- Description
- With river pollution more in the news than ever before, and sewage now a hot topic, Helen Czerski and Tom Heap investigate how we can restore the health of our rivers. They talk to the Rivers Trust, which this week released its latest ‘State of our Rivers’ report, and ask whether water quality has got better or worse since the last survey three years ago. They delve into the history of our water system - from the creation of the Victorian sewer network after the "Great Stink" of 1858, to the 21st century Thames Tideway Tunnel, London’s super-sewer currently under construction. But have we got our whole water system wrong? Tom and Helen ask whether regarding water as a one-way disposal system has partly created the mess our rivers are in today. They also hear about some waterfleas with remarkable powers to suck pollutants out of water.
