Cranfield University conducts internationally recognized research on water science, engineering and management. The university's Centre for Water Science has expertise in areas like biochemistry, risk assessment, water resources, sanitation, and more. Major challenges addressed by the research include billions lacking access to clean water and sanitation, agriculture's large water usage, and making production more sustainable while using less water. The research develops solutions for industries and aims to make water treatment more energy efficient and close material loops to recover resources like nutrients and energy from wastewater.
2. Internationally-recognized centre of excellence undertaking consultancy, research and training in science, engineering and management of water in the municipal, industrial and natural environments.

13. So what are the major challenges facing the water industry?
14. 2004-06 drought was one of the worst in the last 100 years, hosepipe bans effected 16 million people
15. 30 - 40% of all tap water goes down the toilet
16. UK uses 750,000 tonnes of chemicals to treat drinking water and sewage each year 0.1% of the chemical recycled
17. Energy used to: Supply 1 million litres of water 586 kWh Treat 1 million litres of sewage 634 kWh 2-3% of UK total consumption Emission of greenhouse gas: Supply 1 Ml of water 0.289 tonnes Treat 1 Ml of sewage 0.406 tonnes 0.5% of individuals annual footprint
18. GHG out Treated Water Out Wastewater IN Energy IN Sludge out Traditional sewage treatment produces waste materials and use energy: Sewage works
36. Time for a rethink?Move to: A production facility:
37. What would we like to get to? Reuse water Wastewater IN Energy out Nutrients out Sewage works
38. Fortified anaerobic wastewater treatment could save energy wastewater polishing Primary sed. Second. sed. Effluent disposal Biogas Dewatering and re-use Influent split 25-65% into the anaerobic reactor Anaerobic reactor 44% savings in Energy
49. Recovery and reuse of wastewater – need to be sure you know what's in it!
50. So what's my take home message about water at Cranfield? International leading research on sustainability is in water resources, energy and chemicals. Research is focussed on short and long terms solutions to municipal, industrial and agricultural needs. Run UK’s largest Water MSc programme producing 120 new graduates per year.
