€1m water treatment plant upgrade by Irish Water to bring many benefits to Glenties and Ardara businesses and residents

Irish Water has commenced work on a €1 million upgrade of the Glenties Water Treatment Plant in Co Donegal which will bring many benefits to local residents and businesses in both the Glenties and Ardara areas.

The Glenties supply is on the Environmental Protection Agency’s (EPA) Remedial Action List (RAL) for high levels of THMs and these works have been undertaken to reduce the risk posed by THMs for these customers.

The project, which is being carried out by Veolia Limited on behalf of Irish Water and in partnership with Donegal County Council, is scheduled to take approximately eight months to complete. It will ensure a better quality drinking water supply, reduce the risk of THM formation in the supply and the upgraded treatment plant will support economic and social development in the area.

Once the works are complete, tested and commissioned the plant will be in compliance with current Drinking Water Quality Regulations which is good news for the residents and businesses in the surrounding area.

Explaining further the scope of works involved, Irish Water’s Capital Programme Lead John McElwaine said: “These necessary upgrade works will be contained on site so there will be minimum disruption to local residents and businesses. The project is essential to ensure the plant has the necessary barriers in place against cryptosporidium and THM formation. Ultra violet treatment will be installed as part of this project as well as improvements to the chlorination process and the installation of a system called air-stripping to ensure THM compliance.”

Irish Water has put in place the first national THM plan and a prioritised programme of investment to address all inadequacies in drinking water parameters including THMs. By 2021 the utility plans to reduce the number of schemes on the RAL to zero with an investment of €327 million in upgrading water supplies at risk from THMs.

THMs, or trihalomethanes are chemicals formed by the reaction of naturally occurring dissolved organic material with chlorine which is used for disinfection in order to protect against pathogenic bacteria.

Irish Water spent over €526 million on water services in 2017. Capital investment in the region of €700 million per year is needed for a sustained period of several decades to address the poor condition of Ireland’s water infrastructure. Works have been prioritised to address the most critical issues in line with commitments outlined in Irish Water’s Business Plan up to 2021. Delivery of the business plan will involve a €5.5bn investment in capital spending on drinking water and wastewater quality and capacity and new infrastructure up to 2021 while achieving efficiencies of €1.6bn.
