Glasnevin Water Mains Replacement

National Leakage Reduction Programme

Replacement of ageing cast iron water mains in Drumcondra and Glasnevin, Dublin 9 to reduce leakage and ensure a safer and more secure water supply to customers.

Irish Water, working in partnership with Dublin City Council, will soon begin works to replace ageing cast iron water mains in Drumcondra and Glasnevin, Dublin 9. The works are planned to commence on 11 June 2018. These water mains renewal works are being carried out as part of Irish Water’s national Leakage Reduction Programme.

What is involved?

The water mains renewal works will involve the decommissioning and replacement of over 3.2 kilometres of old and damaged cast iron water mains most of which is in place since the early 1900’s. The locations to benefit from these improvement works in Drumcondra and Glasnevin are:


Marguerite Road Crescent Villas Gartan Avenue Saint Ignatius Road
Hollybank Road Iona Park Lindsay Road Innisfallen Parade
Iona Crescent Iona Road Whitworth Place Glengarriff Parade
Iona Villas


The 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 as part of the improvement works.

These works will be carried out by GMC Utilities Group in partnership with Dublin City Council on behalf of Irish Water. The construction works will commence on the 11th June 2018 and are expected to take approximately 7 weeks to complete.

Leakage Reduction


​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

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

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

Affects of works

  • Areas of work will be limited to short sections to minimise impact on customers. The works may involve some short-term water shut offs and the project team will ensure that customers are given a minimum of 48 hours notice prior to any planned water shut offs.
  • Traffic management may be in place during this time. Local and emergency traffic will be maintained at all times.
  • We understand that this type of work can be inconvenient and works crews will make every effort to minimise any disruption these necessary works cause.
