    Water resource recovery facilities (WRRFs) are already aware of the idea that biosolids can be a valuable commodity. Consequently, there is opportunity to grow this market. The use of biosolids can create products that have value and generate a customer demand that ultimately leads to an economic incentive for WRRFs. There are several factors that contribute to the success of biosolid products, like the quality of biosolids and information available about how and where to use high quality biosolids.

  • Avoiding The Pitfalls Of Capital Projects
    Avoiding The Pitfalls Of Capital Projects

    When it comes to big projects, often part of a municipality's capital improvement plan (CIP), it's the planning part that is too often overlooked, or simply not well executed. This causes a number of problems during implementation — problems that can increase risk, waste time and money, and degrade project outcomes. In this Water Talk interview, James Strayer of Black & Veatch describes the typical problems capital programs encounter and explains how proper planning and asset management can help improve project success rates.

  • Irrigation Consumer Bill of Rights: Smart Irrigation Starts With Smart Choices
    Irrigation Consumer Bill of Rights: Smart Irrigation Starts With Smart Choices

    As we celebrate Smart Irrigation Month, it's a great time to highlight not only smart technologies, but the smart people and smart decisions behind them. One remarkably smart tool that ties all three of those elements together is the Irrigation Consumer Bill of Rights by Dr. Charles Burt of the Irrigation Training and Research Center (ITRC) at the California Polytechnic State University (Cal Poly) in San Luis Obispo.

    Advanced technology and more widespread acceptance are driving a growing number of municipalities to adopt the practice of wastewater reuse. Ultrafiltration (UF) has been proven a key in this process, but operators have struggled to keep up with repairs or having to replace older hollow-fiber membranes. Recent advancements in manufacturing have produced more durable membranes that accomplish the task at a lower cost based on the total lifecycle.

  • Climate Change And Nutrients: Forewarned Is Forearmed

    Rising temperatures and precipitation combined with increasing nutrient runoff from human activity are elevating challenges in water treatment efforts. In some cases, that means increased threats to drinking water quality. In others, it means increasingly stringent nutrient discharge levels. Either way, taking the nutrient monitoring battle out to the field can help in waging a better fight at the treatment plant.

  • Despite Potential Trump Veto, PFAS Amendment Passes House

    The U.S. House has approved an amendment to the annual defense spending bill that would target per- and polyfluoroalkyl substances (PFAS).

  • Leveraging Water Data: The Future Is Here!

    Technology is on pace to reach a milestone of 26 billion devices connected through the Internet of Things (IoT) by the end of 2019.

  • WWEMA Window: In Memory Of Bridget O’Grady (7/11/1949 – 7/9/2019)

    This month I would like to celebrate and honor a dear colleague and friend who recently lost a short but heroic battle with cancer. Bridget O’Grady was just two days shy of her 70th birthday — the date that she had set for retirement. What makes Bridget remarkable is that much of her life and career was dedicated to making drinking water safe and secure for all of us; and she worked to the end to make that a reality.

  • Defending Against Saltwater Intrusion

    Are “ghost forests” a sign of things to come? Rising sea levels and superstorm tidal surges are already impacting coastal areas, with rising salinity levels affecting some drinking water sources. Coastal water utilities are not the only ones that have to worry about salinity, however, as high concentrations of winter storm road treatments, gas drilling, and mining can also generate elevated salinity levels in surface water sources.

  • Sewer Workers Killed While Conducting Dye Test

    Authorities are investigating a tragic incident that led to the death of two sewer workers in Aldan, Pennsylvania.

  • Total Dissolved Solids: A Matter Of More Than Just Good Taste

    Everyone wants good-tasting water, but most water treatment plants (WTPs) are hostages to the composition of their local source water supplies. One of the components involved in taste is total dissolved solids (TDS), which can affect both the acceptability of finished water taste and its likelihood to corrode or clog pipes and fixtures. Here’s how to quantify the problem and what to do about it if it is excessive.

  • Modern Metering Adoption At Smaller Public Water Systems

    As with most things in life, there are those water utilities that have and those that don’t. According to the EPA, less than 3% of the 150,110 operational public water systems (PWS) in the U.S. serve more than 10,000 people. And those 4,500 systems serve 79% of the population. Not that being big means living trouble free. Many of these water authorities serve cities plagued by under investment over decades in their water systems. And yet with large rate-bases comes the means to spread the investment in modern technology across many households and water consumers.   

  • A More Precise Route For Chemical Feed Metering

    In water treatment applications with varying flow rates, keeping chemical dosing rates in proportion is critical for minimizing chemical costs while still achieving optimum treatment levels. A new plastic-bodied ultrasound flow meter delivers high precision at extremely low flow rates — down to 0.15 gph (10 ml/minute), about one-third of the 0.50 gph rates offered by most other chemical flow meters.

  • Harnessing Data For Better Maintenance Outcomes

    Using a calendar to determine when maintenance is needed for pumps, blowers, and other equipment no longer gets the job done. That’s because the ability to harness data to drive condition-based maintenance is now available. Understanding how your assets are performing, versus how they should be performing, is a key step towards predictive analytics. In this Water Talk interview, Manuel Parra, business development director for water and wastewater solutions with AVEVA, discusses industrial software for asset performance management that is allowing water managers use data to reduce the cost of their maintenance and extend the life of those critical assets.

  • The Impact Of Company Culture On Your Technology Partner

    There are a variety of technology vendors serving the water and wastewater industry, and many offer products and prices that are very comparable. Sometimes the differentiator comes down to the service, which is driven by company culture. In this Water Talk interview, Rich Cavagnaro, CEO of AdEdge Water Technologies, and Fariha Hassan, a project manager with AdEdge, discuss the positive ways to impact company culture and how that can go a long way toward impacting performance and innovation.

  • Water-Sharing Experiment Suggests People Put Their Own Survival First

    There’s been talk lately about empathy, its components and its general decline. A decline in empathy concerns me as an assistant professor in the University of Saskatchewan’s School of Environment and Sustainability: I study how people cope with water problems or learn to share scarce resources, like water, gas, oil, and energy.

  • Choosing The Right Water Disinfection

    In the mid-to-late 1800s, chlorine had been used sporadically to help control infection in hospitals and drinking water. Common water treatment did not start in the U.S. until the early twentieth century when increasing cases of waterborne illnesses prompted many large cities to begin large scale filtration of water supplies.

  • Lowering The Cost Of Leak Detection

    Aging infrastructure is shaping up to be an enormous burden on municipalities. The next 30 years will require a $1 trillion investment just to keep up with the replacement curve for water distribution pipes. At the same time, leak targeting and physical condition assessment of existing networks is an expensive proposition. In this Water Talk interview, Doug Hatler, chief revenue officer for Fracta, discusses the application of artificial intelligence in advanced screening solutions to bring those evaluation costs down.

  • How Advanced Flow Meters Are Changing The Game For Water Managers

    Flow meters are not just hardware anymore. Advanced flow meters act as a data collection tool that can gather and relay valuable information for engineers and technicians trying to be more proactive in the operation of their water systems. In this Water Talk interview, Dave Baker, a regional sales manager for McCrometer, discusses advanced flow meter capabilities that are more user friendly as well as the importance of selecting the proper meter for specific applications.

  • Easing The Burden On Water Plant Operators

    The goal of water plant operators is almost universal: to ensure they're providing quality water to customers while detecting leaks, running at optimal energy usage, and maintaining systems. The problem is traditional controls and SCADA systems have gotten so complex they can actually make the job more difficult. In this Water Talk interview, Malcolm Thompson, the chief financial officer of XIO, and Kevin Liscovitz, the chief operating officer of XIO, discuss newer technology making water plant controls as simple as possible for operators while providing better insight into asset management.

  • Solutions To Remote Data Entry In SCADA

    A watershed isn’t typically tied into a water system’s SCADA system, but students and others observing the health of the resources may have information that can be of great value to plant operators. This is just one example of when there is a need to enter remote manual data into a SCADA system. In this Water Talk interview, Dave Spencer, technical sales with VTScada from Trihedral Engineering, discusses advanced technology that promote improved oversight by allowing the transfer of data into, and out of, SCADA systems.

  • 4 Misconceptions Of AOP For Wastewater Treatment

    Advanced oxidation is a rather complex wastewater treatment process. The general concept of how the process works can be difficult to grasp at first, and the number of possible oxidation methods can seem daunting. Therefore, you turn to the internet for information, and try to analyze together all the information you find using various online resources. However, everything doesn’t always fit right, and you come up with ideas that may not be quite true.

  • Combining Biosolids Waste Streams? Not So Fast…

    The idea of combining two systems into one sounds like a common-sense solution to simplifying operations.  Wastewater treatment plant operators have been experimenting with this concept by combining waste activated sludge with primary and septage waste streams with the goal of lowering system complexity.  The reality of these efforts is proving, in many cases, to be problematic.

  • How To Engage Consumers For Smart Water Wins

    Smart water technology, which produces mountains of data, has the potential to improve water system operations and widely impact consumer habits. The latter, however, is only effective if the information is embraced by individuals. In this Water Talk interview, Ian McLeod, vice president of marketing for Master Meter, discusses how a newer method of connecting smart water solutions to a popular tech device will likely boost ratepayer engagement and lead to behavioral changes.

  • Tackling PFAS And Other Emerging Contaminants

    Manmade chemicals — most notably PFAS and 1,2,3-trichloropropane, or TCP — are emerging as a serious threat to water sources that municipalities at some point will need to address to meet regulations and provide quality water. PFAS has been rearing its head across the U.S.; and while TCP is mainly a California issue, it could prove to be more expansive. In this Water Talk interview, Jim Knepper, vice president and general manager of the Resinex division of Jacobi Carbons, and Mike Bickel, a municipal sales manager with Jacobi, discuss how activated carbon technology is helping water plant operators tackle looming problems such as PFAS and TCP.

  • Western States Buy Time With A 7-Year Colorado River Drought Plan, But Face A Hotter, Drier Future

    As Midwest states struggled with record spring flooding this year, the Southwest was wrestling with the opposite problem: not enough water. On May 20, 2019, federal officials and leaders from seven states signed the Colorado River Drought Contingency Plan, a sweeping new water management agreement for this arid region.

  • Using Technology To Get An Edge On Water Loss

    Water loss is a massive problem for municipalities as distribution system leaks, metering inaccuracies, and theft combine to waste an average of 30 percent, or more, of treated product. While progress is being made on the issue — also known as non-revenue water, or NRW — there is still plenty of room for improvement. In this Water Talk interview, Jeff McCracken, a director of operations and management solutions for Itron, discusses advanced technology that digs into data to help locate both the real and apparent losses facing water managers.

  • Sludge Thickeners: The Good, The Bad, And The Smelly

    Management of wastewater sludge is a core responsibility of treatment plant operators. With this responsibility comes common challenges that must be overcome.  These include controlling odors so as to have a minimal impact on the surrounding community and minimizing hauling costs for its disposal.  Getting a handle on both of these responsibilities and more can be much easier with the proper sludge-thickening equipment.

  • A Preemptive Approach To Algal Blooms In Source Water

    The dramatic rise in algal blooms, and increases in other contaminants, has left many municipalities struggling to get a handle on their source water. However, there are effective ways to manage those problems ahead of intake to stabilize the process inside of water treatment plants. In this Water Talk interview, Justin Voty, a marketing and commercialization manager with Innovative Water Care, and Jackie Schramm, a sales manager with Innovative Water Care, discuss the benefits of taking a more preemptive approach to treatment and disinfection. Innovative Water Care, formerly part of Lonza, became a standalone business unit earlier this year.

  • How Continuous Monitoring Helps Systems Grappling With Quality Issues

    As regulations become more stringent and increased demand is putting pressure on sources, traditional sampling to maintain water quality just isn’t cutting it anymore. Relying on periodic samples analyzed in a laboratory means water managers aren’t in touch with potentially large swings in the organic load and other problems flowing into their treatment plants. In this Water Talk interview, Kerim Kollu, an applications research scientist for Real Tech, discussed the emerging technology that is enabling municipalities to reliably perform continuous monitoring.

  • 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.
