Irish Water announce flagship project for the Greater Dublin Area with building of new reservoir

16 February 2021

Irish Water in partnership with Dublin City Council and South Dublin County Council is progressing with the building of a new reservoir in Saggart. This essential project involves the construction of a new 100 million litre covered treated storage reservoir that will help to safeguard the water supply to homes and businesses in the Greater Dublin Area (GDA). The new state of the art reservoir will store 100 million litres of treated drinking water, the equivalent of 40 Olympic sized swimming pools supplied from Ballymore Eustace Water treatment plant, Ireland’s largest water treatment plant.

The construction of the new reservoir and associate pipelines will start in March and is expected to be completed within 3 years. Coffey Construction Ireland Limited recently signed the contract to deliver this project on behalf of Irish Water.

The upgrade marks the first significant investment in the existing Saggart waterworks since it was built in the 1950’s. The current waterworks will be replaced with a new reservoir that will provide treated drinking water storage building resilience in the water infrastructure for the GDA and improving the security of supply for existing and future residential and commercial development.

Speaking about the Saggart reservoir project, Minister for Housing, Local Government and Heritage Darragh O’Brien said, “The construction of this key piece of infrastructure demonstrates how Irish Water, working in partnership with Dublin City Council and South Dublin County Council, 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 is one of a portfolio of water projects being delivered by Irish Water.” 

Brian Sheehan, Head of Asset Delivery, Irish Water said, “Irish Water is working 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."

Irish Water is adhering to government and HSE guidance and in compliance with stringent Covid-19 controls to deliver this essential project. For further information regarding this project please visit our Saggart Reservoir Project page.
