Turn your sewage treatment plant into a power station and actively contribute to climate protection in your municipality!

The municipal wastewater in Europe contains an available chemical energy of about 87,500 GWh per year. This corresponds roughly to the capacity of 12 large power plants. Due to the currently used technologies and the associated energy loss in the individual process steps, sewage treatment in Europe instead consumes primary energy of more than two power plants.

The use of the available chemical energy represents a great opportunity for municipalities, wastewater associations and operators of sewage treatment plants to evolve from an energy user to an energy producer and thus, on the one hand, to reduce costs and, on the other hand, provide an important contribution to climate protection and energy transition.

In the framework of the Horizon 2020 project "POWERSTEP” new technologies and concepts have been tested in close cooperation between research and industry in order to make the energy content of the sewage water available on existing sewage treatment plants without major investments.

To introduce the concept of energy positive wastewater treatment plant to representatives of municipalities, four regional workshops were organised during the POWERSTEP project. These workshops targeted innovative municipalities with ambitious environmental and climate goals.


The workshops took place in Döbeln, Germany in October 2017; in Bottrop, Germany in February 2018; in Timisoara, Romania in April 2018; and most recently in Altenrhein, Switzerland in June 2018.
