Full water service has now been restored to Carlow Town following a fuel spill into the Burren that lasted more than three weeks.
Sion Cross Water Treatment Plant had been shut down while the Council and Irish Water tried to deal with the contamination.
For the past number of weeks Carlow Town was being supplied by just two of its three water supplies.
Carlow County Council were notified to an oil spill into the River Burren in the Busherstown area on Thursday the 6th of July and the supply at the treatment plant there was immediately shut off.
Irish Water have now told KCLR News that a new process has been put in place at the plant to provide a specific barrier to hydrocarbons and to protect the public supply.
The HSE was also being liaised with to make sure there was no risk to public health.
The Environment Section of the County Council have also managed to stop the spill into the river, after initially having difficulty in locating the source of it.
Irish Water have thanked customers in Carlow for their patience.
