It may seem incredible that an entire hospital can be powered by energy captured from city sewers. But it is happening in Toronto, Ontario, where the world’s largest wastewater energy-transfer project is almost complete and the city is on the path to becoming one of the world’s leaders in water/wastewater energy projects.
