Irish Water Strategic Infrastructure Development Planning Application to An Bord Pleanála – Greater Dublin Drainage Project

Irish Water Strategic Infrastructure Development Planning Application to An Bord Pleanála – Greater Dublin Drainage Project

 

(A Proposed Wastewater Treatment Plant, Orbital Sewer, Outfall Pipeline, Sludge Hub Storage Centre and Regional Biosolids Storage Facility) 

County Fingal & Dublin City

 

The Greater Dublin Drainage planning application proposes a new regional wastewater treatment facility to be located in the townland of Clonshaugh, 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.

 

The proposed development will be located within County Fingal and with a 60m section of pipeline in Dublin City and is approximately 25km long and consists of the following principal elements.
