Irish Water in partnership with Fingal County Council, will carry out site investigation work in Balbriggan and Howth over the coming weeks. The site investigation work will enable Irish Water, to fully assess the water infrastructure in Balbriggan and Howth and help it understand the design requirements needed to construct, 5.7km of new water mains for Balbriggan and 6.2kms of water mains and the provision of extra water storage capacity for Howth. Irish Water will invest €4.8 million in the new water mains for Balbriggan and a further €4.7 million in Howth. Construction of the new water mains are expected to commence in quarter one of 2018 and are expected to last for 18 months. This investment will improve the water pressure to homes and businesses and improve the security of the water supplies to these two communities. 

Balbriggan water supply is currently served by two water sources, one source is from the Leixlip Water Treatment Works via reservoirs at Ballycoolen, Swords and Jordanstown and the other source is from the Bog of the Ring Water Treatment Works. The investment in a new water mains for Balbriggan will address and resolve a number of supply issues including the inadequate capacity of the primary pipelines from Jordanstown reservoir to Balbriggan, reduce the reliance on the Bog of the Ring groundwater source, reduce the reliance on pumped water in the Balbriggan area and increase the security of supply to Balbriggan which results due to the location of the town at the northern extremity of the Dublin regional supply network system. The new water mains will also ensure that the water supply to Balbriggan meets the requirements during peak demand periods.

The construction of new water mains in Howth will improve the water pressure to Corr Bridge and Strand Road pumping stations, increase storage capacity and improve the water quality in the area. The scheme will involve the construction of 6.2km of a new 400mm trunk water main. Extra storage capacity will be provided for at Dungriffen Reservoir with the construction of a new 2600m3 reservoir and chlorination system. A new pumping station will also be constructed at the Dungriffen Reservoir.

To progress both the the projects for Balbriggan and Howth, site investigation work is due to commence in March 2016. The site investigation works will involve small trial hole excavations and borehole drilling to confirm the ground conditions in the area and identify the location of the existing utility services. During this phase of the project, Irish Water will endeavour to keep traffic disruption to a minimum and will provide advance notice on any major road closures that maybe required.

In Balbriggan the site investigation work will be carried out on the R132 from Jordanstown through Balrothery Village to Tanners Water Lane and at the junction with the R132 and Castlelands and at the roundabout close to the St Peter and Pauls Church and will last for a 12 week period.

In Howth the site investigation work will be carried out in the following areas and will also last for a 12 week period.

Commenting on the investment in Balbriggan and Howth, William McKnight, Water Treatment Programme Regional Lead said “Irish Water is carrying out these site investigation works to understand the requirements to construct 6.2kms of new water mains and the provision of extra storage capacity for Howth and 5.7km of new water mains in Balbriggan. Irish Water will invest a total of €9.5 million to upgrade the water infrastructure in Balbriggan and Howth. This investment is vital to ensure that homes and business in the two areas have a more reliable water supply. The site investigation work is the first phase of these projects and will enable Irish Water to confirm the condition and location of the existing water mains. Providing a safe and secure water supply to these two communities is a key objective for Irish Water”.

Irish Water invested €340 million in improving water and wastewater services in 2014 and over €363 million during 2015. Irish Water plans to spend €532 million on water services in 2016. Capital investment in the region of €700 million per year is required for a sustained period of several decades to address the acknowledged deficiencies in the country’s water infrastructure. Works have been prioritised to address the most critical issues in line with commitments outlined in Irish Water’s recently published Business Plan. Delivery of the Business Plan will involve a €5.5bn investment in capital spending on drinking water and wastewater quality and capacity and new infrastructure up to 2021.
