168. Water under pressure Greenbank Institution of Engineering and Technology, 2 Savoy Place 24 April 2024

I attended this Investor day as a Trustee of the Water Conservation Trust and interested in the headline subject.  It turned out to be far more fascinating than I had expected.  The speakers :

·         Kate Elliot, Head of Ethical, Sustainable and Impact Research, Greenbank

·         Kai Johns, Senior Ethical, Sustainable and Impact Researcher, Greenbank

·         Claire Elsdon, Director of Capital Markets, CDP

·         Jason Shingleton, Group Material Science Director

·         Martin Gisbourne, Chief Strategy and Sustainability Officer, Genuit

They were all very interesting, identifying issues globally across water and the need for action as well as where they were specifically involved and supporting local initiatives.

I have reproduced some of their slides, which reflected their messages for me.




We then heard from Professor Wouter Buytaert from Imperial College who gave a great presentation.  He explained that the “Water Crisis” is two crises - the physical scarcity of water and the shortage of safe drinking water.  Household water requirements represent a tiny fraction of global water use, usually less than 10% of the total, but there is a tremendous inequality in access to clean water and sanitation at a household level.  In England we abstract 9,500 billion litres per year and consume 140 litres on average per person per day.  We consume about 30 times as much indirectly, through the production of energy and imported food and textiles.  This is equivalent to 4745 litres per day.

The water industry needs to resist the urge simply to do the minimum required to meet regulations.  This does not mean simply more policing/enforcement but also systems that facilitate policy makers, water managers, and other stakeholders better to understand water systems and what they should deliver.

He said we need to take a leading role in delivering sustainable water and wastewater infrastructure, ensuring a provision that is resilient both to the conditions we face today and to the changes in population and weather patterns we can expect in the future.

It was a stimulating, thought provoking day.
