The Envision Sustainable Infrastructure Rating System provides a framework for evaluating and rating the community, environmental and economic benefits of all types of infrastructure projects; and provides a basis for evaluating, grading and recognizing infrastructure projects that use collaborative approaches to assess the sustainability indicators over a project’s lifecycle.
For water utility managers, the recession and years since have been full of trials and tough decisions. In spite of these economic challenges, utilities have fared better than most sectors, managing to post favorable financial and debt profiles given their essential service nature, which have preserved a baseline level of demand.
Because of heavy drought over the last few years, the city of Wichita Falls, Texas, implemented a direct potable water reuse system and turned to the use of high-density polyethylene pipe to better source water in the region.
Elsinore Valley Municipal Water District of California implemented a unified GIS-enabled mobile solution to better process customer service workflows, CMMS work orders and other field workflows, as well as replace its hardcopy facility atlas data with a robust electronic mobile atlas.
An upgraded pump benefits water processors and water consumers alike. Further, upgraded pumps avoid risk areas in the mechanical portion commonly called the drive-end.
Rainwater harvesting is rapidly becoming a standard process for many homeowners, institutions and industrial plants as a way to collect a natural resource and use it to reduce the amount and cost of purchased treated water.
NASA’s newly-developed Global Precipitation Measurement mission comprises a network of nine internationally-coordinated satellites that provide highly-accurate and instantaneous projections of rain and snow every three to four hours over 90 percent of the globe.

Last month, I wrote about the winners of the 2014 U.S. Water Prize, a program that celebrates "one water" champions — be they public, private, industrial, or non-profit. Since then, I've had the opportunity to speak with one of the winning project teams and learn more about their remarkable accomplishments.
Cyber-attacks on water systems and other critical infrastructure are gaining increased attention in Washington. Further, cybersecurity legislation is pending in Congress and could become a reality this session.
Water hammer is a destructive force that can exist in any pumping installation where the rate of flow changes abruptly for various reasons. It is thus essential for an engineer to know when to expect water hammer, how to estimate the possible maximum pressure rise, and how to provide a means for reducing the rise to a safe limit.
Population growth, global trends toward urbanization and the emergence of a growing middle class in the developing world are poised to require freshwater at levels stretching our ability to support them. However, innovations in the industry will solve these issues, and many companies will develop innovative solutions to address these emerging needs.
The Cedar Cove lift station in Fishers, Ind., had two unreliable submersible pumps that were frequently failing due to clogging and seal damage. As such, the town replaced them with two Barnes 4SHV vortex solids handling pumps specifically engineered to prevent against clogging occurrences and increase seal life.
