Feasibility study of Using GVRD sewers as heat sources and sinks
Executive Summary As pari of the Sustainable Region Initiative (SRI) the Greater Vancouver Regional District (GRVD) Policy and Planning Department has commissioned this study to investigate the use of district sewers as heat sources or heat sinks. This conceptual study examines the technology available for sewer heat transfer, and provides a mathematical and physical model of a heat transfer ...

Modelling the viability of heat recovery from combined sewers
Modelling of wastewater temperatures along a sewer pipe using energy balance equations and assuming steady-state conditions was achieved. Modelling error was calculated, by comparing the predicted temperature drop to measured ones in three combined sewers, and was found to have an overall root mean squared error of 0.37 K. Downstream measured wastewater temperature was plotted against modelled ...

Investigating the interactions of decentralized and centralized wastewater heat recovery systems
In the urban water cycle there are different sources for extracting energy. In addition to potential and chemical energy in the wastewater, thermal energy can also be recovered. Heat can be recovered from the wastewater with heat exchangers that are located decentralized and/or centralized at several locations throughout the system. It can be recovered directly at the source (e.g. in the ...

Indoor Air Quality in the Mid-Atlantic States
Indoor air quality is an issue in the Middle Atlantic States (VA, MD, DE, NJ, NY, PA, and CT) simply because 25% of the U.S. population lives and works there! Further, it truly has four (4) seasons. Floods and mold in the spring, heat and humidity in the summer, pollen, ozone, hurricanes in the fall, snow, sleet, and ice in the winter. Indoor air quality in our homes, transportation, offices, and ...

How to tap the energy savings in greywater
Many operators of offices, hospitals, hotels, large condos, and other buildings are aware of the need to save money and reduce their environmental impact, through better water management. The result has been the growth of ways to reduce water consumption, ranging from low-flow show-crheads to landscaping that requires minimal watering. Building operators are also aware of a similar need to ...
