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 is roughly 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 of consumables 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 EU-funded project POWERSTEP, new technologies and concepts for energy positive wastewater treatment are being tested in close cooperation between research and industry in existing sewage treatment plants.

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


Our first regional workshop took place in Döbeln, Germany in October 2017. Read about the workshop and its outcomes here.
