The term “carbon footprint” has been on everyone’s lips since the start of the climate change discussion. Very few industries can claim that they play no part in impacting the carbon footprint — either for good or bad. This is also true for the water and wastewater industry that will have to take a closer look at increasing the efficiency of their facilities to reduce their carbon footprint.
Having to repair old, worn, broken, or leaking pipes is bad enough. Having to revisit the repair location a second time to refurbish the original fix is doubly frustrating. Here are some guidelines for getting the best results from pipeline repair efforts and enhancing the durability of the repair effort to match the anticipated service life of the pipeline itself.
Warming weather can be a cause for concern at drinking water utilities around the country where summer temperatures mean the return of toxic algal blooms.
When developers of a condominium complex sourced wastewater treatment systems, it did so with two primary requirements: efficient land utilization and high effluent quality to meet stringent guidelines. State regulators advised the developers to discuss combining its wastewater system with the owner’s association of an adjacent housing development, whose existing wastewater treatment system was aging and required augmentation.
Environmental Health Assessments (EHAs) are used to better understand the range of possible effects of environmental factors on a community’s health and wellbeing. These assessments are defined by EPA researchers as “methodical evaluations of air, water, and soil pollution impacts on human health and the environment.”
Americans should feel confident that the water delivered to their homes by a public water system is safe to drink. But when residents of Martin County, Kentucky turn on their taps, the water may be discolored, smell like bleach, and make children itch after bathing.
In the face of rising sea levels, structures near source water bodies are increasingly under threat of flood damage. Now, an ambitious plan in Washington, D.C. will be the first of its kind to take major steps to protect against that danger.
As with any industrial process, the right tool for the job depends on the nature of the task at hand. In aerobic wastewater treatment, that optimal choice often comes down to a balance between the biological and financial demands of the application. Either way, here are several performance comparisons of how multiple aeration methods and locations stack up in industrial wastewater treatment applications.
Aeration for industrial and municipal wastewater treatment involves more than simply moving volumes of air through a treatment basin. It really comes down to creating and sustaining an optimal oxygenated environment for microorganisms to convert oxygen consuming compounds into CO2 and water. Here are some key considerations for making better retrofit decisions about upgrading existing basin capacity and efficiency with jet aeration.
In water and wastewater operations, optimizing energy use plays a huge role in cost efficiency, but how can you know if pumping equipment and other motors are running as efficiently as possible? Analytics systems that interpret performance from a variety of data points — pump curves, run time, flow rates, vibration, temperature, energy consumption, etc. — can quantify pump operation to keep performance efficiency on an upward track.
The same scenario plays out daily at water utilities across the country. Water pressure begins to drop during morning hours as customers wake to prepare for their day. As demand decreases throughout the evening hours, system pressures creep up, hitting their highest levels in the early morning hours. This often leads to main breaks. Advanced control valves can be engineered to address this as well as many other problems faced by distribution system managers.
Unlike most municipal wastewater treatment plant (WWTP) applications, industrial wastewater can vary widely from one application to another, even within the same plant, depending on the process being run. Industrial wastewater professionals — especially those facing specific challenges or planned volume increases — can benefit from comparing key points of differentiation in jet aeration system options before making any upgrade.
A maintenance check turned surprisingly grim last week at a Birmingham Water Works facility in Alabama.
The biggest obstacle to investing in natural infrastructure, such as wetlands and reefs, often is that experts have not figured out how to value the protection that these habitats provide in economic terms. But a new report, published by the U.S. Geological Survey’s Coastal Hazards Program, solves that problem for one of our planet’s most biodiverse ecosystems: coral reefs.
Across America, our infrastructure is often failing to deliver, giving way to a growing consensus that more investment is a good idea. Economists tend to be more specific, with particular emphasis on the economic returns from maintenance spending. As the country debates the next great wave of infrastructure investment, it’s important to take stock of spending patterns from the recent past.
In today’s competitive business environment, which focuses on increased throughput, economies of scale and a healthy bottom line, accurate and reliable measurement is a key component. Monitoring production processes by installing a wide range of sensors including flow, level, temperature, and pressure is common and crucial to be competitive. Although there are many reasons why plant managers decide to install monitoring devices in their process, environmental and regulatory reasons dominate one side of the spectrum, whereas quality, process control and monitoring govern the other.
The Frisco Bay Marina at Dillon Reservoir will be safer for boaters and look a lot different this summer, following a massive makeover during the spring months that Denver Water helped pay for.
The hardest aspects of comparing efficiencies among submerged aeration technologies are the many variables in capital expense (CAPEX), operating expense (OPEX), and complexity of wastewater makeup. Instead, consider comparing the physics of different aeration technologies and the relative costs associated with them. Here are five major categories for evaluating industrial wastewater aeration efficiency.
This month, Pennsylvania will begin sampling more than 350 public water systems in an effort mandated by the Department of Environmental Protection (DEP) to curb per- and polyfluoroalkyl substance (PFAS) contamination.

Control of dissolved organics has been one of the highest priority concerns for most water treatment plants for over 20 years. Organics monitoring is an even more critical issue today in the face of more stringent regulations and concerns around trace organics, emerging contaminants, and even counter-terrorism or water security. Despite the critical need, many plants still rely primarily on turbidity for monitoring and process control.
A car struck a fire hydrant in the middle of the night in California, creating a massive water leak. Even before first responders were notified, a pressure sensor sent a text alert to the water utility manager, who was able to dispatch a crew to the scene within minutes. What’s significant is that the utility responded long before receiving a call from emergency crews or an alert from its SCADA system installed in a nearby pump station.
Fewer things are more aggravating to commuters than being told they’ll need to take a detour because of a water main break. Those breaks also leave water utilities with a hefty, unplanned bill. Smart fire hydrants, however, offer water managers the ability to get ahead of these problems by providing more insight than ever into their distribution systems.
Air release valves play a critical role in maintaining pipeline integrity, but most don’t seal properly at lower pressures without changing to a softer seat, when the system is most at risk. The key to avoiding problems, while achieving optimal performance, is selecting air release valves that work in low- and high-pressure applications. The good news is that there are some advanced valve products on the market that seal over a much wider range.
Though the elephant in the room (Texas v.

Fortunately, versatile analytical systems that capitalize on existing wastewater collection infrastructure hold promise for avoiding such negative impacts.
A combination of water scarcity and the desire to provide exceptional service has driven water utility managers to be focused more than ever on acquiring accurate, real-time insight into their distribution systems. Operators face a natural hurdle, however, when using traditional center-line electromagnetic flow meters, which don’t account for velocities that vary across a pipe. Fortunately, a solution has emerged to address the issue.
Nestled in the Finger Lakes region in upstate New York, the town of Owasco is a popular vacation spot. With about 4,000 residents, the town, along with the nearby community of Auburn, relies on Owasco Lake for its drinking water.
