Sewer Rehabilitation Programme Continues - Inner Walls Public Realm Sewers, L’Derry

30 January 2017 17:21

NI Water is currently continuing work on this sewer improvement project within Derry City Walls. Work will commence on Bishop Street Within on Monday 30th January 2017 and we anticipate this work will take approximately 3 weeks to complete.

Extensive investigation works, which were carried out during November 2016, identified that the sewer in Bishop Street Within is in very poor condition. Therefore, it is necessary to relay this section of sewer as soon as possible. All of these works are being programmed to be completed prior to the commencement of Public Realm work within the Walls later this year.

This section of work was initially planned to be undertaken during daytime hours, however due to restrictions caused by the number of existing services, this sewer now needs to be replaced along the original line and will necessitate night time work.

Detailed traffic management arrangements have been discussed with TransportNI and the work has been programmed during evening/night time hours which will also minimise disruption to businesses, road users and the public.
In order to carry out the work safely, it will be necessary to have a temporary road closure in place during night-time hours and a diversion route will be clearly signposted. There will be some parking restrictions in the vicinity of the works. Vehicular access will be maintained for residents where possible and pedestrian access will be maintained at all times.
The works will be carried out Monday – Thursday nights between 7pm and 7am, with all traffic restrictions being removed prior to 7am.We will do everything within our means to keep noise levels to a minimum during the late evening and night-time work, and where possible will carry out the most disruptive work prior to 11pm.

As far as possible, we will continue to plan the work to avoid clashing with major events in the City. NI Water and our contractor will continue to liaise with the City Centre Initiative to coordinate the work at different locations. We will also liaise with businesses within the area to facilitate access for deliveries etc.

NI Water and our contractor Quinn Automatic Ltd would like to thank the public for their ongoing patience and co-operation while this essential work is completed. We will do everything we can to keep disruption to a minimum and ensure the work is completed as soon as practicably possible.
