Portlaw Water Main Replacement - Factory Road

Uisce Éireann, in partnership with Waterford City & County Council, is replacing ageing water mains on Factory Road, Portlaw, Co Waterford to provide a more reliable water supply, improve water quality and reduce high levels of leakage.

The programme to replace the water mains on Factory Road, Portlaw, Co Waterford will commence on 22 May 2019. These works are being carried out as part of Uisce Éireann's National Leakage Reduction Programme. The works have been designed to alleviate water quality issues that have resulted in 'Boil Water Notices' for a small number of residents and businesses along Factory Road.

Uisce Éireann would like to remind residents and businesses along Factory Road in Portlaw, that the Boil Water Notice remains in place for 3 water supply connections until further notice. The restriction on the supply is implemented following consultation with the Health Service Executive (HSE) in order to protect public health due to sustained iron exceedances and low residual chlorine. The works will be carried out on behalf of Uisce Éireann by Coffey Northumbrian Ltd. and are expected to be completed by mid June 2019.

  • A Reliable Water Supply - Replacement of aged 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
  • Improved water quality - Replacing existing old cast iron and lead from the public water network with new modern pipes will reduce the risk of contamination and discolouration to the water supply
  • Following commissioning and testing of the works, consideration to lifting the restriction will be carried out in consultation with, and on the advice of, the HSE with whom Uisce Éireann is liaising on an ongoing basis
  • 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 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 300 metres of old cast iron water mains with 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
