The core requirement of the Greater Dublin Drainage project was to safely deliver a Regional Wastewater Treatment Plant and associated marine outfall located in the northern part of the Greater Dublin Area (GDA), and an Orbital Drainage System linking the Regional WWTP to the existing regional sewer network.

The Greater Dublin Drainage project proposed a new regional wastewater treatment facility to be located in the townland of Clonshaugh in North County Dublin, an underground orbital sewer from Blanchardstown to Clonshaugh, a new pumping station at Abbotsown, a partial diversion of the north fringe sewer, and an outfall pipeline to return the treated water to the Irish Sea. The project also included a regional sludge treatment centre at the new Greater Dublin Drainage facility and  an associated biosolids storage facility at Newtown near Kilshane Cross.

TOBIN Consulting Engineers was appointed as Project Engineering Consultant as part of the Greater Dublin Drainage project which has helped to:

  • safeguard public health
  • improve and protect the environment
  • facilitate employment, social progress & economic growth in the wider Dublin

The proposed project also facilitates the continued development of the Greater Dublin Area. There is the potential for socio-economic gains, including economic growth and residential development.
