Construction Work Officially Underway on Irish Water Saggart Reservoir Development

Representatives from Irish Water along with those from Dublin City Council and South Dublin County Council and Coffey officially turned the sod to mark commencement of work on the Saggart Reservoir project in Co. Dublin last Thursday afternoon. Coffey is the main contractor on this strategically important project which will help secure supply of drinking water to homes and businesses in the Greater Dublin Area for the foreseeable future.

The Saggart Reservoir project involves the construction of a new state-of-the-art covered treated storage reservoir that will be supplied from Ireland’s largest water treatment plant at Ballymore Eustace. When completed, the new reservoir will have the capacity to store 100 million litres of treated drinking water which is the equivalent of 40 Olympic sized swimming pools. Coffey has been appointed as the main contractor for the construction of the reservoir and its associate pipelines and the project is expected to be completed within 3 years.

Speaking at the sod turning, Deputy Lord Mayor of Dublin, Cllr Joe Costello said, “Turning the sod on the Saggart Reservoir project is an important milestone in the Greater Dublin Area’s water supply. The existing Saggart waterworks, built in the 1950s served our communities well and today marks the start of the construction of a new flagship reservoir that will serve homes and businesses across the GDA for decades to come. The reservoir will provide strategic water storage for the area and will provide for social and economic growth. I would like to commend those involved in bringing the project to this important day and I would like to wish the project team well as the build the flagship reservoir.”

Speaking at the sod turning for the Saggart reservoir project, Mayor of South Dublin County Council, Cllr Peter Kavanagh said, “The construction of this key piece of infrastructure demonstrates how Irish Water, working in partnership with South Dublin County Council and Dublin City Council and along with Coffey is delivering infrastructure that is critical for our communities and our economy. The delivery of this project will support existing and future residential and commercial development in the Greater Dublin Area and I would like to wish Irish Water and the project team well as they embark on this important project that will help to build resilience in our water infrastructure for the longer term” 

Stephen Seymour, Irish Water said, “This project announcement coincides with Irish Water asking the public to conserve water, it goes to show how these projects are essential to allow Irish Water to support social and economic growth in Ireland through the delivery of essential water and wastewater services. The size and scale of the task to improve water services for a modern growing economy shouldn’t be underestimated. We have made significant progress but there is work still to do as we continue to build world class water infrastructure through our multi-billion programme of investment. This particular project will provide strategic treated water storage capability at Saggart which is needed to support the building of houses and schools; to attract new industry and to allow companies to expand and grow across the GDA. In terms of size and scale, the new reservoir can store enough water to supply almost 300,000 homes with the water they need for one day. It is one of a portfolio of water projects that we are delivering to safeguard the water supply to homes and businesses.”
