Over 4 kilometres of troublesome water mains have been replaced in the Naran, Portnoo, Dungloe and Lettermacaward areas of Donegal to improve the Portnoo Water Supply.
Following an investment of over €970,000 by Irish Water, the project completed by JO Hearty Ltd. will reduce the risk posed by THMs. THMs, or trihalomethanes, are a harmful by-product of the chlorination process.
The works took place to reduce the risk of high levels of THMs in the water, which caused the supply to be placed on the Environmental Protection Agency’s (EPA) Remedial Action List (RAL).
The works included the installation and commissioning of over 4km of water main in the Naran and Portnoo, Dungloe and Lettermacaward areas of Donegal. Three kilometres of mains were replaced in Naran and Portnoo, 350m in Quay Road, Dungloe and 1km in Lettermacaward.
Customers supplied by the Portnoo Water Supply are now enjoying a better quality and more secure supply of water, according to Irish Water.
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.
