An evening with Nick Higham

PRIVATE GREED, PUBLIC GOOD: A History of London’s Water

No city can survive without water, and lots of it. Today we take the stuff for granted: turn a tap and it gushes out. But it wasn't always so. For centuries London, one of the largest and richest cities in the world, struggled to supply its citizens with reliable, clean water.

The Mercenary River tells the story of that struggle from the middle ages to the present day. Based on new research, it tells a tale of remarkable technological, scientific and organisational breakthroughs; but also a story of greed and complacency, high finance and low politics.

Amongst many stories, Nick Higham's page-turning narrative uncovers the murky tale of how the most powerful steam engine in the world was first brought to London; the extraordinary story of how one Victorian London water company deliberately cut off 2,000 households, even though it knew they had no alternative source of supply; the details of a financial scandal which brought two of the water companies close to collapse in the 1870s; and finally asks whether today's 21st century water companies are an improvement on their Victorian predecessors.
