Denver Water serves 1.4 million people in the city of Denver and the surrounding suburbs. It is the largest – and oldest – water utility in the state of Colorado and its service area covers more than 335 square miles.
With the bulk of a pressure-boosting pump’s total lifecycle cost being dedicated to energy and maintenance, it is easy to see why making the right investments in pump hardware and operation can have such a profound impact on ROI. Here are several key points to consider when evaluating ways to get better results from an investment in pressure-boosting performance.
It is no secret that a large portion of the drinking water infrastructure in the United States is near or past its intended design life. Our nation’s water infrastructure needs an overhaul, and the cost of doing so is climbing rapidly. The American Society of Civil Engineering’s 2017 Infrastructure Report Card graded the nation’s drinking water infrastructure a D. According to the American Water Works Association, an estimated $1 trillion is necessary to maintain and expand drinking water service to meet demands over the next 25 years.
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.
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.
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.
Are your current pressure-boosting pumps the best design for your operating conditions? Are they maximizing value from your operating budget with peak efficiency? How can you know for sure, and what can you do if they are not? Here are some guidelines for evaluating performance efficiency in pressure-boosting applications and for choosing the best pump configurations for new or existing applications.
In water testing, readings that we believe to be reliable indicators are not always what they seem. Water that exhibits certain chemical or electrical characteristics at laboratory temperatures can provide entirely different readings in the field. Here is a quick review of what to look for in common water tests and why to consider automatic temperature compensation in the instruments used to collect them.
There’s a big difference between pipe and a true piping system, according to Brian LaBelle of GF Piping Systems. His insights from this Water Talk interview captured at ACE19 in Denver highlight the advantages of ever-advancing plastic piping capabilities that are helping the water industry engineer and fabricate resilient alternatives to aging infrastructure by using customized polyethylene, polypropylene, and PVDF piping systems.
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.
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.
The U.S. House has approved an amendment to the annual defense spending bill that would target per- and polyfluoroalkyl substances (PFAS).
Technology is on pace to reach a milestone of 26 billion devices connected through the Internet of Things (IoT) by the end of 2019. In the water industry, IoT capabilities are enabling utilities to leverage meter reading data collected via secure private cellular networks to satisfy multiple purposes — increasing its value exponentially. In this Water Talk interview, Kristie Anderson from Badger Meter discusses how advances in smart solutions, smart water, and smart city technology are delivering real-world benefits that seemed like futuristic promises just a few short years ago.
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.
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.
Authorities are investigating a tragic incident that led to the death of two sewer workers in Aldan, Pennsylvania.
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.
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.
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.
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.
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.
Many owners and operators of traditional decentralized municipal wastewater treatment plants, also referred to as on-site or off-grid treatment, are acutely aware their systems are at risk of becoming obsolete.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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 quality testing equipment sales roughly equated US$ 3.4 Bn in 2018. According to a new analytical study, sales of water quality testing equipment will surge at a healthy CAGR of more than 5.5% during the projection period, 2018-2027.
