This is a great site that I’ve come across recently: https://discoverwater.co.uk/
It’s full of statistics and information about the whole lifecycle of your water in the UK. Although some of the things they do from a corporate stand point can be questioned, I think that the water companies sometimes get unfairly knocked regarding the work they do. The water supply / wastewater processing businesses are not simple to undertake and a whole lot of engineering, planning, policy making, science and technology goes on in the background to deliver safe, potable water. Have a look around the site and find out all about your water – and then think about supporting the Refill campaign!
