    White House Utility District Reduces Costs By Over $1 Million

    In 2007, White House Utility District (WHUD), a water utility serving approximately 90,000 consumers and businesses in Tennessee, faced a dilemma: how to meet a projected growing demand for water within the budget and capital constraints faced by municipal and mid-sized utilities everywhere.

  • A 14-Point Checklist For Choosing The Right Water Utility Network
    A 14-Point Checklist For Choosing The Right Water Utility Network

    Mass market access to the internet through a combination of hardwired, Wi-Fi, or cellular communications channels has conditioned many people to think that “a network is a network is a network.” When it comes to water utilities, however, the nature of the application environments and requirements dictate a closer look at how to satisfy the specific requirements most efficiently. Here are 14 checkpoints to consider before selecting a new network option or revamping an old one.

  • Asset Monitoring: Are You Getting Your Money’s Worth?
    Asset Monitoring: Are You Getting Your Money’s Worth?

    Mapping the assets of a water treatment, water distribution, or wastewater collection and treatment system is just the means to an end. Maximizing value from that effort requires systematic planning and a healthy curiosity for looking into patterns of activity. Here are some considerations for turning raw asset data into more valuable benchmarks for better decision-making across multiple aspects of water operations.

  • Australian Cities Adopt Wastewater Reuse
    Australian Cities Adopt Wastewater Reuse

    Potable reuse of wastewater has gone by many different names, some of them unflattering, like “toilet to tap.” Despite the clear benefits of water reuse, this so-called “ick factor” has slowed the adoption of technology that can transform wastewater into drinking water.

  • Effective Solutions For Removing Short-Chain PFAS, GenX, And PFAS Precursors
    Effective Solutions For Removing Short-Chain PFAS, GenX, And PFAS Precursors

    Debate about regulating per- and polyfluoroalkyl substances is heating up across the country as the extent of known contamination continues to grow at an alarming rate. Also known as PFAS, this large group of toxic fluorinated compounds was used widely in industrial and consumer applications. Progressive water utilities are trying to quickly get a handle on the problem to better protect their customers from even further exposure.

  • Wastewater Service Charges Continue To Rise

    Wastewater service charges vary considerably across EPA regions and States. That’s one of the key findings from the National Association of Clean Water Agencies’ (NACWA) Cost of Clean Water Index. If you live in Montana, Wyoming or the Dakotas (EPA Region 8), your average service charge of $261 a year is considerably less than the $884 your fellow Americans up in New England (EPA Region 1) are paying.  As you can imagine, much of the difference is to do with population size and geography.

  • Water Recycling Efficiency In Ethylene Spent Caustic Treatment, Part I: Cost
    Water Recycling Efficiency In Ethylene Spent Caustic Treatment, Part I: Cost

    Handling process byproducts has always been a concern for ethylene producers. When it comes to wastewater treatment, spent caustic has always been the most challenging waste. In water-stressed locations, treating toxic components is not the only factor in achieving wastewater treatment and water recycling goals affordably.

  • How To Save Costs With Simple, Effective Data Management
    How To Save Costs With Simple, Effective Data Management

    Water and wastewater utilities must monitor numerous aspects of their systems on a continuous basis. Various instruments are used to measure these processes, producing volumes of data every day. Endress+Hauser is a leading supplier of products and services for process measurement and automation. Water Online spoke with three of Endress+Hauser's experts to find out how data loggers and managers can save costs while providing effective data management.

  • The Caribbean’s Wastewater Problem
    The Caribbean’s Wastewater Problem

    For decades, wastewater management has been a growing problem for the Wider Caribbean Region (WCR), a problem that regional governments have long understood as a threat to the economy, the environment, and to public health. In the Caribbean, most wastewater from cities, industry, and agriculture pours directly into surface water or into the sea completely untreated, degrading residents’ quality of life, as well as the region’s biodiversity, pristine blue waters, and reefs, which are the lifeblood of the vital tourism industry.

    When I attended the U.S. EPA-hosted PFAS Summit held at the Horsham, PA high school auditorium on July 25, 2018, the education I received from state and municipal leaders focusing on the local problem was more than just a professional briefing. It was ominously personal, due to the fact that the Water Online editorial office where I work and drink water every day is served by a utility sitting smack-dab in the middle of one of the most concentrated PFAS hotspots in the U.S.

  • What Did Rural America Do To Deserve This?

    By now, just about everyone in the U.S. has heard about Flint, Michigan’s water woes. Despite the many issues raised by that incident, urban water systems are not the sole reason the 2017 Report Card from the American Society of Civil Engineers gives the U.S. drinking water infrastructure an overall “D” grade. Hidden within that disheartening rating are the harsh realities faced by rural water systems.

    Orchestrating Corrosion Control With Phosphate Analyzers

    As with so many other drinking water treatment processes, corrosion control demands a delicate balance among multiple factors. From the water-purifying chlorine that increases corrosion risk, to alternative strategies that reduce corrosion — using either elevated pH or phosphates — keeping corrosion under control requires sound strategy and reliable execution. Here are several approaches to addressing those conditions, along with options for better, more effective corrosion control.

  • Calibrating Success: Improved Tools To Maintain Flowmeter Accuracy
    Calibrating Success: Improved Tools To Maintain Flowmeter Accuracy

    Water utilities with highly successful monitoring programs tend to share a common trait: they have a well-defined plan for calibration that emphasizes frequency and tracking. However, when done properly, this process is time-consuming and often leads to unnecessary labor and downtime. The good news is that advanced metering technology is available for plants to get a better handle on the instrument’s performance with significantly less effort.

  • Water Monitoring's Triple Threat: Bad Habits, Bad Readings, Bad Results
    Water Monitoring's Triple Threat: Bad Habits, Bad Readings, Bad Results

    When water and wastewater plant operators can’t get accurate flow measurements or analytical readings — or lack confidence in their instruments’ readings — it creates challenges with the process. When substandard water goes to homes and causes a boil order, or discharge pollutes a lake or reservoir, the resulting bad press, fines, and potential lawsuits erode public confidence. Avoiding these kinds of problems is rooted in good preventive maintenance habits.

  • Bar Screen Capture Rates: It’s Not So Simple
    Bar Screen Capture Rates: It’s Not So Simple

    The water industry has made progress in developing numerical values for screen-capture ratings under specific conditions. One such example is the UK Water Industry Research (UK WIR) standard. Its methodology is sound in measuring capture rate for a specific screen in a channel for a specific time and set of conditions. However, the measurements provided in these studies cannot be assumed to represent the performance of that screen in any other wastewater treatment plant or even in the same channel in a different time or season.

  • Achieving Level Pressure At Challenging Points In Distribution Systems
    Achieving Level Pressure At Challenging Points In Distribution Systems

    When drinking water leaves a treatment plant through giant pipes, with the help of huge pumps, the pressure can exceed 200 psi. The high pressure is a necessity because water must travel a long distance in some cases. Water towers scattered throughout the distribution system aid in the process so it can reach all utility customers. The problem is that not all distribution points in a water system are created equal.
