An environmental research group with a penchant for uncovering widespread drinking water contamination has released a report pointing to a surprising toxin.
An influential leader in the water utility space is stepping down.
Heber Springs, a resort town in northcentral Arkansas, had been experiencing various challenges for a number of years. The utility’s team was facing difficulties in finding qualified personnel to obtain accurate and timely meter readings, identifying leaks quickly due to inaccurate or old meters, and managing extra time spent on misreads and rechecking meter reads. Read the full case to determine how the utility realized that that Badger Meter’s solution would be more cost effective in the long-term compared with other major metering companies.
Air stripping technology effectively removes VOCs, THMs, and CO2 for improved adherence to water quality regulations.
In 2015, wildfire burned over 10 million acres of land across the United States for the first time in recorded history. This was no anomaly: 9 of the 10 worst fire seasons have all occurred since 2000.

I think that in this day and age, everyone knows a variety of ways to conserve at least a little bit of energy and save money while doing so. This is true at home, and across any industry. Take for instance the energy consumption across the United States just in the water treatment process. With thousands of water public utilities across the nation, the amount of energy usage is significant enough to make the statistical charts.
With increasing requirements for enhanced nutrient removal, many wastewater plants are adding anoxic and/or anaerobic tanks in their secondary treatment systems. There are multiple options for enhanced nutrient removal including, but not limited to, the A2O (Anaerobic, Anoxic, Aerobic) process, the UCT or MUCT (Modified University of Cape Town) process and the Bardenpho process.

For several days after floodwaters from Hurricane Harvey inundated the City of Beaumont, TX, the city’s 120,000 residents lost water service when several main water intake pumps fell victim to the flood. Beaumont and other cities in the path of Hurricanes Harvey and Irma, from Texas to Florida to the Carolinas, are experiencing similar fates with sewage treatment plants, flood control systems, and other water-related facilities. When the water recedes and damages are assessed, water facilities that were already strained (many more than 50 years old) will require replacement or extensive repairs
Traditional municipal wastewater treatment plants typically rely on conventional tests such as Total Suspended Solids (TSS) and possibly Volatile Suspended Solids (VSS) to attempt to quantify biomass.
Fairmont, Minnesota, known as the City of Lakes, is located in Martin County in southern Minnesota. The city’s water treatment plant serves a mix of customers including approximately 3,900 residential taps, 500 commercial and 17 industrial customers. Looking to the future, Fairmont city leaders began to investigate upgrading the city’s water treatment plant in 2010. The existing plant had been in operation for well over 70 years and relied on gas chlorine for disinfection.
From Nevada to South Dakota and now Tennessee, cities across the U.S. are installing the AMERICAN Flow Control® ALPHA restrained joint, because it saves labor, time and money. Introduced almost a year ago, ALPHA is used on AMERICAN’s Series 2500 4- to 12-inch Resilient Wedge Gate Valves and American-Darling and Waterous fire hydrants.

Few catastrophes can be as devastating to drinking water supplies as a chemical spill. A utility serving Southern Virginia has developed a plan for responding to such events, which may serve as a model for others.
Those charged with treating our drinking water and wastewater are likely to share the sentiment that they are asked to do too much with too few resources.
Already widespread, nitrogen contamination of environmental waters is on the rise, according to a major study published this summer in the journal Science.
Budgetary constraints and the challenges of maintaining and upgrading aging infrastructure have water utilities looking for ways to operate more efficiently, even as customer service expectations and regulatory demand for more sophisticated reporting and usage information are on the rise. Fortunately, many water treatment plants have found a solution to these seemingly contradictory requirements in remote monitoring systems, which allow utilities to conserve water, operate efficiently, and ensure that the assets within their network are performing well.

Water from cooling towers attracts and absorbs airborne contaminants on a continuous basis. Typically, 85% of suspended solids in cooling water and hot water loops are smaller than 5 microns. Scientific studies have shown that these small particles (5 microns and less) are the adherent contaminants fouling the water loop and process cooling system.
Treatment processes at a wastewater plant in California hit a snag recently when the facility was inundated with salt.
Another community appears to be struggling with a drinking water contaminant that continues to plague treatment facilities around the country.
Water hardness can wreak havoc on your boilers, creating holes in tubes, eating away at the walls. To keep the hardness at bay, you’re going to need to monitor the levels of calcium and magnesium seeping into your system. There are things you need to know to ensure that you are doing this properly. First, use an automated system to increase reaction time to hardness. Next, monitor the softeners; they are critical in keeping the system functioning. Last, learn the temperament of your individual boiler; no two are alike.
The Ecomuseum Zoo is home to the most impressive ambassadors of Quebec’s wildlife. All residents of the Ecomuseum Zoo are there for a special reason: orphaned, injured or born under professional human care, each of them could not return to the wild. Hence, they have found a forever home at the zoo.
Toward the end of the 1980s, Professor Kazuo Yamamoto from Tokyo University gave a lecture to a skeptical crowd. His topic? Immersed hollow fiber membrane bioreactors. Since the day that first audience listened to the possibilities of MBRs, much work has been done to make membrane bioreactors a common step in the wastewater treatment process.
Membrane bioreactor (MBR) plants are found all around the world, serving as a go-to method for treating wastewater through a combination of processes. But as this technology gains popularity, operations must contend with the inherent aeration problems it presents.
Just about a year ago I posted a blog that addressed a disturbing trend — thieves impersonating water and other utility workers to gain access to individuals’ homes and credit card information. Discouragingly, this type of criminal activity seems to be growing and “scammers” are getting more sophisticated in their methods for victimizing unsuspecting utility customers. However, there has also been a very encouraging development over the past year as well, that being the formation and growth of Utilities United against Scams (UUAS).
Since chlorine technology was first used to disinfect drinking water in Jersey City, NJ, in 1908, most waterborne diseases have been eliminated in the U.S. Chlorine is still the most common disinfectant for drinking water and wastewater. Chlorine is also used for disinfection and as a biocide in numerous industries.

Recreational ponds, wastewater lagoons, fish grow-out ponds and small, shallow lakes have always exhibited the problem of organic matter collecting on the bottom and eventually becoming polluted. Wastewater lagoons are especially fraught with problems because their purpose is to clean the wastewater to the point that it can be released back into the environment. Over the years many different things have been attempted to assist in degrading the organic matter that builds up in the “sludge” on the bottom of these water bodies.
