Next phase of Culmore Trunk Sewer improvements planned for Strand Road, Derry/Londonderry

16 October 2025 14:30

Our contractor, GRAHAM, is due to begin the next phase of relining works on the Culmore Trunk Sewer on Strand Road in November.

In advance of the relining works getting underway, some repairs to associated manholes in the area are required. This work will require a short overnight road closure and has been programmed to be undertaken next week, to help reduce disruption ahead of the city’s Halloween festivities

Explaining the programme of work, Robert McLean, NI Water Senior Project Manager said: 

“The next phase of relining work is scheduled to take place in the Strand Road area. In preparation for the relining works getting underway in early November, GRAHAM need to carry out some improvements to existing manholes in the area. These have been programmed for the week commencing 20th October ahead of the annual Halloween celebrations.

“To undertake the manhole works as safely as possible, Strand Road will be closed between Clarendon Street and Queens Quay Roundabout each night from Monday 20th between 7pm and 6am. During this time, traffic will be diverted along Lower Clarendon Street and Queens Quay.

“All traffic management will be removed from the area by Friday 24th October and will be reinstated at 7pm on Monday 3rd November to facilitate the specialist relining works. The relining element of the work will require the same closure on Strand Road, from Clarendon Street to Queens Quay Roundabout, each night between 7pm and 6am. The relining work should be completed within two weeks.”

“The work on Strand Road is part of a major programme of NI Water investment to upgrade the wastewater network serving the city, which has already seen over 1,100 metres of the Culmore Trunk Sewer relined between Foyle Road and Queens Quay. The relining works will strengthen the sewerage network to support future development in the city and help protect against sewer collapses, blockages and the risk of out-of-sewer flooding.

“The use of the specialist trenchless (underground) relining methods helps to accelerate progress and eliminates the need for large open-cut trenches which would require longer road closures. Night-time working is being employed to further reduce disruption. 

“NI Water and our contractor GRAHAM thank the public for their continued patience and cooperation as we continue with this programme of sewer improvements. The city will benefit from this scheme for many years to come.

“The project team appreciates the co-operation of the wider public in ensuring that children do not play in or around any site or machinery. Working areas will have warning signs in place to protect the public from any hazards. The public are advised 

to stay out of these working areas for their own safety as we work to complete the scheme.”
