In 2020/21 we are investing €4.9m to improve the Erne and Derg cross border river catchments that are a source of our drinking water, piloting changes in land management techniques such as fencing to exclude livestock and replacing boom spraying of the herbicide MCPA for rush control, with weed wipers, which helps to reduce the amount of herbicide running off into our rivers and streams. It is hoped these initiatives will help restore nature and improve the water quality before it reaches our works.
