WE&T Magazine

WET_cover1_Aug15-90Water Environment & Technology (WE&T) is the premier magazine for the water quality field. WE&T provides information on what professionals demand: cutting-edge technologies, innovative solutions, operations and maintenance, regulatory and legislative impacts, and professional development.


August 2015, Vol. 27, No.8

When Chicago hosts WEFTEC® 2015 participants will have the opportunity to learn from an extensive technical program, explore a vast exhibition, and network with thousands of water professionals.
See what topics are top of mind this year and discover the best opportunities to meet other water professionals.

Sharing the risk

feature 1 art

The City of Casselberry, Fla., anticipated that the promulgation of the U.S. Environmental Protection Agency (EPA) Stage 2 disinfectant/disinfection byproduct (DBP) rule would lead to compliance difficulties at its South Water Treatment Plant. Even before the rule took effect, the city was working toward a fix. Significant time constraints to perform improvements emerged during negotiations with the Florida Department of Environmental Protection (DEP). 

To address these constraints, Casselberry chose an alternate project delivery method: a method known as construction manager at risk (CMAR). The city recently had success using the CMAR method to remodel its water and wastewater operational facilities.  


Membranes for the masses

feature 3

Treating wastewater for reuse is an increasingly necessary practice. Membrane-based water reuse is an emerging area mainly due to the ability of membranes to remove contaminants of concern. Metro Vancouver in British Columbia, Canada, conducted a study to assess the feasibility of treating trickling filter, solids contact effluent for reuse.   

The study was conducted using three different membrane pilot systems, supplied by leading membrane manufacturers, to assess their effectiveness.

U.S. EPA proposes rule to restrict acceptance of hydraulic fracturing wastewater 

The proper treatment and disposal of wastewater from hydraulic fracturing continues to be a national issue. In response to public concerns about health and the environment, the U.S. Environmental Protection Agency (EPA) released on April 7 a proposed rule regarding technology-based pretreatment standards under the Clean Water Act that would restrict the discharge of this brine to water resource recovery facilities (WRRFs) — referred to as publicly owned treatment works (POTWs) by EPA — from existing and new unconventional oil and natural gas (UOG) extraction facilities.

Full-range of perspectives

It’s fitting that the September issue will be distributed at WEFTEC®, the most comprehensive water show in the U.S. In addition to having more feature articles than almost any other issue of WE&T — eight are planned — this issue, like WEFTEC, will present related topics from different points of view. 

First up will be a discussion about how technology evolves in the water sector. Two articles will address technology adoption. In one, the author lays out a methodology and approach to building a model and theory about the rate of technology innovation and diffusion. The article describes a four-step process for using past events and current knowledge for companies to understand and predict what might come next. 

Another article will describe what utilities need to know to be smart about how they apply innovation. With new technologies enabling facilities to do more with less and shift away from waste management and toward resource recovery, knowing where to look for new opportunities, how to assess them critically, and when to leap are essential skills. 

The September issue also will explore boundaries of using models. Two features on modeling will examine the topic from different places on the spectrum. One will look at how integrated modeling improves water quality outcomes and reduces utility risks and costs. This article communicates how integrating many types of models — facility, collection system, watershed, stormwater — into a cohesive whole can help assess how changes in one area can affect another. Another article goes in the opposite direction, to adapt design and expansion models into tools for operations teams. The article presents the challenges of adapting and using design models for operations, as well as solutions that some early adopters have discovered. Several case studies put into action the suggestions and steps offered to readers. 


Also in this issue    

  • What’s in a name? A utility rebrands to help customers better understand its role, its challenges, and the logic behind rates.   
  • New Orleans rising. A decade after Hurricane Katrina, the Greater New Orleans area boasts stronger flood defenses, enabling the low-lying region to reevaluate how it manages stormwater.   
  • Upping the ante. Wipes manufacturers face lawsuits and other penalties for allegedly false claims of flushable wipes.
