The work includes fencing the working area (the ‘spread’), removing and storing topsoil, and digging a trench, which will then be backfilled once the pipeline has been laid. The new pipeline is expected to be in operation by the Autumn, although reinstatement of the land may continue after this time.

The company said that the pipeline will meet the growing demand for reliable and economic gas supplies in the South West of England by next winter.

National Grid has been working with the Gloucestershire County Council Rights of Way team, and local walkers to ensure the majority of footpaths and bridleways that cross the pipeline construction area will remain open throughout the work, with stiles or kissing gates being installed at crossing points to allow access. Where rights of way cannot be kept open, short diversions are provided and clearly signposted.

For safety reasons, some rights of way may need to be closed for around 48 hours when the company is trenching and laying the pipe into the ground, the company added.

Ian Sarson, senior project manager, said: “Protection and enhancement of the environment are very important to National Grid and we have consulted widely with statutory bodies such as the Environment Agency, English Nature, stakeholders, including the Cotswolds Conservation Board (CCB), and other local farming, conservation and community groups.”

National Grid has appointed PPS Pipeline Services to build the pipeline.
