Energy utilization in the sewer:
communal sewage, industrial waste water

The sewage in sewers is an ideal energy source for the heating and cooling of buildings. Based on long experience, sewage quantities of more than 10 l/s and a temperature level above 10°C are the minimum requirements for this form of energy recovery. In the implementation, heat exchangers are fitted in sewers of the most varied cross-section geometries or the waste water passes through an external heat exchanger.
