The sewage plant of Mainburg was generally overhauled between the 2000 and 2002. As part of this modernisation, the boiler dating from 1967 used to heat the digester and the service building was replaced by a modern WOLF CHP unit. No longer was it necessary to burn the sewage gas in a boiler, instead it was used to drive the CHP unit. The CHP unit is driven by an MAN engine and comes fully wired in a container. It generates 52 kW electrical and 80 kW thermal output.
