The Chalk streams crisis in greater Cambridge

Is the Cambridge growth phenomenon about to be derailed by a shortage of water?

For 250 years a chalk stream, diverted into the town centre, provided Cambridge with drinking water. It was a hugely successful public health initiative, supported by both town and university.

Now, pumping from underground chalk aquifers brings potable water at great convenience. But in the process springs are drying up and precious chalk streams are disappearing.

Water companies, regulators, businesses, land owners, consumers and government have overseen a developing groundwater emergency. Can these groups come together to ensure that Cambridge has a reliable water supply without further damaging the environment?


A superb documentary which every developer, politician and consumer should watch. Unmissable!
