Vital project will remove lead connections and replace old fire hydrants

Irish Water is working in partnership with Dún Laoghaire-Rathdown County Council to replace 785 metres of ageing water mains on Monkstown Road in Co Dublin. The €275,000 investment will replace the approximately 140 year old water main which is prone to frequent bursts. The works are planned to begin on Monday, 2 October. They will be carried out by Córas Pipeline Services Limited on behalf of Irish Water. Initially works had started last March but were suspended due to protesters on Monkstown Road.  It is vital that this old water main is replaced to provide a secure water supply for customers.

This project will replace the ageing cast iron water main on Monkstown Road with a modern high density polyethylene (HDPE) plastic pipe. Due to the age of the network, dating from approximately 1870, there is a possibility that the pipes connecting the houses on Monkstown Road to the main are lead. Any lead pipes found on the public side will be replaced as far as the property boundary. The project also includes upgrading the existing fire hydrants on Monkstown Road to meet the current fire regulation standards.

The water main replacement works will take approximately 8 weeks to complete. In the event of a planned water shut off, residents and businesses will be notified two days advance of any disruption to their water supply. 

In order to minimise disruption, works will be carried out (Monday – Friday) during the following times (outside of peak traffic):

  • 9:30am to 4:00pm
  • 7:30pm to 9:00pm*

* The Contractor has advised that late evening works will be the exception rather than the rule. Late evening work could, on rare occasions, extend until 11pm. This is in keeping with the Contractor’s Road Opening License granted by Dún Laoghaire-Rathdown County Council.

The works will involve the partial closure of Monkstown Road. Only a single traffic lane will be operational with a stop/go system for the duration of the works. Side roads and entrances to properties off Monkstown Road will also be affected by the partial road closure, residents will be provided with access at all times. In order to minimise disruption to traffic, the road surface will be temporary reinstated as the works progress. Dún Laoghaire-Rathdown County Council is planning to resurface the entire Monkstown road in 2018.

Commenting on the project, Ivan Corcoran, Capital Programme Lead with Irish Water, said “It is vital that this ageing water main is replaced. The water main dates back to approximately 1870 and customers in the area have been impacted by frequent water outages. The new water main will secure the water supply for customers and provide them with a reliable water service.  During the project the fire hydrants along Monkstown Road will be replaced as they currently don’t meet fire regulation standards. The replacement of the fire hydrants will ensure that the emergency services will have access to equipment that meets the correct standards should an emergency arise. Replacing lead service connections will also be carried out which is part of Irish Water’s ongoing commitment to remove lead services to the boundary of properties. ”
