An update on our work around Windermere

Drop-in at Ambleside

Going further to take treatment around Windermere to the next level 

More than £75 million has already been spent upgrading the wastewater treatment and network around Windermere. 

Going further we’re now investing up to £200 million which will reduce spills from the six overflows, which can discharge into the lake, to an average of less than ten per year. While also taking standards at the treatment works to a higher level or the highest achievable standard using the best available technology. 

This investment would see improvements to wastewater treatment sites at: Ambleside, Far Sawrey, Ferry House, Grasmere, Hawkshead, Langdale, Near Sawrey, Outgate and Troutbeck, helping improve treatment for phosphorus and creating extra storage capacity to store stormwater. 

Large schemes gated process

12 of our projects at Windermere are going through Ofwat's large schemes gated process. This process requires us to provide Ofwat with two submissions on scope, cost and programme to allow Ofwat to approve funding for delivery of the schemes.

The first of these submissions sets out progress of scheme design and feasibility assessments and is an update to Ofwat rather than a decision-making point. We made this first submission on 1 October for the following groups of schemes:

What you can expect to see 

To help our engineers develop our plans for all of these sites, you may see some activity taking place around the area. Our work will include ground investigation surveys. These help us understand the local geology and rock formation. We carry out various surveys to confirm ground conditions or the location of other utility pipes and cables. 

The surveys and investigations may involve digging or drilling small holes into the ground using specialist equipment or clearing shrubs and vegetation before the main work is due to begin. 

We’ll also be carrying out ecological and wildlife surveys. These help us understand and identify areas where we need to keep construction to a minimum, protecting the environment and habitats around us. 

This work will not impact your existing water and wastewater services and we’ll endeavour to keep any disruption to a minimum.
