STEN Sewer Thermal Energy Network

10/15/2025

STEN positions sewer thermal energy as a form of energy recycling, tapping into waste streams to supply heating or cooling. This is a sustainable activity, reducing the amount of primary energy expenditure and therefore reduces greenhouse gas emissions while achieving the heating and cooling needed within the built environment. The convergence of high heat output from server racks and consistent flow in sewers offers a unique synergy.

By pairing energy-hungry data centers with the untapped thermal potential of sewer systems, we can reimagine urban heat systems, reduce emissions, and turn waste into utility.
