Like most digital technology, the move from traditional to smart water meters seems like an inevitable step in the march towards progress. However, due to cost and regulatory concerns, many utilities have yet to make the transition.
The Cheyenne Board of Public Utilities (BOPU) operates the water and wastewater systems for the capital of Wyoming which has a population of more than 63,000. Located in the fast growing Front Range Urban Corridor, BOPU is challenged by growth, periodic water scarcity and aging infrastructure.
Operating a wastewater facility is no easy task in today’s world. There are many challenges that owners / operators face, including sewage composition, water consumption, and an aging infrastructure.
A natural gas-fired combined cycle power generation facility located in Idaho contacted QUA to find a solution to improve the performance of a water treatment system used to recycle the plant’s cooling tower blow down water.
When it came time to design a new wastewater treatment plant for Field, the seasonal rise in population during the summer months added to the challenge of meeting Parks Canada's stringent mountain effluent targets. The goal of the new wastewater treatment plant was to protect this pristine wilderness area by setting the effluent target as close as possible to the natural composition of the receiving water bodies. With this in mind, Parks Canada reviewed the latest in advanced treatment technology and opted for a membrane bioreactor system
Veolia’s CeraMem® Ceramic Membrane Technology was selected as an “Energy Innovation Pioneer” at the 34th Annual CERAWeek energy Conference due to successful installations in the oil & gas industry.
People concerned about their water footprint often make an effort to turn the faucet off quickly, take shorter showers, and cut back on watering the lawn.

To increase capacity within the existing footprint of a wastewater treatment facility in Michigan, two existing tanks were converted to aeration tanks with pure-oxygen aeration provided by Praxair’s In-Situ Oxygenation (I-SOTM) System.
A new project from the Water Research Foundation seeks to determine quality parameters for alternative drinking sources and get utilities that much closer to accessing them.
A new report by the U.S. Chamber of Commerce blasts the U.S. EPA and the Executive Branch for imposing environmental mandates without giving voice or financial consideration to the states’ plight.
A water technology expert tackles high-profile and important topics currently affecting municipalities, industry, and the community at large.
In October, the WateReuse Association’s 2016 Potable Reuse Summit will bring water professionals of all levels together to hear success stories and find out how to implement potable reuse programs in their own communities.
This year's Annual Conference and Exposition (ACE16), held by the American Water Works Association (AWWA) from June 19 to 22, was the first following the tragedy of Flint — a time when the drinking water industry is under intense scrutiny.
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.
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.
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?
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.
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?
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.
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.
The students at the University of Miami will know firsthand the importance of rethinking the way we handle wastewater and water with a Net-Zero water treatment system on site. The project showed the viability and feasibility to take buildings off the water grid to provide water recycling and how it can be achieved without raising the cost of high quality water.
A metallically-pure, stress-free surface provides optimum corrosion protection for wastewater treatment plants. Here’s how to get there.
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.
