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.
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.
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.
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.
Airports, as bustling hubs of activity, rely on intricate water infrastructure networks to support their multifaceted operations. During routine resurfacing work, a critical water supply line at this major airport developed a leak, jeopardising the smooth functioning of essential services. The leak posed a serious threat of disruption to flight schedules, passenger services, and the airport’s overall operational efficiency. The urgency of the situation, coupled with the necessity to minimise disruption during peak hours, required a swift and specialised night-work solution.
Recognising the criticality of the situation, the airport turned to Aqua Analytics. Understanding the unique challenges of working within a high-stakes environment like an airport, and with the appropriate security clearances, Aqua Analytics swiftly mobilised. Our approach required:

In the face of drought and increasing water stress, the NSW government recognised the critical need to address leakage and water loss across regional water utilities. The goal was to enhance the utilities’ ability to efficiently identify, target, and repair leaks, ultimately conserving billions of water. The significant challenge required a comprehensive and coordinated effort to tackle water loss in a region facing severe environmental pressures.
To tackle this challenge, the Department of Planning and Environment (DPE) partnered with the NSW Water Directorate and local water utilities to launch the Regional Leakage Reduction Program. Aqua Analytics was selected as a key partner due to its expertise in leak detection and water loss management.
The Regional Network Leakage Detection Project is part of the NSW Government’s $12.5 million Regional Leakage Reduction Program. This initiative has already resulted in more than 15,450 kilometres of water mains being surveyed and over 4,000 leaks being found, saving councils billions of litres of lost water in a year.
The program encompassed three phases over 30 months, focusing on:
The impact of the Regional Leakage Reduction Program has been substantial:
Aqua Analytics played a crucial role in the success of this program and was actively involved in all three phases. Our expertise in leak detection, advanced technology, and collaborative approach enabled the identification and repair of numerous leaks in a relatively short timeframe. Since the award in early 2022, Aqua Analytics has undertaken projects in almost 30 councils, surveying 10,000 kilometres of water mains and finding 3,100 leaks. Our commitment to long-term water conservation efforts in NSW is evident through our extensive involvement and significant contributions.
The Regional Leakage Reduction Program is a testament to the effectiveness of a collaborative approach to water management. Through the combined efforts of the NSW government, local water utilities, and expert partners like Aqua Analytics, significant progress has been made in addressing water loss and improving the sustainability of regional water supplies. This program highlights the importance of innovative solutions, data-driven strategies, and teamwork in tackling the pressing issue of water conservation in the face of environmental challenges.
