Water 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.

Sharing the risk
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).
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
Membranes for the masses
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.
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
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.
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.
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.
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.
