Irish Water welcomes oral hearing for Greater Dublin Drainage Project
New wastewater treatment facility to serve the growing population of the north Dublin area
Irish Water welcomes the opportunity to explain the environmental, technical, economic and public health benefits of its proposed Greater Dublin Drainage (GDD) Project at an oral hearing of An Bord Pleanála in Dublin today. The GDD Project is a vital development to protect public health, safeguard the environment and support the sustainable social and economic growth of the greater Dublin area into the future.
Growing population to almost double wastewater in 30 years
The greater Dublin region is projected to increase by almost half a million people and produce almost double the current volume of wastewater over the next 30 years. The GDD Project proposes to develop a new regional wastewater treatment facility and associated drainage infrastructure to serve this growing population.
An Bord Pleanála is commencing an oral hearing at the Gresham Hotel, O’Connell Street, Dublin today, as part of its statutory consultation and assessment of the GDD Project planning application. The hearing is scheduled to last seven days.
Oral hearing to allow further discussion and examination of issues
In June 2018, we made an application for strategic infrastructure development for the GDD project to An Bord Pleanála. There followed periods of statutory public consultation by An Bord Pleanála. The purpose of the oral hearing is to allow further discussion and examination of relevant issues by the parties to the application.
Irish Water, GDD Project Manager, Jane Chambers:
“Greater Dublin Drainage is a once-in-a-generation project to ensure that the wastewater generated every day in our homes, schools and workplaces will continue to be treated safely in compliance with the EU and national wastewater treatment regulations. Having adequate wastewater treatment infrastructure is essential to facilitate housing provision and commercial development and to support the sustainable growth of the north Dublin area."
“The new regional facility, as proposed, is the most environmentally, technically and economically beneficial solution to meeting north Dublin’s long-term wastewater treatment needs. Irish Water welcomes this further opportunity to discuss this essential wastewater project with An Bord Pleanála and with all stakeholders over the coming days.”
The GDD planning application proposes a new regional wastewater treatment facility to be located in the townland of Clonshaugh in north Dublin, an underground orbital sewer from Blanchardstown to Clonshaugh (to intercept existing flows to Ringsend), a new pumping station at Abbotsown, and an outfall pipeline to return the treated water to the Irish Sea. The project also includes a regional sludge treatment centre at the new GDD facility and an associated biosolids storage facility at Newtown near Kilshane Cross.
Infrastructure to be operational from 2026
Subject to planning consent, it is intended that Dublin’s regional wastewater treatment facility and associated infrastructure will become operational from 2026 and will provide wastewater treatment capacity for the equivalent of half a million people into the future.
