NI Water is about to start a £300,000 programme of sewer improvement work in Derry’s Prehen area to enhance the local sewerage infrastructure and reduce the risk of out of sewer flooding in the area.
The sewer improvements, which will be mainly undertaken using trenchless techniques to minimise disruption, wil get underway next week in Prehen Park and will be extended to various areas of Prehen over a period of approximately 8 weeks.
Work at most locations should take no longer than 1-2 days to complete.
NI Water’s Robert McLean, Senior Project Manager explained: “This essential work will involve the repair of existing sewers using underground trenchless techniques where possible.
“This innovative approach will significantly reduce the duration of the works and disruption to the public. Where this method of repair is not possible, due to the condition of the sewer, ‘open-dig’ repairs will be carried out.
“The programme of sewer repairs for the Prehen area will also involve some work on private lands.
“NI Water through our project team, CivCo and AECOM, will liaise with any residents, businesses and landowners directly affected by these works. We appreciate that work of this nature can be disruptive and we will endeavour to keep disruption to a minimum.
“We would like to thank the public for their patience and cooperation as we complete this essential work. Local communities will benefit from these sewer improvements and reduced flood risk for many years to come.”
The work will be undertaken at various locations around Prehen and signage will be in place in the affected areas.
In order to safely undertake any work located on roads, it may be necessary to have short duration lane closures in place with two-way traffic maintained using temporary traffic controls where appropriate.
Vehicle access for residents and businesses will be maintained as far as possible but could be subject to slight delays, while pedestrian access will be available at all times.
Parking restrictions may be in place around working areas.
Where possible, the works will be undertaken during normal working hours, which will generally be 8 am to 6 pm.
However, depending on location, it may be necessary to undertake some of the work during the evening/night to reduce disruption to businesses and the public.
NI Water manages a network of 15,600km of sewers on a daily basis and we have invested billions in our water and wastewater infrastructure.
However, no amount of investment will completely stop blocked pipes or inappropriate items polluting our environment.
Items such as baby wipes and sanitary products are often the cause of out of sewer flooding which can easily be avoided by only flushing the 3Ps: pee, poo and toilet paper; everything else needs to go in the bin.
