Irish Water to upgrade Dublin City’s Victorian sewer network


Water utility firm Irish Water is working in collaboration with Dublin City Council to upgrade several old brick lined sewers in Dublin City Centre.

The investment will see that the impacted city streets no longer stand at risk of sewer collapse and flooding which could have a really negative impact on local businesses and residents.

One project includes the upgrading of Victorian sewers in Parnell Street, Marlborough Street, Gardiner Street, North Great Georges Street and Hill Street.

Separate projects were completed earlier this year on Townsend Street and Pearse Street and a project is progressing for Killarney Street with a combined investment of €450,000.

Work on a €550,000 investment in the Parnell Street area has been completed. This sewer rehabilitation involved the relining of the sewers extending from Marlborough Street to Gardiner Street, including sections of Parnell Street, North Great Georges Street and Hill Street.

The Victorian brick lined egg shaped sewers need to be upgraded and were lined with a reinforced plastic liner which strengthened the sewers and removed the potential of sewer collapses and possible city centre flooding.

To commence work on the Killarney Street project, a contractor has been appointed. Site investigation and survey work will be completed in November.

Complete relining of the sewer will commence in Q1 of 2017.

Irish Water programmes specialist for the East and Midlands Region Ivan Corcoran said: “Dublin City’s sewer network dates back to Victorian times, Irish Water is investing in the network to repair any damage to the sewers. The investment in the sewer network ensures that Dublin City has a robust network and the work prevents any potential flooding on key City streets.

"Irish Water is making real and significant progress addressing the most serious deficiencies in Ireland’s wastewater infrastructure in Dublin City and across the country. The investment in the sewer network in Dublin City ensures that the network has the capacity to support the economic development and growth of the City.”

Irish Water will invest €532m on water services in 2016 to bolster the country’s water and wastewater infrastructure.

Capital investment in the region of €700m every year is required for a sustained period of several decades to address the poor condition of Ireland’s water infrastructure.

Works have been prioritised to address critical issues in sync with commitments outlined in Irish Water’s Business Plan up to 2021.

Delivery of the business plan will involve a €5.5bn investment in capital spending on drinking water and wastewater quality and capacity and new infrastructure up to 2021 while achieving efficiencies of €1.6bn.
