Introduction

Are we running out of water? Britain may be known for its rain but, as our climate changes, there are warnings we could be closer than we think to our taps running dry.

In this episode of Troubled Water, James Gallagher asks why our pipes are being pushed to the brink and what can be done about it, all from the comfort of his bathroom. Huddled in the loo, he talks to Professor Hannah Cloke, OBE, who predicts rainfall events through her work at the University of Reading, Dr Francis Hassard, from the Water Science Institute at Cranfield University, Andrew Tucker who manages water demand at Thames Water and inventor Garry Moore who shows how he's hoping to revolutionise our loos with his air-pressurised Velocity toilet.
