Super sewage treatment A regular sewage plant for  28,000 people costs about €225,000 a year to run according to figures from Germany. Installing a new form of digester unit (many sewage plants don’t have them) made by IGB, shortened the digestion process from 30-50 days down to 5-7 days. In addition there is reduction in the residue by about 1/3 which reduces disposal cost by €70,000 a year. In addition, sewage plants us a lot of electricity in the process. The biogas produced by the digester can provide enough electricity to reduce costs by a further €100,000 a year. A bit of a no-brainer?
