Utility managers are continually challenged to run water systems in the most efficient manner. Reducing non-revenue water (NRW) is an important component for system efficiency. In many states, regulators are placing caps on NRW or requiring reductions in the amount of NRW. Accurate and well-planned flow measurement can be used to locate areas of water leakage and reduce NRW.
Water utility managers today face a conundrum. The American Water Works Association (AWWA) recommends a water utility strive for non-revenue water loss at 10-15 percent, but managers know that many systems lose as much as 50 percent. Discovering where these losses occur is difficult.
While utilities use sophisticated systems to supply clean water as well as collect and treat wastewater, the effort to manage incidents and outages leaves room for improvement. Water utilities often rely on manual processes to handle customer reports of leaks, loss-of-service or quality issues.
The 2010 Water Stewardship Act enacted by the state of Georgia has accelerated several utilities’ water loss and control programs. Provoked by the Act and the Water Supply Efficient Improvement Plan mandating that “by July 1, 2016, Public water systems shall develop and conduct a water loss control program to investigate, assess, and implement efforts to improve water supply efficiency,” Columbus Water Works (CWW) set out to develop a comprehensive plan for not only meeting, but exceeding the required objectives.
After analyzing annual water loss audits for the city of Dallas, GA, the team discovered significant issues around non-revenue water. In 2014, real and apparent water loss accounted for 31.3 million gallons — nearly 20 percent of the city’s total water supplied for the year — which meant lost revenue for the city.
Situated along the Arkansas River and Lake Dardanelle in the heart of the Arkansas River Valley, Russellville, Arkansas is known for having plentiful amounts of high quality, fresh water.
These days, operators and managers of water treatment plants are losing sleep. Why? Because they may be losing water.
Jalur Cahaya Sdn Bhd (JCSB) is a full-service environmental engineering company that helps Malaysian water utilities reduce non-revenue water (NRW).
Historically, most fire hydrants sit idle after they are installed. They were there for that one day that hopefully never shows up. But in today’s connected world, fire hydrants are becoming an important asset in understanding the water distribution system, allowing utilities to monitor their water system operation and predict leaks.
For those unable to attend, the Internet of Things (IoT) was firmly part of the conversation at this year’s American Water Works Association’s (AWWA) Annual Convention and Exposition (ACE) in Philadelphia. If you haven’t heard the term, you’re going to hear a lot more of it in the years ahead. None more so than in the world of water distribution systems where it can provide real-time reporting to utility managers charged with systems upkeep, maintenance and reliability.
Solving the problem of non-revenue water starts with leak detection. Many utilities live with leaks because of the time, labor, and expense involved in detecting, prioritizing and fixing them.
As water loss continues to concern many utilities, American Leak Detection’s franchise business model continues to “plug many a hole.” As Adam Gray, Director of Marketing for American Leak Detection, explains in this Water Online Radio interview, the franchise model is effective on numerous levels, whether it be providing the leak detection expertise that a utility doesn’t necessarily have on staff or allowing leak detection experts to share their insights and knowledge across the franchise network.
Eric Stacey, Product Manager with Echologics, recently sat down with Water Online Radio to discuss leak detection, pipeline condition assessment, and permanent monitoring. As more and more sensors are put into the water distribution system, utilities are monitoring the formation of leaks and becoming more informed about their water loss.
If A Pipe Leaks In A Forest, Does It Make A Sound? (Part I) addressed condition assessment and leak detection from the perspective of surprises that can arise when “hidden” problems are revealed by acoustic technology. This article introduces several more eye-opening experiences with permanent and mobile acoustic leak detection equipment, plus examples of just how expensive undetected leaks can become when they turn into full-blown water main breaks.
Utility managers are facing increasing financial and sustainability pressures regarding water loss throughout their systems. An American Water Works Association (AWWA) white paper titled The State of Water Loss Control in Drinking Water Utilities notes that “all utilities incur inefficiencies, or losses, in both supply- and customer-related functions of their operations.”
Beyond the existential philosophy implications, the consequences of a pipeline leaking in a forest when no one is around highlight the desirability of leak detection systems in water distribution utilities as a whole. As the following experiences show, leak detection can have its entertaining side. On the other side of the coin, however, the consequences of not monitoring leaks can also trigger a tsunami of costs far beyond the expense of pipeline repair alone.
Despite my fascination with the adage, “The definition of insanity is doing the same thing over and over again, but expecting a different result,” I still occasionally find myself — a creature of habit — falling into a pattern of repetitive unsuccessful behavior.
Smart water networks today do more than read meters. They also collect data from sensors on distribution networks to help reduce non-revenue water losses, monitor and control pressures in water mains, and prevent unwanted sewage discharge. These new smart infrastructure solutions help water utilities expand the definition of smart water — going beyond applications aimed at improving billing accuracy and efficiency.
For many utilities, failing pipelines and non-revenue water are atop the list of concerns. However, these issues can be greatly mitigated by leveraging readily available data in an intelligent way — through smart water management.
Sniffer dogs have been used for a while in the oil and gas industry to find leaks. But recently, dogs have begun to be used to find leaks in water mains.
As water distribution infrastructure ages, the potential for leaks grows and the need for condition-driven asset management increases proportionally. As with so many other aspects of water operations, planning ahead is key. Good system diagnosis using noninvasive procedures provides an accurate and cost-effective assessment of distribution system integrity, just as noninvasive monitoring of heartbeat, pulse, and blood pressure plays an important role in human health.
This video explains how Aquis Leak Detection can reduce the amount of Non-revenue Water by reducing loss of water through existing leaks and reduce the risk of additional leaks. Furthermore energy consumption, emissions and use of chemicals are reduced and water quality is improved.
While it often starts with a leak, historically many utilities have waited until there is an evident problem or rupture to react. Today’s utilities have an option. Imagine being immediately notified about a problem in an main. The EchoShore-TX platform will call, text, or email you promptly after detecting a leak or other anomaly.
As a leading provider of acoustic-based technologies for water loss management, leak detection and pipe condition assessment, Echologics is dedicated to helping water utilities reduce water loss.
