The international news resource for industrial & municipal water professionals
Tucson Water learned critical lessons about water treatment decision-making, customer communication, and public involvement in its first attempt to take its then-500,000 customers from groundwater dependence to surface water supply. The water department is the largest municipal provider in southern Arizona. It applied those lessons in a second attempt that succeeded and soon will be expanded.
In the last 20 years, water quality managers have come to more fully appreciate that the old categories of both management and regulation are breaking down and collapsing in upon themselves. Quantity versus quality, surface versus groundwater, point versus nonpoint sources, chemical versus physical and biological integrity—these are the traditional cookie jars in which we separated management of what is really an integrated resource characterized by the connectivity of all its component parts.
Major judicial decisions continue to shape water law in significant ways even though the Clean Water Act is 35 years old. Recent court decisions have shown a willingness of parties to attack the policies and programs of the U.S. Environmental Protection Agency and U.S. Army Corps of Engineers, and some courts have disregarded "judicial deference" to EPA.
2007 was another typical year for the water industry – full of challenges, surprises, frustrations and complexities, but also offering new opportunities. The job of the water utility – to provide safe and affordable water – may sound easy, but in many ways the job continues to get tougher and tougher.
Are you keeping up with the Joneses? The plant down the street replaced its sequencing batch reactor with a membrane bioreactor. And the cross-town facility opted for ultraviolet over its chlorine disinfection program. What's the water industry coming to?
Why is operator math necessary? It is needed to evaluate how well a plant is performing, or what the plant is capable of treating adequately. State authorities consider the topic important enough to include at least a little math on even the lowest level certification exams.
Reliability is paramount to the monitoring and control of water/wastewater facilities. With facilities relying on real-time data transfer between remote systems and plant control areas, managers and operators cannot afford downtime or errors in information transfer.
The view of our planet from space masks a perplexing irony. With water covering 71 percent of the Earth’s surface, we would expect plenty of this life-sustaining resource to go around. American Rivers, a river conservation organization, recently commended the Georgia Environmental Facilities Authority for promoting water efficiency as the first source of supply in its recently released study,
