The Lough Mask regional water supply has been removed from the most recent Environmental Protection Agency’s (EPA) Remedial Action List (RAL), however, Kiltimagh and Inisturk public water supplies remain on the list. That’s according to Irish Water.
Up to 40,000 people in this region, whose water is supplied through the Lough Mask scheme have had their water supply removed from the EPA’s to-do list.
The scheme was on the RAL for treatment and management issues at the plant which have now been addressed following a €1.9 million upgrade by Irish Water working in partnership with Mayo County Council.
The works were carried out over the course of a year by Murphy Engineering Ltd as part of an overall upgrade and expansion of the water treatment plant at Lough Mask.
According to Irish Water, the plant is now fully compliant with all relevant regulations and will soon be supplying water to Williamstown in Co Galway and Ballinlough/Loughglynn in Co Roscommon as well as continuing to supply a large section of Co Mayo.
The Kiltimagh water treatment works are also on the RAL and Irish Water say the plant is undergoing upgrade works to the disinfection system while the water treatment processes are being optimised.
The third Mayo scheme on the RAL is the Inishturk public water supply which is on the RAL for high levels of THMs. According to Irish Water, a contractor has been appointed to carry out the necessary works with the project due for completion in March 2018.
THMs, or Trihalomethanes are chemicals formed by the reaction of naturally occurring dissolved organic material and chlorine which is used for disinfection in order to protect against pathogenic bacteria.
