Castleblayney Water Main Replacement - Main Street

National Leakage Reduction Programme

Uisce Éireann, in partnership with Monaghan County Council, is replacing ageing water mains on Main Street, Castleblayney to improve security of supply, improve water quality and reduce high levels of leakage.

The programme to replace problematic water mains on Main Street is scheduled to commence when the Muckno Street works are complete in early 2019. These works are being carried out as part of Uisce Éireann's national Leakage Reduction Programme. The section of works will take place along both sides of Main Street including a loop around the court house within Castleblayney Town centre. The works will be carried out on behalf of Uisce Éireann by Farrans Construction Ltd. and are expected to be completed in June 2019.

​A Reliable Water Supply

  • Replacement of water mains and service connections will reduce the instances of bursts and water outages and will ensure a reliable supply of water to customers and local businesses in the area

Reduced Leaks

  • Replacement of water mains and service connections will eliminate existing leaks and reduce the amount of clean drinking water lost into the ground

Improved Water Quality

  • Removing existing old cast iron and lead from the public water network and replacing them with new plastic pipes will reduce the risk of contamination

Improved Operation and Maintenance

  • These works will deliver cost savings by providing improved water network operation that will require less maintenance in the future


  • The works involve the replacement of approximately 1,150 metres of problematic water mains with new high density polyethylene (plastic) pipes
  • The works will also involve laying new water service connections from the public water main in the road to customers' property boundaries and connecting it to the customers' water supply
  • Where the existing service connections on the public side are lead these will also be replaced as part of this improvement work
