Environmental campaigners and the local water company United Utilities have come up with a plan to build a huge sewage tunnel at Lake Windermere coming at a cost of more than £3.6 billion. The plan is not yet approved but there are two proposals to fund the project: either taxpayers or United Utilities customers in the north west pay. Lake Windermere is England’s largest natural lake and a UNESCO World Heritage site but has also been at the epicentre of the arguments over sewage. We spoke with the CEO of United Utilities Louise Beardmore. #News #Channel4News #LakeWindermere #Sewage #UK
