Lake District

BBC NEWS and BBC ONE West reported that Windermere, England's largest lake, has experienced algal blooms that turn the water green, caused by warming temperatures and nutrients entering the lake, mainly from sewage and partly from agriculture. They said a report has been published on the feasibility of stopping all sewage discharges into the lake. The plan, developed by Stantec with the local water company, regulators and local authorities, would connect homes near the lake to the sewage network and use a tunnel about four metres wide and up to 19 kilometres long to take sewage for treatment and discharge in or near the Irish Sea. The channels said the project would cost £3.6bn and, if approved, take seven years to build. Funding could come from a £3 a month increase on local bills or a rise of about 35p a month levied on everyone across England. They reported that the government will decide whether it wants more research done on the plan, and that United Utilities would likely be responsible for building the tunnel. The BBC said it had documented the company spilling raw sewage into the lake and questioned its past investment; the company said it had invested hundreds of millions of pounds but not enough and described the tunnel as a 100-year solution. ITV1 reported that United Utilities is backing the £3.6bn plan, which would connect 12,800 homes, and that the company plans £200m of investment over five years to reduce combined sewer overflows. ITV1 also reported that an algal bloom in 2022 turned the whole lake green and that campaigners say the cost of keeping the lake clean is worth paying.
