The Potential for Energy Savings with Water Conservation Devices

摘要

Through a survey of water-related energy use, a relationship between water usage and energy consumption is developed. Results obtained indicate that energy requirements for water heating far exceed those for water supply and wastewater treatment. Based on estimates of residential water consumption with and without water conserving products, the potential for energy savings is assessed. Reduction in household water heating energy consumption of about 35 percent are predicted with the use of conventional water saving products. Also considered in this study are the energy saving potentials of grey water recycling and grey water heat recovery systems.
