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.
Water in, water out
The soft drink industry is filled with creative and innovative professionals. They have spurred the development of, and quickly adapted to, technological advances that have made the industry more efficient, profitable, and flexible. Glass is not an effective package? We can use aluminum or plastic. Plastic is too permeable for certain products? Use barrier layers. Sucrose is too expensive? Consider high-fructose corn syrup or many non-nutritive sweeteners. Labor costs are prohibitive? There are robotics.
Yet with all the advances, water is one thing that the industry cannot substitute.
A consolidation of power
The Water Pollution Control Laboratory at the Bureau of Environmental Services of the City of Portland (Ore.) is a mid-sized municipal laboratory tasked with analyzing water, wastewater, stormwater, biosolids, sediments, and soils for the city and other regional municipal authorities.
As the lab has evolved, so has it power requirements – especially in terms of uninterruptible power for sensitive equipment. Read more
Resilient in more ways than one
Exploring how resiliency goes beyond water supply and infrastructure
When the water sector refers to resiliency, what usually comes to mind is maintaining a sustainable water supply through water conservation, water reuse, and the building and maintenance of infrastructure used to protect water resources. The sector has been very proactive in communicating this message of water resiliency to the public.
But what’s given less public attention is that resiliency encompasses much more than just a utility’s water supply and infrastructure. It also refers to the resiliency of the organization itself — from its workforce to its financial stability.
To be more resilient, many utilities are adapting their organizations in response to the evolving global environment. Whether those fluctuations relate to an aging workforce or economy, the hope is to make utilities the strongest organizations possible, capable of weathering storms of any nature.

Pinpointing the problems
Water systems are complex. Hydraulics, chemistry, biology, and mathematics (in many, many different guises) all combine to ensure the right amount of water of the right quality gets to where it’s supposed to go at the right time. Missteps in any of these disciplines can cause either quantity or quality problems.
Often the crucial element to preventing or fixing a problem is a piece of equipment or process step far removed in distance and time. The skill and art of finding the right place to put the right solution is a valuable talent within the water sector.
One case in point is the influent pump station at the Dallas Water Utilities Central Wastewater Treatment Plant. The operators and designers needed to increase its capacity to prevent collection system surcharging. But that was just beginning. They also took the opportunity to do a better job at treating the screenings removed, controlling odors, and minimizing maintenance needs, adding extra capacity to support impending further upgrades.
On the reuse front, two California utilities — one wastewater, one drinking water — joined forces to find the cause of a pollutant of concern. Secondary effluent from wastewater treatment feeds the advanced treatment processes that reclaim the water for aquifer recharge. When elevated concentrations of n-nitrosodimethylamine — an undesired and regulated pollutant in drinking water — appeared in the secondary effluent, the agencies found and fixed the cause. While the level of n-nitrosodimethylamine in the finished water always remained in regulatory compliance, the two agencies found the ultimate cause and put in place procedures to prevent this chemical from reaching the advanced water reclamation process.
