NI Water to commence Sewer Upgrades in Main Street, Dundrum

12 February 2019 12:05

NI Water will shortly commence work on this major programme to upgrade the sewerage infrastructure in the Main Street area of Dundrum. This work, which represents an overall investment of £4.2M, will include the upgrade of sewers and replacement of two existing Wastewater Pumping Stations and will be undertaken in a number of phases over the next 2-3 years.

The first phase of work will commence on Monday 18th February and continue until Friday 3rd May 2019. This will involve the installation of 2km of new sewers between the existing Dundrum Waste Water Treatment works on the Newcastle Road and School Road. 

Detailed traffic management arrangements have been discussed with the Department for Infrastructure. In order for the works to be carried out safely, it will be necessary to have a lane closure in place on Main Street for the duration of the works; two-way traffic flow will be maintained with the use of temporary traffic signals. Parking restrictions will also be in place around the working area.

As with all major construction works of this nature, some level of disruption and delays should be expected, however, we will endeavor to minimise this as much as possible.

In order to expedite progress, normal working hours will be 7am to 7pm Monday to Friday, and 7am to 1pm on Saturday. However, it may be necessary at times for work to be undertaken outside of these hours.

NI Water and our contractor BSG Civil Engineering would like to thank the public in advance for your patience and cooperation whilst we prepare to commence this essential improvement work. We assure you that we will do everything that we can to keep all future disruption to a minimum.

Once all phases of the project are complete, the risk of out of sewer flooding and environmental pollution in this part of the sewerage network during periods of heavy rainfall will be significantly reduced.
