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.
Big and bold
The Trinity Watershed Management (TWM) Department of the City of Dallas found the opportunity to pursue a unique project on a massive scale. TWM designed and built a 3.8 billion L/d (1 billion gal/d) stormwater pumping station using a technology rarely seen in the U.S. for flood control — concrete volute pumps (CVPs).
Most aeration systems that use real-time control are based on dissolved oxygen (DO) measurements, but these measurements often are slow to react to changing conditions. New control strategies use predictive parameters that are based on influent wastewater quality as opposed to DO. Real-time ammonia–nitrogen monitoring plays an increasingly important role for successful biological nutrient removal at water resource recovery facilities (WRRFs).
State of the Industry
WE&T’s annual State of the Industry section provides an overview of trends that are likely to grow and develop throughout the coming year. This in-depth section analyses how perceptions about water and wastewater are changing as well as the new practices and conditions that are driving these changes.

It has become part of the holiday tradition of exchanging and opening gifts to then have to put together toys and furniture, hook up wires, and install apps and programs. This chore can cast a shadow of frustration over the last few days of the holidays. Even with the instructions in hand, some more insight into how to complete those tasks would’ve been helpful.
While WE&T can’t help figure out why you had three screws left from assembling the new entertainment center, it can lend additional insights on some other topics. A theme of looking deeper into planning runs through several of the articles in the February issue.
In one case, the author dives deep into energy savings performance contracts. These types of design–build projects for operational efficiency seek to guarantee the outcome before the work even starts. And they’re usually cash-flow positive and, therefore, self-funding.
While many of these types of projects have been successful throughout the U.S., some have faltered. This article will seek to identify the potential pitfalls and provide best practices to make sure that energy savings performance contracts work as intended.
On the grittier side of things, another article will explore the growing science and practice of grit characterization. Using five examples, the article will educate designers and users on the different criteria required for properly sizing grit systems and demonstrate why and when flow velocity and capacity should be emphasized over settling and surface overflow rates generated from traditional sizing methods.
