By Angela R. Ruberto, Juneseok Lee, and Adam Bayer ABSTRACT In this study, water and energy use data (2006–2011) from water wells are analyzed for San Jose State University (SJSU). SJSU is a four-year public university with an enrollment of 30,000 and located in San Jose, CA. It is found out that water and energy use correlate each other, and their use decreased since 2008, due to SJSU sustainability movement. Water savings have significant impacts on associated energy savings, and they double the benef...... continue reading

By David Engle It’s interesting,” observes Ian MacLeod of Master Meter Inc. (Mansfield, TX), “to look at how AMI [Advanced Metering Infrastructure] and the sharing of utility information with users can affect a behavioral change.” To back this up, he cites a three-year study on the psychology of ratepayer conservation, conducted at the Coachella Valley Water District (CVWD) in California and completed in 2011. “Results were almost shocking, in terms of how dramatically people’s water usage was altered w...... continue reading

By Ed Ritchie Welcome to the new era of SCADA, and goodbye to the days of basic supervisory control and data acquisition. Today’s SCADA systems are reaching into most every aspect of a utility’s water distribution and treatment operations, for a true enterprise-wide methodology. And most every stakeholder in the enterprise can benefit if the utility is ready to harness his or her SCADA system’s power. All it takes is the time to investigate, and we’ve looked into some systems that demonstrate the many p...... continue reading

By Dan Rafter The project was a daunting one. The Greater Cincinnati Water Works, a utility that serves 241,000 metered accounts and 1.1 million residents in the city of Cincinnati and surrounding Hamilton County, was upgrading to an automated meter reading (AMR) service. The benefits of upgrading to an AMR system were many: The utility would no longer have to worry about gaining access to the 60% of water meters that were inside commercial and residential buildings. They’d be able to shift worke...... continue reading

By Carol Brzozowski Jeffrey Mosher, the executive director of the National Water Research Institute, says there is a significant role for consulting firms to play in water resource management that transcend engineering consulting firms to include such specialties as groundwater modeling. “We have found it very important to deal with folks like hydrogeologists when dealing with groundwater as a resource,” says Mosher. “The reason I think you see the importance of these consulting firms is because of...... continue reading

By Ed Ritchie When backup power fails at water and wastewater treatment plants, the results can be catastrophic. But the good news is that such events are often avoidable by a proper assessment of backup equipment and disaster planning strategy. For example, a thorough assessment of equipment could have avoided a disaster in Connecticut in late 2011, when tropical storm Irene and October snow resulted in 47 spills with severity ranging from 42.7 million gallons of partially treated sewage dumped ...... continue reading

By David Engle It wouldn’t be exaggerating to say that installing an automated meter-reading infrastructure (AMI) could transform water delivery businesses from top to bottom, particularly ones seeking conservation and efficiency. So far, though, few of the hundreds of AMIs now up-and-running are realizing their potential. (Though some are getting terrific results; see examples below.) What’s the reason? Where are the remedies? The following candid discussion among vendors and adopters explores s...... continue reading

By Dan Rafter When officials with Houweling’s Tomatoes installed two 4.36-MW Jenbacher J624 natural-gas engines in their Camarillo, CA-based greenhouse, they made history. By installing the engines, Houweling’s Tomatoes became the first greenhouse grower in the United States to unveil a combined heat and power (CHP) greenhouse that captures carbon dioxide (CO 2 ) and uses it to fertilize plants.

By Stu Hamilton Introduction Water is the natural capital of the growing world population. Services built on our natural capital are the currency of the 21st century. The timing and spatial distribution of surface water quantity—and the variability in quality of that water—define how we design and build the infrastructure necessary for our energy, agriculture, mining, transportation, and industrial sectors. While water supports our infrastructure, it can also take lives. Droughts and floods are t...... continue reading

By Dan Rafter The city of Enid, OK, used to rely on three meter readers who traveled 5 or 6 miles every day to read between 300 and 350 water meters. This meant that the city utility would get just one reading a month for each of the water meters in this community of more than 50,000 residents. That has now changed. Today, Enid’s water distribution department relies on Neptune Technology Group’s R450 fixed-network Advanced Metering Infrastructure (AMI) system to automatically read its meters remo...... continue reading
