Untreated effluent was released into waterways for more than three million hours last year. According to the BBC: Sir James Bevan, chief executive of the Environment Agency, said that his organisation was "working actively with the water companies to ensure overflows are properly controlled". He also said that the harm they do to the environment needed to be stopped.
The Rivers Trust, which campaigns to protect river environments in England and Wales, said: "This is a shocking volume of untreated contaminated wastewater reaching our rivers and shows that our current approach and infrastructure, managing storm water in particular, needs a radical overhaul."
