According to figures obtained by the Liberal Democrats, 72 billion litres (29,000 Olympic swimming pools) have been pumped into the river by Thames Water in under three years. Mogden near Twickenham was the worst affected site, where 17.1 billion litres of sewage was discharged into the river, closely followed by Crossness in east London, where 15.8 billion litres of sewage was dumped. Naturally these statistics weren’t divulged by Thames Water as they only havea legal obligation to publish the number of hours it’s pumping sewage into London’s river, not the actual volume of the discharges. If you paid a man to dispose of your rubbish, only to find he’d dumped it, you’d call him a crook, and yet we pay water companies to remove our sewage, only to find it dumped in the nearest river.
