Nobody wants to think about the worst case scenario but if you’re responsible for water treatment at an industrial plant, you can’t avoid it. There are any number of things that can force a plant to go offline and it’s imperative that a contingency plan is in place for such an event. Luckily, there are mobile equipment suppliers that can keep things running during an outage, planned or otherwise. Water Online spoke with one provider of such a service, Evoqua Water Technologies, about how it keeps plants running no matter what.
Collectively in the municipal wastewater treatment industry there exists a tremendous knowledge base. Among those who are actively engaging in the trade, a resource of innovative skill sets is potentially accessible through many of the individuals’ experiences and discoveries. The challenge is: How can these people work together effectively to benefit from this state-of-the-art resource?
Those in the water industry know water is essential for life and brings economic value, but the economic role of water is often not as well understood by the general public. This paper reviews the history and development of our transportation, electrical, and energy infrastructure and then presents a plan for our nation’s water to be augmented from where we have it abundantly to where we badly need it.
Daryl Weatherup, Director of Marketing for Evoqua’s Wallace & Tiernan brand, recently sat down with Water Online Radio to discuss disinfection management, residuals, dosing, disinfection byproducts (DBPs), chlorination and the latest technological advancements being announced at ACE16, including Evoqua’s acquisition of UV disinfection provider Neptune Benson.

In a time of pervasive drought throughout the Western United States, combined with the relatively newfound ability to account for every ounce of water treated and distributed, it’s no surprise that huge emphasis has been placed on smart, data-savvy metering.
World Water Day was March 22. National Groundwater Week was just completed. These two events are especially timely as generationally significant droughts are in the news. Texas and California, two of our most populous and economically vibrant states, are experiencing drought not seen in the careers of today’s water and municipal professionals.
You may have heard about the tragedy in Flint, Michigan — but to keep everyone on the same page the water in that system has turned toxic.
Carollo Engineers unveils an ambitious plan to turn one of America’s most water-stressed cities into a model of sustainability and resiliency.
In our series on the Smart Grid for Water, we continue to build on the theme that the Smart Grid for Water is free. As we have seen, starting with the meter-to-customer vision, the deployment of an entirely new AMI, highly functioning tools, and customer engagement platforms can be financed entirely within existing budgets.
In 2002, a catastrophic wildfire that burned 138,000 acres of forest made Denver’s drinking water supply run black with ash and soil. Cleanup of infrastructure damage, debris and erosion cost more than $25 million, while the fire-ravaged landscape caused increased flooding that wreaked havoc on water infrastructure and roads for years.
Of all the industries my colleagues and I work in, some of the steepest challenges we see are in the water sector. As Water Online readers well know, scarcity now looms larger than ever in the U.S., with water organizations constantly confronting issues ranging from dwindling supplies to aging infrastructure, chemical contamination, and limited financial resources.
Are environmental interests and business interests mutually exclusive? Our divisive sociopolitical climate might make you think so — you’re either labeled ‘tree-hugging’ or ‘greedy’ — but it is not an either/or proposition, especially when it comes to water conservation.
About 50 percent of the nation’s residents source their fresh water supply from groundwater wells, which have deteriorated throughout the U.S. over the past decade. For shallow wells, severe drought conditions have gradually depleted groundwater levels.
Yes, America cleaned up at the Olympics this summer, but how does the U.S. fare on the world stage when it comes to water resiliency, efficiency, and quality?
With large parts of the country facing drought conditions, including California, Massachusetts, and Alabama, small communities and cities alike are facing increased water-energy nexus pressures.
A water technology expert tackles high-profile and important topics currently affecting municipalities, industry, and the community at large.
There are a lot of technology startups in the water space vying for attention, including a good bit in the New England area alone, but one Massachusetts company and its potentially "disruptive innovation" stands apart.
When we humans look at objects we describe them in terms of color. We say that an apple is red or a leaf is green. To us color is an attribute just as surely as the mass or dimensions of an object. But the fact is that color is a pure human construct. Take away the human and it does not exist.
For water treatment operators and utility officials, the summer months don’t just mean sunshine, pool parties, and barbecues. The season also brings the peak time for algal blooms, the toxic clouds formed in surface water thanks to increased nutrient contamination and rising temperatures. With rising instances of toxic algae around the country and increased regulations for eliminating it, utilities have had to keep pace.
A metallically-pure, stress-free surface provides optimum corrosion protection for wastewater treatment plants. Here’s how to get there.
When Flint Michigan discontinued purchasing water from the Detroit Water Authority and began using the Flint River as their raw water source they unfortunately did not consider the potential impact on lead and copper corrosion and the impact on the public.
High levels of radionuclides (uranium/radium/etc.) in drinking water aren’t very common, but they are very dangerous. If you’ve long dealt with radionuclides, you’re familiar with the treatment requirements — but are you treating as cost effectively as possible?
When is the last time you took a moment to stop, and smell your water? A continuous supply of clean and safe drinking water is something that most people take for granted. We rarely go to the tap doubting that the water will be clean and safe. Recently, the general population and water supply professionals have become concerned about the safety and protection of our drinking water supplies.
We all hope that the Flint Water Crisis – where cost-cutting measures led to the drinking water supply to become severely tainted with lead – was an isolated incident. However, it is not impossible that a similar event could happen again, especially in a similarly desperate city with limited financial resources. Here are a few key points that should be considered to avoid repeating such a tragedy.
Chemical, petrochemical, and oil-reﬁning plants are process-intensive operations with regulatory requirements to protect the surrounding water and air from the effects of industrial pollution. These external demands are matched by equally compelling internal pressures to address product puriﬁcation needs, ﬁnd alternatives to utilizing costly fresh water in production processes, reduce the carbon footprint, and operate efficiently and proﬁtably.
The U.S. EPA’s Long Term 2 Enhanced Surface Water Treatment Rule (LT2) was adopted in 2006 to modify the Safe Drinking Water Act and more tightly control the spread of Cryptosporidium, a microorganism that can cause gastrointestinal infection if ingested. Since its inception, the rule has posed a treatment challenge to utilities that are susceptible to the tiny contaminant. But which utilities are at risk? And how should they approach treatment?
The world has watched this summer as countless customers in Detroit have had their water shut off due to nonpayment.
