Irish Water is investing €5.5 million in a water mains rehabilitation programme across Co. Carlow which will result in significant improvements in network performance, security of supply and efficiency. 

The Carlow Water Mains Rehabilitation Project will involve the rehabilitation and replacement of approximately 14km of aging water mains with new heavy duty polyethylene (heavy duty plastic) pipes and the replacement of approximately 1,200 water service connections in Carlow Town, Tullow, Bagenalstown and Tinnahinch.

Welcoming the announcement, Mark O’Duffy, Water Networks and Rehabilitation Programmes Regional Lead, Irish Water said: “Upgrading Co. Carlow’s water infrastructure and the replacement of many older pipes will result in significant benefits for residents and businesses across Co. Carlow providing a more secure, robust water supply and reducing leakage in the network. Over the coming months the project team will be undertaking site investigation and surveying work in order to assist in the design of the water network upgrade. We’ll make every effort to keep disruption to a minimum and people in each area will be notified in advance of the works commencing.”

The site investigation works will begin in August in Bagenalstown and Tinnahinch, before moving on to Tullow and Carlow town. Irish Water expects these works to take approximately twelve weeks. The work will be carried out by IGSL Ground Investigation and Geotechnical Specialists working on behalf of Irish Water.  Following this initial work, it is envisaged that construction will commence in mid-2017 and the project will be complete within twelve months.

Site investigation works will involve small trial hole excavations and borehole drilling in the public roadway in order to confirm ground conditions and identify the location of the existing utility services so the route of the new water mains can be designed. This work will also assist in the identification of any archaeological sites of interest. Traffic management measures will be put in place and local access will be maintained at all times, however the works will lead to some disruption. It is not anticipated that this will involve any interruption to water supply. Any road closures required will be advertised in advance in the local press.

Surveying work will be undertaken at the same time as the site investigation works in towns, with the surveys being carried out by Ryan Hanley Consulting Engineers working on behalf of Irish Water. Irish Water is working in partnership with Carlow County Council to deliver this important infrastructure project across the county.
