In the fourth episode of Thames Unfiltered, host Lucy Tobin investigates the Tideway Tunnel — the vast engineering project built beneath the River Thames to tackle London's sewage pollution problem.
Following decades of sewage spills into the river, the £4.6 billion \"super sewer\" was designed to capture millions of tonnes of wastewater that would otherwise overflow into the Thames during heavy rainfall.
But while the tunnel is reducing pollution, can it protect London from the increasing threat of flash flooding?
This episode features interviews with Thames Water's Head of Waste Operations Tim Davies, catchment management expert Alex Nickson, seventh-generation waterman Chris Livett, and Sir Peter Bazalgette.
