What is the most important building in London's history？St Paul's Cathedral？Westminster Abbey？The Tower of London？My vote goes to a grand 19th century building-the Crossness Pumping Station．
While Crossness Pumping Station may not feature on a postcard，it has perhaps played a bigger part in changing the lives of ordinary Londoners than any other building，saving thousands from death and diseases．
I have to admit Tm not fair．My great-great-great grandfather Sir Joseph Bazalgette designed and built Crossness，which celebrated its 150th anniversary on 3rd April．When we step inside，it looks more like a palace than a sewage treatment （污水治理） works，with red pillars （柱子） and elegant iron lattice （格子） in green and gold．But this was a building with a purpose：setting out to save a city drowning in its own waste，at a time when Londoners were quite literally seeing sewage coming up through their floorboards．
Let me take you back to London before 1865．The industrial revolution had swept through Britain；the urban population had swollen；people were living in overcrowded，unhealthy places．Some infectious diseases were filled with the place．Life expectancy was less than 20 years for people in some towns and cities and many people had no access to clean water．
Soon after the Crossness opened，London was as far apart as heaven and earth：an advanced system of 1100 miles of flowing water in underground tunnels，taking away 31 billion gallons of sewage per year and washing diseases off the streets of London town．This may seem common sense now，but at that time it was revolutionary thinking．
But it was not just a brave old fashioned Victorian engineering that changed the life of people in London；it is also a clever design that may bring the problem in other places under control now．It means there can be hope in a place like London that used to be years ago．We can change the life of people who live in dangerously unhealthy conditions．Over 748 million people around the world still don't have access to clean water，while about 2.5 billion people do not have access to a toilet．We may learn from the Crossness Pumping Station and make them live better．
