energy supply and management strategy.

FOR A DEEP DIVE INTO ENERGY FROM
WASTEWATER, PLEASE SEE UHRIG’S WHITE
PAPER, ENERGY FROM WASTEWATER:
UNDISCOVERED POTENTIAL FOR THE HEAT
TURNAROUND. KEY TAKEAWAYS:
▶ Energy from wastewater has the potential to cover
about 15% of all heating and cooling needs.
▶ The potential of wastewater lies at 101.4 TWh/a.
Valued conservatively, this potential will increase ABOUT UHRIG
by about 35 TWh by 2030.
▶ In urban areas, the relationship between German technology leader UHRIG has specialized in
wastewater supply and the demand for energy wastewater and rainwater systems for more than
generation is particularly favorable. 50 years, and completed almost 100 Energy from
Wastewater Projects throughout Europe. Wherever
you are in the world, UHRIG is ready to reduce your
energy costs and achieve your sustainability goals.
