State-of-the-art innovation

THERMOWATT Technology

Our state-of-the-art heat pump-based technological innovation generates green energy from communal wastewater by directing it from the sewer lines to heat exchangers. The energy recovered by the exchangers is used for the heating and cooling of buildings with the use of heat pumps. The used wastewater is directed back to the sewer lines in a closed system that prevents the leakage of any hazardous material.

After the implementation of our proprietary and cost-effective heat utilization technology, we also undertake the operation and management of the system.
