This document discusses how smart water meters can help consumers save energy and water. It outlines how water heating accounts for a large portion of energy costs, and that providing consumers with near real-time usage data through smart meters and feedback tools can help them better understand their usage patterns and find ways to reduce consumption. The document then describes a proof of concept by a Dutch utility that combined smart gas, electricity, and water meter data into a single display. Consumer responses found that most felt more aware of their water usage, and many were able to identify major energy uses from the combined data display. The utility concluded consumers want easy access to combined usage data in graphical form to help them save resources.
