Outrage as ‘tidal wave’ of sewage floods historic market town’s unique chalk river continuously for months

Sewage has been pumped into one of the country’s most unique rivers for nearly five months, including 21 days when it was not raining, The Independent can reveal.

Thames Water, which serves Greater London and the Thames Valley, has discharged waste from its site in Amersham into the Misbourne river continuously between 25 January and 5 June.

Water companies say they only activate ‘storm overflows’ during extreme weather and heavy rain.

But human waste was also.
