Irish Water marked the start of construction on one of the largest projects to upgrade the drinking water supply in South Dublin and North Wicklow.
When completed, the project will provide a more reliable water supply for existing homes and businesses while also providing additional capacity for future growth of up to 12,000 homes.
The project, known locally as the Old Connaught-Woodbrook Water Supply Scheme, will involve the construction of of two new state-of-the-art reservoirs and more than 13km of new water mains, providing new drinking water infrastructure for the area.
It will also will provide network resilience and flexibility for the Greater Dublin Area.
The project is expected to be completed by the end of 2024.
