Yesterday, several AAFAF WET Project members were invited to the Only Rainwater launch. The feasibility study has been completed and the next stage is to put the project out to tender. It was a positive presentation which promises to remove the majority of human pollution from the catchment of Windermere via an ambitious program of connecting current package treatment plants and septic tanks to the mains, separating some of the currently mixed sewer and rainwater drains, adding in SUDS and reedbeds and sending the sewage from all the treatment works around Windermere down a huge pipe to a newly built state of the art treatment works outside of the national park. The new treatment works will be of a far higher spec than currently required by government and has already been trialled in Europe. The timeline is for it to take 7 years from the awarding of the tender. The cost to bill payers will be 35p a month if Government agrees to it being shared across all water companies because of it being a national park, or ÂŁ3.17 a month if only UU customers pay. Cost / benefit analysis to the local businesses is that ÂŁ1.90 of extra money will be spent by visitors to the region for every ÂŁ1 spent on this project to clean up the lake.

Louise Beardmore also thanked the residents of Ambleside for being patient and helpful as UU builds our new holding tanks to prevent spills into the lake. We need those tanks for the next decade until the pipeline is built, and they will also enable the future sewage to be sent down the pipeline without backing up. https://www.unitedutilities.com/corporate/newsroom/latest-news/coalition-publishes-landmark-blueprint-for-only-rainwater-into-windermere/

Don't forget to come and hear what the WET Project found out about the cleanliness of the lake at Waterhead this year through weekly lab testing - Wed 4th Nov 7.30pm Ambleside Parish Centre and we will have some copies of the Only Rainwater feasibility report there. aafaf.uk/wet
