Irish Water is progressing the Upper Liffey Valley Sewerage Scheme Contract 2A which includes the construction of a new interceptor sewer to connect Newbridge to the Osberstown Wastewater Treatment Plant.
Once the proposed project is complete it will facilitate increased flow to the existing Osberstown Wastewater Treatment Plant and support future population and economic growth in Newbridge.
The investment will also significantly reduce overflows to the River Liffey at Kilbelin and Newhall, ensure that wastewater is treated and discharged in compliance with the Urban Wastewater Treatment Regulations 2001, ensure compliance with conditions set out in the EPA’s Wastewater Discharge Licence and help Ireland avoid substantial EU penalties.
Irish Water has published a notice to confirm a Compulsory Purchase Order (CPO) has been granted to acquire the necessary lands in Kilbelin, Littleconnell, Halverstown, Greatconnell and Newhall for permanent way leaves, permanent right of way and temporary working areas for the project. Irish Water is progressing with a tender competition for a contractor and the works are expected to take approximately two years to complete.
The proposed project includes diverting the existing 675mm sewer at Kilbelin in South-East Newbridge to a new waste water pumping station and storm storage tank at Kilbelin. From the new pumping station there will be a new 500mm diameter rising main and 900mm diameter gravity sewer to a proposed new waste water pumping station and storm storage tank at Little Connell.
From the new pumping station at Little Connell, there will be a new 600mm diameter rising main and 900mm diameter gravity sewer to a new waste water pumping station and storm storage tank at Newhall. Construction of a 700mm diameter rising main from Newhall to Osberstown Wastewater Treatment Plant completes the project.
The project is needed as the current wastewater infrastructure is unable to support the needs of the area and it is not compliant with Urban Wastewater Treatment Regulations 2001 and conditions as set out in the EPA’s Wastewater Discharge Licence.
Commenting on the announcement, Paul Fallon, Wastewater Infrastructure Manager, at Irish Water said: “Irish Water is committed to investing in the wastewater treatment infrastructure in Kildare to support the needs of the growing population. The Upper Liffey Valley Sewerage Scheme (Contract 2A) will benefit the local community and the environment and will ensure that Ireland complies with the Urban Wastewater Treatment Regulations 2001 and conditions as set out in the EPA’s Wastewater Discharge Licence.”
Irish Water spent over €530 million on water services in 2016. Capital investment in the region of €700 million per year is needed for a sustained period of several decades to address the poor condition of Ireland’s water infrastructure.
Works have been prioritised to address the most critical issues in line with commitments outlined in Irish Water’s Business Plan up to 2021. Delivery of the business plan will involve a €5.5 billion investment in capital spending on drinking water and wastewater quality and capacity and new infrastructure up to 2021 while achieving efficiencies of €1.6 billion.
