A visitor to the Western Treatment Plant coined the term ‘Pootricity’ and we like it. What is ‘Pootricity’? It is electricity generated from gases captured in the sewage process (biogases). Pond 1 of the sewage lagoon process at the Western Treatment Plant is partially covered to capture gases such as methane and this is then used to generate electricity to run the plant. Already the Western Treatment Plant provides enough electricity for 95% of its annual electricity requirements. This figure will soon be 100% as the covers are increasing in 2012 to double the size.
