A 10-mile tunnel is proposed to divert sewage from England's largest lake, Windermere.
A feasibility study projects the investment could generate approximately £7.5 billion in economic, environmental, and social benefits. United Utilities states the scheme could return £1.90 for every £1 invested.
This plan forms part of broader £3.6 billion efforts to restore the lake's ecology. Former environment minister Steve Reed pledged government support in March of the previous year to eliminate sewage discharges into Windermere.
The project seeks to connect thousands of people to a modern sewer network for the first time. It also implements natural drainage and flood reduction measures.
Matt Staniek asserts that eliminating sewage pollution will tackle the most significant controllable cause of the problems facing the lake. He claims it will create conditions for ecological recovery, strengthen resilience to climate change, and boost the local economy.
United Utilities has issued an invitation to tender for detailed design work on the project. This phase is expected to take two years.
The Lake District, a Unesco World Heritage site, attracts close to 18 million visitors annually.
Lake Annecy in France faced similar pollution problems in the 1950s. It underwent infrastructural improvements to eliminate sewage discharges.
Proponents of the Windermere proposal claim this alternative scheme provides a 'one and done' approach. They state it will make the lake resilient for the next 100 years, causing less disruption compared to incremental interventions.

One payment option involves passing costs to United Utilities' customers, potentially adding up to £3.17 to monthly bills. The team behind the proposal claims the scheme could add around £3 a month to United Utilities customers' bills, or approximately 33p on bills for customers nationwide if Windermere is recognized as a national asset.
Local residents have expressed opposition to the project. A Department for Environment, Food and Rural Affairs spokesperson stated that further work is needed to test alternative options.
