Sewage spill monitors extend reach to cover all England

After the BBC queried how it had managed to reach 100% this year, Thames Water said that as well as adding monitors it had found after closer examination that 158 of the overflows it reported in 2022 did not in fact need to have a monitor installed. In these cases, a Thames spokesman explained, outfalls were discovered to no longer be connected to the sewage network or to be duplicates of other outfall permits.
