An award-winning, environment-friendly solution to provide heating and cooling for buildings through a heat pump-based technological innovation that uses sewage heat as its renewable energy source. The patented technology generates heating or cooling 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 via heat pumps. The used wastewater is directed back to the sewer lines in a closed system that prevents the leakage of any hazardous material.

A heating and cooling solution for large buildings in 3 stages:
