Summer in Australia and New Zealand presents a unique challenge for water infrastructure, particularly with increasing water main breaks. In this blog post, we delve into the reasons behind these breaks and explore practical strategies such as pipeline condition assessment, pressure transient monitoring, and active leak detection to mitigate these issues.
Active leak detection involves regularly inspecting the water distribution system to identify and repair leaks before they lead to major breaks. This proactive approach uses technologies like acoustic sensors and correlators to detect the sound of water escaping from the pipes, which also helps reduce non-revenue water and operate more efficiently.
This involves evaluating the current state of the water distribution infrastructure to prioritise maintenance and replacement. Pipeline condition assessment technologies such as Dynamic Response Imaging, electromagnetic inspection and wall thickness measurements are widely used all year round to help water authorities proactively repair, replace and rehabilitate sections of water mains at risk of failure.
Pressure transients are rapid changes in pipeline pressure caused by operations like pump startups, network operations, or large customer usage profiles. Monitoring these transients helps identify conditions that may lead to pipeline failures, allowing network calming initiatives to be initiated.
Implementing real-time pipeline monitoring systems allows for immediate detection and response to abnormal conditions in the pipeline network — such as when a burst occurs. This includes monitoring flow rates, pressure transient, and even the chemical composition of the water.
In addition to proactive measures to prevent water main breaks, having a rapid and efficient reactive response plan is crucial, especially during the challenging summer months in Australia and New Zealand. Here are some strategies to ensure a faster reactive response to such incidents:
With the challenges posed by summer conditions in Australia and New Zealand, especially with ageing infrastructure like cast iron and ductile iron pipes, adopting a proactive approach to pipeline management is essential. Techniques such as active leak detection, pipeline condition assessment, pressure transient monitoring, and real-time pipeline monitoring play a crucial role in reducing water main breaks and ensuring the reliability of water supply systems. These strategies not only enhance the efficiency of water distribution but also contribute to sustainable water management in these regions.

In the contemporary landscape of water management, addressing Non-Revenue Water (NRW) is imperative for ensuring sustainable and efficient service delivery.
NRW represents the water that has been produced but is lost before it reaches the consumer. Such losses can either be physical, through leakage, or apparent, due to theft or meter inaccuracies.
In Australia, where water is a precious resource, tackling NRW is paramount. This article sheds light on Non-Revenue Water’s intricacies in Australia, offering insight into effective water loss management and leakage reduction strategies.
Non-Revenue Water encompasses three core components:
Elevated levels of Non-Revenue Water can significantly impact a water utility’s financial health and service delivery. It denotes inefficiencies leading to resource wastage, heightened energy consumption (and thus, increased carbon emissions), and increased operational costs.
Moreover, high NRW levels intensify water scarcity, especially in drought-prone regions like Australia.
Implementing robust leakage detection and repair programmes is pivotal for reducing physical losses. Modern technologies like acoustic leak detection and real-time acoustic loggers can substantially enhance leakage management efforts.
Transitioning to AMI can drastically diminish apparent losses by improving meter accuracy and facilitating real-time monitoring of water consumption patterns.
Effective pressure management can mitigate the risk of pipe bursts and leaks, thereby reducing physical losses.
Fostering public awareness about the significance of water conservation and the implications of NRW can engender a culture of accountability and prompt reporting of leaks and unauthorised usage.
Establishing a conducive policy and regulatory environment is crucial for incentivising NRW reduction and promoting efficient water management practices.
Adopting a proactive approach towards asset management and maintenance can extend the lifespan of water infrastructure and minimise the incidence of failures.
Utilising data analytics and smart water solutions can provide insightful diagnostics on system performance, enabling timely interventions and informed decision-making.
Australia’s water utilities have been at the forefront in embracing innovative water loss management and leakage reduction techniques (for instance, the NSW Government has embarked on a Regional Leakage Reduction Project). Significant strides have been made in reducing water network leakage through concerted efforts involving public engagement, technology adoption, and policy formulation. For instance, deploying acoustic sensors and smart water metering systems has facilitated early detection and rectification of leaks, substantially reducing NRW levels.
Addressing Non-Revenue Water is a multifaceted challenge requiring a holistic and technologically-driven approach. By adopting strategic measures and fostering a culture of continuous monitoring and improvement, it is possible to reduce NRW levels significantly.
This ensures the financial viability of water utilities and contributes towards a sustainable and water-secure future. Through collective effort and robust water loss management strategies, Australia can continue leading the way in tackling Non-Revenue Water challenges, setting a precedent for other regions grappling with similar issues.

The concept of Non-Revenue Water (NRW) is fast becoming a central concern for water utility management worldwide. Understanding and reducing NRW has benefits, from financial sustainability to compliance with emerging regulatory standards. In this blog, we will unpack various aspects surrounding NRW, its impact on utility management and why it’s more important than ever to focus on this aspect.
One of the most immediate and apparent impacts of NRW is on the financial health of a water utility company. NRW consists of water that is lost before it reaches the customer, mainly due to leaks, theft or meter inaccuracies. Reducing these losses has a direct effect on cost-saving. Funds previously allocated to address these issues can be redirected to other vital areas, leading to more efficient utility management.
Technological advances offer potent tools for identifying and reducing NRW, enhancing the efficiency of utility management. The use of technologies like smart meters and SCADA systems not only pinpoint the issues but also help in quick resolution, making the utility operations more streamlined.
Regulatory standards concerning NRW are becoming more stringent. Failing to meet these standards can result in fines and penalties, adding an additional financial burden on utilities. Beyond that, there’s a push towards responsible water management as a part of broader sustainability goals. Meeting these standards is now an integral aspect of effective utility management.
Regular maintenance, including the use of corrosion-resistant materials, pressure management systems and immediate response to leaks, plays a pivotal role in mitigating water loss. Scheduled pipeline inspection and assessment technologies, such as wave generation, acoustic propogation and a range of sensors can be a part of proactive maintenance protocols.
Regular calibrations and timely replacements of water meters are equally important. Faulty water meters can lead to incorrect billing and unaccounted water loss.
Effective asset management, from pipe maintenance to the metering infrastructure, is a cornerstone in reducing NRW and, thus, in efficient utility management.
Ignoring NRW not only has financial implications but also significant environmental costs. Leaks and losses mean more water needs to be sourced and treated, increasing the carbon footprint. Reducing NRW thereby contributes to both environmental sustainability and efficient utility management by reducing energy use in pumping lost water throughout complex water systems.
Summary: This case study exemplifies how the integration of smart metering technology can not only drastically reduce NRW but also make utility management more efficient and environmentally responsible.
Summary: Investing in automated leak detection and smart water sensors has proven transformative, achieving remarkable NRW reduction while enhancing overall utility management.
Reducing NRW serves as a forward-looking strategy for water utilities. As resources become increasingly scarce, having a lower NRW rate equips a utility to face future challenges more robustly, including potential water shortages. This is even more relevant as we enter a period of sustained climate change where periods of drought are anticipated.

In the quest for improved water leakage management, pressure transient monitoring has emerged as an effective strategy. This approach provides a thorough understanding of water systems, enabling us to reduce water loss effectively. In this blog, we will explore the intricacies of pressure transient monitoring and its significant role in water conservation in our drinking water systems.
Pressure transients, also called water hammers, are abrupt variations in water pressure within a system. If left unchecked, these changes can significantly damage pipelines, potentially causing catastrophic failures. Pressure transient monitoring allows for rapid detection of these potentially damaging high-speed pressure changes in the pipelines under our cities and towns. Key aspects that make pressure transient monitoring a critical tool in water management include:
Understanding the mechanism behind pressure transients or water hammers can help understand why monitoring them is critical. When the flow of water is abruptly stopped or changed, it creates a sudden shift in momentum. It causes a wave of high pressure to ripple through the system. This phenomenon is known as a pressure transient. Such events can be triggered by various factors, such as:
Pressure transient monitoring devices are critical elements in detecting and managing water hammers in reticulation networks. These devices are designed to measure sudden pressure changes and relay this data for analysis via cellular communications and cloud servers. Key features of these devices include:
