Example of an old cast iron pipe that we are replacing

Tackling the high levels of water leakage

Works are commencing this week in Graiguecullen to improve the water supply for residents and businesses by tackling the high levels of water leakage in the area. Irish Water, working in partnership with Carlow County Council is replacing over 4 kilometres of old cast iron back yard water mains and constructing 2.5 kilometres of new water mains along the public road.

The old, damaged pipes will be replaced with modern, high density polyethylene (plastic) pipes. New service connections will be installed from the new water main to each customer’s property. Works starting this week will replace 700m of back yard cast iron water mains in the Maryborough Street, Chapel Street, Church Street, The Numbers and Henry Street areas.

Replacement of a further 3.6 kilometres of cast iron water mains

Irish Water’s Leakage Reduction Programme will continue in Graiguecullen later this year and into 2019, when a further 3.6 kilometres of cast iron water mains will be replaced in the Governey Park, Maher Road, Staunton Avenue, Whitney Place, St Clare’s Road, Croppy Place, Colclough Avenue, Derrig Avenue, St Fiacc’s Terrace, Sleaty Street, Pearse Road, Duggan Avenue and Pacelli Avenue areas.

These works will be carried out by Coffey Northumbrian Ltd in partnership with Carlow County Council on behalf of Irish Water.

“As they get older, cast iron watermains can become severely corroded and have a high level of leakage as well as being subject to frequent bursts, which in turn leads to water discoloration. At present, it is estimated that some three-quarters of the water supplied to Graiguecullen is lost to leaks in the network.” said Mark O’Duffy, Network Programme Regional Lead at Irish Water.

“We would like to thank local residents and businesses for attending our Information Evening in August and for their ongoing cooperation as we work together to deliver these improvements for Graiguecullen; and Carlow County Council for their continuing efforts in delivering this challenging programme of works.”
Customers to benefit from these improvement works will be contacted directly by Coffey Northumbrian Ltd. to assess their current water connection arrangement and discuss the best way to connect the new service. 

“We will continue to work with the community to minimise disruption. Customers can phone Irish Water on Callsave 1850 278 278 if they have any further questions about the project,” added Mark O’Duffy
