This paper summarizes the outcomes of the international sustainable energy management workshop as part of the Water Research Foundation project "Decision Support System for Sustainable Energy Management." This paper provides a review of key decisions and barriers to water utility energy management. This paper also provides a discussion of a decision framework to address sustainable energy management in the water/wastewater industry. This work represents a 17 utility, international cooperative project, aimed at creating a Decision Support System (DSS). When concluded, the assembled tool is expected to help identify energy, greenhouse, and cost-saving approaches that will be of wide practical benefit to water utilities. © IWA Publishing 2010.

Why electrified transportation? Why now? For decades, inventors, manufacturers, and consumers have tinkered with the idea of electrifying transportation. To date, however, the global transportation fleet remains fossil fuel based. Other technologies such as hydrogen fuel cells and biofuels have also been "on the near horizon" for years. So what makes electrifi ed transportation feasible now, and how likely is it that it will transform the transportation sector? Let's look at the facts. © 2010 IEEE.

Saint Paul Regional Water Services (SPRWS) from Minnesota, US, implemented two customer information system (CIS) to save time and money, while providing more efficient service to the utility's customers. The benefits from these systems included greater access to valuable customer, work, and asset data for more staff, improved customer service, expanded capability, improved efficiency, streamlined work processes, and cost savings. Detailed planning, careful thought about functional requirements, and staff involvement from all areas of the utility at all points of the process supported the project's success. SPRWS began the process to replace its existing billing system following its five-year information technology (IT) roadmap. SPRWS took the requisite preparatory steps to become informed before undertaking the project.

The American Society of Civil Engineers' annual report card shows a decreasing trend in the condition of drinking water infrastructure in the United States during the past 20 years. Maintenance and improvement of the nation's drinking water infrastructure and utilities are required. This can only be done after utilities' current performance is evaluated and may only be possible after the performance metrics have been evaluated and benchmarked against other utilities. A few initiatives exist in this area, but they are hindered by subjectivity, limited scope, the ability to gather utility personnel at one place, and the fact that they've been completed only once. This article documents the results of quantitative, comprehensive, and web-based performance benchmarking of 10 utilities in seven key areas. This research yielded the creation of a database and a web-based data collection and result display platform that is a part of the Water Infrastructure Database (WATER/D) project.
