The dry spell in Tennessee has utility officials looking for ways to secure their supplies in case the conditions persist.
It’s still scarf and mitten season in New Jersey, but water utilities are already preparing for a difficult challenge on the horizon: the summer months.
In the San Francisco Bay Area, a fight over water rates has flared up and it’s a clash of millionaires versus local political officials.
With few exceptions, direct potable reuse (DPR) has not been adopted by U.S. water suppliers yet, besides tiny regions of Texas that relied on this water recycling method to survive the recent drought. Several states, including California, are still working on regulatory changes that would make this technology permissible.
In an effort that is opposed by water companies, Connecticut regulators are trying to restrict water exports in the drought-plagued state.
Water reductions at a major California reservoir have left some ratepayers with “nasty-tasting” water.

Known as “produced water,” wastewater from oil production is being used to irrigate crops across 95,000 acres of California’s Central Valley, where many of the country’s fruits and vegetables are grown.
The so-called “water war” trial over whether Florida and Georgia are sharing water fairly wrapped up at a court in Maine last week, and now both sides are waiting to hear what happens next.
Drought conditions in parts of the world not normally thought of as arid continue to worsen. For example, in northern and central sections of New Jersey, drought conditions persist due to lack of rain.
California may construct the largest reservoir it has built since the 1970s in a town outside Sacramento.
Lake Cachuma, a reservoir built to hold Santa Barbara County’s drinking water, is experiencing some problems during California’s historic drought. This past summer, the reservoir reached an all-time low at 7 percent capacity, leaving a thick beige watermark that circles the hills.
Located in Northern Missouri, the city of Trenton and its more than 6,000 residents pride themselves on self‐sufficiency and pragmatic decision making. During the spring of 2012, the utility embarked on the design and construction of chemical feed system upgrades at the existing water plant that would help the city manage the need for new capacity, better control of trihalomethanes (THM’s) and improve operator safety by removing gaseous chlorine as a disinfectant.
The lead contamination crisis in Flint, MI, brought more attention to the country’s piping systems than we’ve seen in a long time. Average Americans were questioning what exactly constitutes the water infrastructure below them and what that might mean for the water they enjoy in their homes.
Oleon NV is one of the leading producers of oleochemicals since the 1950s and specializes in converting natural fats and oils into a wide range of oleochemical products, such as fatty acids, glycerine, esters, dimers, technical oils, specialty oleochemicals and biodiesel. All the products, made from renewable raw materials, combine high performance with ready biodegradability
Leakage is one of the primary concerns for water utilities worldwide, yet North American investment in water loss has, historically, not addressed the problem with sufficient urgency or expertise. Slowly, the regulatory lag to efficiently control leakage is beginning to shift, however.
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.
Eastern Municipal Water District (EMWD) serves about 142,000 customers in Riverside County, CA. The EMWD service area is one of the largest for any water district in arid southern California. On the drinking water side, EMWD manages two water treatment plants and over 15 reservoirs. With 70% of the district’s water coming from the Metropolitan Water District with chloramine disinfection, EMWD has become reliant on chloramine disinfection to manage long transmission lines and longer detention times.
Dissolved air flotation systems are ideal for removing suspended solids and emulsified oils from industrial wastewater streams because they work at high flows and can process high concentrations of contaminants. As Richard Newman, Director of Sales for SUEZ’s Gulf Coast Services, points out in this Water Online Radio interview, the treatment system is ideal for refineries and pulp and paper plants where suspended solids are not water soluble but emulsified.
I’ve had the opportunity to speak and visit with many prospective and current industrial water customers about the technical merits of LuminUltra’s 2nd generation ATP technology, and invariably the conversation always apexes to one critical question – ‘How much does your test cost?’
A plant’s headworks plays a crucial role in the pretreatment influent for any wastewater treatment facility. They protect the operation of downstream equipment and enhance the efficiency of the overall wastewater treatment process.
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.
At my household, a new year means a new energy and water-use baseline. By that I mean, every month, I look at how much electricity and water I used in comparison to the same month the previous year — so I can try to be as efficient as possible. But I work in the energy field, and I know that’s not a typical New Year’s tradition. Most people don’t examine the trends of their energy-use or spend much time thinking about how to reduce it.
As water scarcity continues to be a major, ongoing challenge in the U.S., public and private sector leaders are seeking new insights on sustainable solutions. In this work, they are grappling with challenges on a scale that oil and gas organizations have been confronting for decades now. It’s understandable that stakeholders can get caught up in the tactical side of dealing with water crises — but there is also guidance to be gained by taking a high-level view.
When you prepare the Thanksgiving meal, do you ask each person to make a dish of their choosing, with no coordination for an overall cohesive meal? Probably not. Most likely, you plan, because you want everything to fit together.
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?
There have been many publications lately that claim universal appeal of the ORP sensors and their applicability across the board. This concerns me, because the authors sometimes forget to mention some well-known practical limitations of the method, let alone the realities of water treatment applications potentially influencing the sensor performance.
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 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.
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.
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?
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.
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.
