RPS provided full civil, architectural, environmental, landscape design services, along with overall design co-ordination services on the €98.5m project for client Sisk Dragados Drace (SDD Joint Venture), who were appointed Design & Build Contractors to Dun Laoghaire-Rathdown County Council. The project involved the upgrading of the existing Shanganagh Wastewater Treatment Works to provide high level secondary treatment and the laying of a pipeline from Bray Pumping Station to the new Shanganagh plant to bring wastewater for treatment.
The Shanganagh Bray Waste Water Treatment Plant, one of the largest in Ireland, now has capacity to treat effluent from a 186,000 population equivalent and the potential to increase capacity to 248,000 in the future for a large conurbation from Foxrock/Carrickmines/Sandyford to the Dublin/Wicklow border, together with Bray, Co. Wicklow.
The project brings to an end the discharge of untreated wastewater into the Irish Sea and safeguards and protects water quality at Killiney Beach and Bray Strand to meet EU standards. It is a high performing, sustainable wastewater facility, representing ‘state of the art’ innovative technology in wastewater and sludge treatment, energy recovery and environmental management to standards which set new benchmarks for excellence for such plants in Ireland.
