From Thirlmere to West Cumbria
We'll be using Thirlmere as the new source to supply drinking water for homes and businesses in West Cumbria.
The water will then be transferred along twin 30km new pipelines to a new water treatment works just off the A595 near Redmain. The overview map (PDF 90KB opens in new window) illustrates all elements of the West Cumbria Water Supplies project.
We've taken great care during our planning and design of the pipeline to avoid the hilly terrain, environmentally designated sites, archaeological sites and urban areas.
The pipelines have been constructed to make the most of gravity and utilise the natural contours of the land, allowing the water to travel easily along the pipes without the need for pumps.
The majority of the pipeline has been constructed across agricultural land. Carrying out a large proportion of our work in the fields during the spring and summer period helped to reduce the impact on the grassland.
There are several points on the pipeline route where we've tunnelled under rivers or key road crossings. We've now completed all five tunnel sections; crossing under the River Greta, our longest tunnel section in the Castlerigg area, two tunnels in Keswick and another in the Cockermouth area which accommodates the pipe as it runs under the River Derwent and A66.
You can see the latest progress on our West Cumbria update page.
We're on schedule to have the project completed and the pipeline in use in spring 2022.
