As part of our application for development consent, we clearly identified the potential impacts of installing the replacement pipeline as part of the Environmental Impact Assessment process. This covered social, cultural and historical impacts, not only impact on the natural environment. We also conducted surveys to assess the engineering proposals for the pipeline, such as assessing potential access routes or ground conditions where trenchless installation techniques could be used.
Our final route for the replacement underground pipeline includes ‘Limits of Deviation’, which show the maximum area within which the pipeline could be installed. We are continuing to carry out surveys to help us determine the most suitable place to install the replacement pipeline within the Limits of Deviation. This will include surveys to help us better understand existing underground utilities and archaeological features in the area we are looking to install the pipeline.
