With effect from 1 January 2014, Irish Water has statutory responsibility for all aspects of water services planning, delivery and operation at national, regional and local levels including the delivery of water services capital infrastructure, while the local authorities remain responsible for supervising the group water sector.
Based on current available data, Irish Water estimates that lead pipework exists in approximately 180,000 residential properties in Ireland. While there are no lead water mains in Ireland, service connections within properties can contain traces of lead. The vast majority of lead pipes are contained within properties built up to and including the 1970s.
The Government published a National Strategy to Reduce Exposure to Lead in Drinking Water in June 2015. In response to the recommendations of this strategy, Irish Water prepared a detailed Lead in Drinking Water Mitigation Plan to identify measures to mitigate the risks to human health posed by the presence of lead in drinking water. Irish Water has indicated that it will remove all lead in public supply pipes over the next ten years. They have also put in place an interim water treatment programme to protect consumers from lead exposure while this replacement programme is implemented.
Irish Water is responsible for the service pipe up to the property boundary; however, most lead pipes are within the property boundary and are the responsibility of the property owner. My Department has introduced a grant scheme to assist owners of premises connected to a domestic water supply with the costs of replacing lead piping or related fittings located within the internal distribution system of the premises, as defined in the Water Services Act 2007. The grant is administered by local authorities and information on how to apply for this grant is available on my Department’s website at the following link: https://www.housing.gov.ie/sites/default/files/publications/files/leaflet_-_grant_to_replace_lead_pipes_and_fittings.pdf
