West CumbriaWest Cumbria update

Since starting construction in 2017, our teams have been working hard to install the new pipelines, refurbish old pipes, build new pumping stations, a new state-of-the-art treatment works and two new underground storage reservoirs. 

Despite many challenges including dry weather, extreme wet weather and flooding...even the impact of Covid-19, we're now in the final stages of this unique project which will supply over 80,000 homes and businesses with water from Thirlmere. We've created a more resilient and sustainable water network. 

We're almost ready to bring a new source of Lakeland water to homes and businesses in West Cumbria and start to supply customers with Thirlmere water from July 2022 onwards.  We'll be providing regular updates. You can find further information on our dedicated hub.

    Land reinstatement is continuing across the project which involves removal of stones, preparing the land to replace the top soil and eventually re-seeding.  We have a number of teams who are progressing in stages along the route. The images below demonstrate just how well the land recovers in a short space of time.

    Weather conditions have a major influence on the reinstatement activity, and at the moment the weather appears to be quite unpredictable which may impact on our progress across the working areas.

    The images below show the recovery around our working areas before and after land reinstatement.

  • The new state-of-the-art site incorporates a living green roof and complements the natural contours of the surrounding environment. When it's brought into operation it will be treating up to 80 million litres of quality Lakeland water every day.

  • The two new sites will be storing the treated water arriving from Williamsgate in huge underground tanks, ready to distribute along pipes to homes and businesses. 

    High Leys is the largest of the two service reservoirs - storing 50 million litres of treated water.  The image shows how the new service reservoir has been designed to integrate into the surrounding landscape.

    Moota Hill is the smaller capacity service reservoir, but it will still be capable of holding an impressive 21 million litres of water!

  • We've refurbished the existing water pipe network from Cornhow in the Lorton Valley, through to Stainburn Service Reservoir near Workington.

    Unlike the water transferring from Thirlmere to the new treatment works which travels by gravity, the treated water needs some help to travel along the pipe network to your home. In the Cockermouth area we've built a new pumping station and installed new connections to help the water continue it's journey.

    Thank you for your ongoing patience while we've been working.  We do understand that the scale of this project has involved a lot more construction traffic, noise and disruption for the community.  If you have any queries you can always call us on 0345 672 3723.
