By Joe Guagno, Chris Lawrence, Martha Senf, Thomas Devine, Lenny Gold Energy accounts for about one third of the operating budget for drinking water and wastewater systems. It’s a facility’s largest controllable budget item, so it’s a logical place to look for savings. The most important step in reducing energy costs is to have a good understanding of where the energy is being used in the facility. The first step is to conduct an energy audit to evaluate possible operational adjustments and concepts, co...... continue reading

By David Engle Despite some setbacks and challenges, every year hundreds of Advanced Metering Infrastructure (AMI) networks are smoothly and efficiently deployed. Better still, they’re now delivering exceptional benefits for water services and ratepayers alike. When a utility makes the choice to move forward with a large-scale AMI or automated meter reading (AMR) installation, there are two primary challenges that utility can expect to face: installation and data handling. Installation is often subcontr...... continue reading

By John E. Regnier Introduction Electrical bills are not ordinarily thought of as anything other than a necessary aggravation in the complicated process of producing and delivering drinking water to a customer or collecting and treating the wastewater from that customer. Surprisingly however, these bills, with a little effort, can become one of the best tools the water manager has in his toolkit. They can be useful both as an operational aid and especially as a guide to saving money and the energy it re...... continue reading

By Ed Ritchie “We need to address the medium-sized utilities that don’t know that consultancies can provide them with these simulations and models that can help them understand the cost over 10, 15, and 20 years,” says Terry D. Bennett, LS LPF MRICS LEED AP, senior industry program manager and strategist for civil engineering and planning at Autodesk. “If you look at the average age of operators at a water utility, it’s clear that in the next 10 years, there’s going to be a massive brain drain and a lot...... continue reading

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
