Over 10 billion litres of sewage are produced each day in the UK. Treating this volume of sewage uses over 2,000 gigawatt hours of electricity a year - almost 1% of total UK electricity consumption, and the equivalent of 5 million tones of CO2 emissions. http://www.wskep.net/index.php/waterr2b/sectors/water-utilities/micro-bubbles/
