18 August 2023 10:06

NI Water is planning to undertake essential Sewer Improvement Work on the existing sewerage system in the Church Street and Water Street areas of Rostrevor, as part of an overall programme of work to improve the existing sewers in Rostrevor. These essential repairs will involve the construction of new and the replacement of existing manholes and sewers.

The work is planned to get underway during the week commencing 21st August 2023 and will last approximately 4 weeks.

As part of the upgrade, repairs to the existing sewers will take place on the road from No. 4 Water Street across to No. 34 Church Street. To facilitate the work in the safest possible manner, the following measures will need to be implemented on Water Street and Church Street:

  • Water Street:  Monday 21st August – Friday 1st September - Water Street will be continuously closed to through traffic between Church Street and Bridge Street. Working hours will be 7.30am to 6pm. The working area will extend from No. 4 Water Street to the junction with Church Street. Access for residents and businesses will be via Church Street and Bridge Street but may be subject to delay. For safety reasons traffic will not be permitted through the working area.  

  • Church Street: 9.30am Monday 21st August – 4.00pm Friday 1st September –a continuous lane closure will be implemented on Church Street for 2 weeks at the junction with Water Street. Temporary traffic lights will be in place during this time to manage traffic flow.

  • Church Street: Monday 4th September – Friday 15th September – a lane closure will be implemented on Church Street between the hours of 9:30am and 4.00pm each day. Temporary traffic lights will be in place only during this time to manage traffic flow.

NI Water and our contractor AG Wilson would like to thank the public for their patience and cooperation while we undertake this essential work and aim to complete the work as quickly as possible with minimal disruption. This upgrade will improve the condition of the existing sewerage system, reducing the likelihood of sewer collapses, blockages and out-of-sewer flooding.

The team would also like to take this opportunity to highlight that construction sites are dangerous areas for unauthorised persons, especially children. Working areas will have warning signs and traffic management in place to protect the public from any danger.
