Challenge

A district council in the South Island of New Zealand recognised the urgency of addressing water loss within their network, particularly as the summer months approached.

They engaged Aqua Analytics to undertake an intensive active leakage control investigation to ensure a resilient water supply for their community. Our team mobilised within weeks of award and completed the work within a few days.

The project focused on two of the council’s water systems, covering 51 kilometres of water mains. The network presented unique challenges due to a high proportion of non-metallic pipes (uPVC and PE), making leak detection more complex and requiring a skilled team to investigate.

Solution

Aqua Analytics deployed a skilled two-person team equipped with sensitive acoustic equipment to conduct a thorough survey, accessing all available appurtenances and water meters.

Using a GIS-centric approach, Aqua Analytics meticulously mapped and recorded each leak’s location. This spatial data was integrated into the council’s GIS system, enabling swift visualisation and prioritisation of repair works. By accurately pinpointing leak locations, the council could dispatch repair crews efficiently, reducing response times and minimising water wastage.

Measureable Outcomes

The intensive investigation yielded significant results, uncovering a total of 34 leaks, including 30 network leaks and 4 customer-side leaks.

The combined leakage amounted to a substantial 234 liters per minute, translating to a staggering 123 megaliters of annual water loss. Notably, some leaks on mains and ferrules exceeded 20 liters per minute, highlighting the potential for significant wastage over time.

Over 85% of the detected leaks were not visible above ground, underscoring the importance of proactive leak detection in identifying hidden water loss. As the summer months approached, this intervention was crucial in ensuring the community’s water supply remained resilient during periods of peak demand.

Conclusion

Aqua Analytics’ expertise in leak detection and GIS-centric reporting enabled the district council to proactively address non-revenue water challenges in the South Island of New Zealand.

By implementing a targeted and efficient investigation, we identified and quantified significant water loss, empowering the council to take swift corrective action and ensure a more sustainable and resilient water supply for their community.

New Zealand councils are now better equipped to address water loss challenges with the shift to a new funding model under the “Local Water Done Well” initiative. This positive development, coupled with the proactive leak detection services provided by Aqua Analytics, paves the way for improved water network efficiency and sustainability across the nation.

Challenge

A remote community in the Northern Territory was grappling with significant water loss within its network, impacting resource availability and operational costs. The complex network, featuring 27 kilometres of distribution mains (predominantly non-metallic) and 480 customer connections, presented unique challenges for leak detection. High minimum night flow (MNF) measurements indicated significant leakage, and a considerable portion was suspected to be caused by customer-side leaks, which are common in remote communities.

Solution

Aqua Analytics was engaged to undertake a comprehensive water loss audit and investigation program. Leveraging a tailored approach designed for non-metallic pipe networks, Aqua Analytics aimed to identify and quantify water loss, empowering the community to take targeted action. Our methodology included:

Acoustic Inspections: Our experienced technicians conducted acoustic inspections of the entire 27 km distribution network, utilising sophisticated electronic equipment.
Customer Side Leak Focus: A meticulous acoustic and visual inspection of customer water meters was performed, with follow-up investigations to confirm any suspected leaks.

Additionally, all leak reporting was captured spatially with GPS coordinates to assist with easily and accurately identifying defects, which is important in rural environments.

Challenge

The water operator had established District Metered Areas (DMAs) as a crucial component of their water loss management strategy. However, ensuring the effectiveness of these DMAs required verifying their hydraulic isolation from the rest of the network. The operator needed to confirm that boundary valves were fully closed and did not allow water to pass between DMAs, which could compromise their ability to monitor and manage water loss accurately. Additionally, recent water mains augmentation near the boundary had raised concerns about potential cross-connections.

Solution

Aqua Analytics was engaged to conduct a series of zero-pressure tests (ZPTs) across four adjacent DMAs. This involved a comprehensive approach to validate DMA integrity:

Zero Pressure Test Design: Aqua Analytics developed a detailed test plan, strategically selecting locations for pressure monitoring and identifying potential areas for cross-connections or valve leakage.
Nighttime Operations and Monitoring: Aqua Analytics conducted the ZPTs during nighttime hours to minimise customer disruption. Ovarro XiLog pressure monitoring IoT devices were installed at key points within the network, providing real-time data on pressure fluctuations and enabling the team to monitor network performance during the tests. The XiLog devices transmitted data at one-minute intervals via 4G, allowing for continuous monitoring and analysis by the project team. Access to the data was also provided to the client via a secure cloud server.
Boundary Valve Assessment: The tests focused on confirming the full closure of boundary valves, a critical factor in ensuring DMA isolation. Any valves found to be leaking or partially closed were addressed to maintain hydraulic independence.
Data Analysis and Reporting: Aqua Analytics analysed the collected data to assess the integrity of each DMA's hydraulic isolation. A detailed report was provided to the client, including recommendations for remedial actions, such as valve repairs or replacements.

Results

Confirmed DMA Isolation: The zero pressure tests successfully confirmed the hydraulic isolation of most of the tested DMAs, validating their effectiveness for water loss management purposes.
Identification of Undiscovered Valves: The project uncovered additional valves that were not fully isolated, allowing the client to address these issues and further improve DMA integrity. The client had a strong identification system for boundary valves and undertook these works as a priority.
Enhanced Network Understanding: The real-time pressure monitoring data provided valuable insights into the network's behaviour during the ZPTs. This ensured that the field team, at various locations at night, could all see the same data in real time.

Client Benefits

Improved DMA Performance: By verifying the hydraulic isolation of DMAs and addressing any identified issues, the client could optimise their water loss management strategies and have improved confidence in the data coming into their central event management system.
Reduced Non-Revenue Water: The project contributed to a reduction in non-revenue water, leading to cost savings and improved resource management.
Increased Operational Efficiency:The accurate assessment of DMAs allowed the client to focus their leak detection and repair efforts more effectively, maximising efficiency.
Enhanced Network Resilience: By addressing valve issues and improving DMA isolation, the client increased the resilience of their network to leaks and other disruptions.

Conclusion

Aqua Analytics’ zero pressure testing project played a vital role in ensuring the effectiveness of the water operator’s DMA strategy. By confirming hydraulic isolation and providing actionable insights, the project empowered the client to proactively manage water loss, improve network efficiency, and ensure a reliable water supply. Clients should undertake ZPTs regularly to ensure boundary valves are not compromised by third parties or in the ordinary operation of their business.
