water supply for part of the Tullamore Public Water Supply Scheme and the Clonaslee Public Water Supply Scheme is treated at the Clonaslee Water Treatment plant.
“A minor fault occurred at this plant on Tuesday, May 17 which resulted in an increase in chlorine dosing of the drinking water produced for a limited period of time. This fault was quickly identified and rectified by Irish Water,” it said.
The company did not flag any safety concerns at the time.
“The HSE was contacted by Irish Water through its agents, Offaly County Council and Laois County Council and following the advice of the HSE flushing of the water mains was carried out.
“This resulted in some disruptions to the water supply to customers on Friday 20, Saturday, May 21 and Sunday, May 22 in Clonaslee Village and surrounding areas. Approximately 346 properties are connected to the Clonaslee Water Supply.
“It should be noted that there was absolutely no health risk to the water supply in the area and that the water supply was fit for consumption at all times. The alternative water supply was available to customers who may not have wished to consume the public water supply while the flushing of the system was being carried out,” said the company.
To advise customers of the work being carried out, Irish Water said it placed a notice of these disruptions on its website and all customers who contacted their call centre were provided with all relevant information.
“Irish Water apologises to customers for any inconvenience caused and thanks them for their patience while we worked to fully restore supply to all customers,” it said.
There were several complaints on social media about the problem. Some were not happy that the internet warnings were given, while others said there is an ongoing issue with the quality of the water.
Laois County Council said private wells were not affected and a boil notice was of no help to householders.
Last year Irish Water confirmed it was responsible for a major fish kill in the River Clodiagh near Clonaslee.
