By Steve Goldberg Although various forms of rainwater harvesting have been used for thousands of years, as an organized industry, it is still in its infancy. At present, no national standards are in place regulating its use, although various states and municipalities have begun promulgating laws concerning how rainwater may (or may not) be used. The rainwater harvesting industry has a national organization, the American Rainwater Catchment Systems Association. It is presently headed by David Crawford, p...... 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 Lori Lovely Most people turn on the tap at home, expecting an endless supply of clean water. They also expect the bill for that water to be minimal. After all, water falls free from the sky—shouldn’t it be cheap and abundant? As a familiar adage rationalizes, the water is free; you just have to pay for treatment and delivery. Not surprisingly, those costs are going up. What’s perhaps a little more astonishing is the shortage of water in many areas. Water resources everywhere have been stressed by agi...... 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 Spencer Miller, USDA Natural Resources Conservation Service The water cycle is usually illustrated as a circular flow chart depicting water’s endless journey between ground and sky, rain and vapor. In Western states, where the majority of water falls as snow, the process works a bit differently. Western mountains have snowpack, a reservoir of frozen water that melts and fills streams during dry spring and summer months. Too much snow or quickly-melting snow might mean flooding. A deficit could cause w...... continue reading

BOULDER, Colo. (April 17, 2013) — The Colorado River is the most endangered river in the United States, according to the 2013 list of America’s Most Endangered Rivers® released today by the nonprofit group American Rivers. Western Resource Advocates, a conservation organization that works throughout the entire Colorado River Basin, issued the following comments in response to the new listing: “We all have our own dreams and visions for the future of the West,” said Bart Miller, Water Program Director at ...... 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 Elizabeth Cutright In a recent blog post (“ Water . . . Right Here All Along ”), I asked, “what if we already had enough water to meet our needs?” The answer to that question, according to panelists who participated in a discussion hosted by New York Academy of Sciences in February , is that we do have enough water—we just don’t have enough conservation. The panelists, including Brian Richter (director of global freshwater strategies for The Nature Conservancy), Peter Gleick (co-founder of the nonpro...... continue reading
