Sewage has become a major battleground in the local elections in so-called “blue wall” seats, where the Liberal Democrats are challenging the Conservatives, from Guildford to Cambridgeshire.
The Lib Dems have put eliminating sewage dumps at the heart of their campaign, with the party leader, Ed Davey, planning to launch their fight at the River Wandle in Wimbledon on Wednesday. He is calling for a tax on sewage companies to fund the clean up of local rivers, which can see waste pumped out into the environment when there is heavy rainfall.
