3 mentors from Thames Water gave a fascinating insight to 5 mentees from The Leigh UTC.
Long Reach Sewage Treatment Works serves a population of approximately 900,000 people, covering a 200,000 square mile catchment area in Kent.
The main sewage treatment works were constructed between 1921-1926, built on the original works which date back to the late 1800’s. Since then, Long Reach STW has grown to meet the demands of an increasing population and with developments in technology. As well as treating waste water before returning it to the Thames River, the site also produces biogas from sludge which is then used to generate electricity to help power the site -a Thermal Hydrolysis Plant (THP) is used to help optimise energy recovery at this stage. The site also utilises a Fat, Oil and Grease (FOG) processing plant which produces biodiesel from left over cooking oil.
A great day was had by all and we would like to a thank Phil Gilley, Julie Carter and Gregory Baker from Thames Water who gave our students the opportunity to visit the Long Reach Sewage Centre.
