Cabra Water Main Replacement

National Leakage Reduction Programme

Uisce Éireann replacing ageing cast iron water mains in Cabra, Dublin 7 to improve security of supply and quality for local customers and businesses and reduce high levels of leakage.

Uisce Éireann, working in partnership with Dublin City Council, will begin works to replace ageing water mains in Cabra, Dublin 7. The works will begin with area surveys this coming week followed by construction in early summer 2018. These water main renewal works are being carried out as part of Uisce Éireann’s national Leakage Reduction Programme.

The Leakage Reduction Programme will see over €500 million invested over four years to reduce leakage and remove problematic pipes from the public water network. These works will help to ensure that we have a clean, safe and reliable water supply now and into the future to support our growing population and economy.

Leakage Reduction


  • Works will involve the decommissioning and replacement of 5.7 kilometres of old and damaged cast iron water mains
  • Existing pipes will be replaced with new modern high density polyethylene (plastic) pipes
  • The works will also involve laying new water service connections from the public water main in the street to customers’ property boundaries and connecting it to the customers’ water supply
  • Where there is lead on the public side of the service connection this will be removed
  • Construction works commencing in summer 2018 will move from location to location and in total across all areas are expected to take approximately 12 weeks to complete
