We have provided below a description of some current capital projects ongoing in Gas Networks Ireland and Irish Water. The monetary figure provided for each project represents the CER (Commission for Energy Regulation) approved project cost.
Gas Networks Ireland
Cluden to Brighouse Bay (€98m)
This project consists of the twinning the Southwest Scotland Onshore System between Cluden and Brighouse Bay in the UK, which will reinforce the 50 km single section of the SWSOS transmission system. GNI, facilitated by DCENR and the Scottish Executive, made a submission to the EU in Q2 2014 seeking part funding for the project as part of the EU’s Project of Common Interest (PCI) listing. In December 2014 the project was provisionally awarded €33.7m which represents the maximum amount that the project can receive. This pipeline will enhance security of supply and increase network capacity to meet growth in peak gas demand.
Nenagh Multi-Utility Programme (€17.2 m)
The Nenagh Multi-Utility Programme combines the development of a new gas network to the town, the rehabilitation of the existing water main network and the upgrading of the existing wastewater network into a single project. This initiative is made possible by the large overlap which exists between gas/water/wastewater networks with respect to geographical location and the fact that the two relevant network operators, Gas Networks Ireland and Irish Water, share a common parent company in Ervia. There are significant benefits arising from the multi-utility approach to this project, including reduced construction costs, reduced disruption to customers and the general public, faster overall project delivery.
Wexford (New Town Connection) Programme (€16.3m)
The programme is to provide a gas supply to both commercial and domestic customers in Wexford town. This is achieved by the construction of approximately 40 km of feeder main pipeline from a newly constructed AGI at Fisherstown to Wexford town. The town distribution network will consist of 34km of pipelines in and around Wexford town.
Upper Liffey Valley Sewerage Scheme Phase 3 Osberstown WwTP Upgrade (31.6m)
The Upper Liffey Valley Regional Sewerage Scheme Extension to the Osberstown Waste Water Treatment Plant will upgrade and expand the existing plant to provide a process which is in line with modern practice and compliant with current legislation and sustainability principles. The works will provide for the:
- Upgrade of the plant from 80,000 PE to 130,000 PE.
- Expansion of the preliminary and primary treatment processes.
- Conversion of the plant from a batch treatment process to a continuous flow process.
- Upgrading of the nitrogen, denitrification and biological phosphorous removal processes.
- Addition of a tertiary treatment process.
- Expansion of Sludge facilities.
Full treatment capacity of 130,000 PE is programmed to be delivered by the end of 2016.
Waterford Grouped Towns & Villages Sewerage Scheme1 Contract 8 (WwTPs - DBO) (€24m)
The Waterford Grouped Towns and Villages WWTPs project provides for the construction of waste water treatment facilities at towns and villages across County Waterford including Ardmore, Dunmore East, Cappoquin, Kilmacthomas, Stradbally, Tallow and Kilmeaden/Ballyduff.
The project includes for the construction of seven new wastewater treatment plants on green field sites, one at each location. A common treatment plant will serve the villages of Ballyduff and Kilmeaden. Each waste water treatment plant will include primary and secondary treatment processes such that the treated waste water will comply with the standards required to meet water quality objectives in the receiving waters at each location. Projected completion date for the full project is Q3 2016.
Swords WwTP Expansion (€22m)
The purpose of this project is to expand and upgrade the existing Swords WWTP from a design capacity of 60,000PE to a capacity of 90,000PE. The project will achieve this by introducing a new 40,000PE treatment stream, downgrading the existing treatment streams from 60,000PE to 50,000PE and introduce new tertiary treatment on all effluent. This will lead to improved discharge standards for final effluent outfalling to the Broadmeadow Estuary and includes UV treatment leading to reduced bacteriological levels in the discharge. The upgrade is expected to be complete in Q3 2016.
