Two storm water storage tanks

C2V continue work across the Windermere catchment for United Utilities

We’re continuing to support United Utilities on its £200 million investment programme across the Windermere catchment, with major construction milestones helping to reduce spills and improve water quality.

The programme includes 15 projects, upgrading nine wastewater treatment works and increasing storm water storage capacity at six overflows across the catchment.

C2V are undertaking works at Ambleside storm overflow where construction is progressing on two above-ground storm water storage tanks in Miller Field. Together, they will provide 4,500m³ of storage to hold back storm water during heavy rainfall and help reduce spills. The first tank has now reached its finished height, and the project remains on track for completion by December 2027.

We have also carried out improvement work at Langdale Wastewater Treatment Works, helping to reduce spills at the Elterwater storm overflow. New treatment technology allows the site to process more wastewater to a higher standard and relieve pressure on the sewer network. Additional improvements are planned at the site over the coming years to further improve treatment standards. 

Work is also underway at Troutbeck Wastewater Treatment Works, where our C2V team will be installing new treatment technology to meet tighter environmental standards for phosphorus, biological oxygen demand (BOD) and ammonia.

Construction starts in November at Near Sawrey, on a project to expand the site and improve phosphorus and ammonia removal.

New treatment infrastructure will be installed at both Far Sawrey and Outgate in the coming months to improve the quality of treated wastewater returned to the environment.

"It's great to see the progress being made across the Windermere catchment, with major construction advancing at Ambleside, projects completed at Langdale and Grasmere, and several more schemes set to begin in the coming month. These projects are already delivering benefits for the communities that enjoy Windermere, helping to reduce storm overflow activity, improve wastewater treatment and enhance water quality across the catchment."
