Abstract

Energy is the second largest cost to a water utility, behind manpower, and it is forecast to significantly increase. Not only does the urban water cycle need energy to operate, it also contains both thermal and chemical energy. Researchers have identified that the urban water cycle in Amsterdam has enough potential energy to offset all of the greenhouse gas emissions presently emitted to operate it. One method used to recover this potential available energy is to extract heat from sewers. The first examples appeared in Europe over 30 years ago, and there are now over 500 wastewater heat pumps in use worldwide. Our challenge was to determine if heat extraction from sewers was both technically..
