Real-Time Leak Detection Archives

Challenge

The client recognised the need for proactive leak detection within their water distribution network but faced budgetary constraints that hindered the purchase of the most advanced acoustic logging equipment. Having tried several brands, they approached Aqua Analytics for brand-independent advice about equipment performance.

They required a cost-effective solution that would allow them to leverage the latest technology without significant capital expenditure.

Solution

Aqua Analytics offered a fully managed acoustic logger deployment service, providing the client access to state-of-the-art equipment and expertise without any upfront capital outlay. All IoT devices were owned by Aqua Analytics and provided under long-term rental arrangements. This turnkey solution included:

Provision of Aqua-Owned Assets: We supplied the client with high-quality NB-IoT acoustic loggers from our own fleet, eliminating the need for the client to purchase expensive equipment. These loggers utilise the Spark NZ Narrowband Internet of Things (NB-IoT) network for reliable and efficient data transmission.
Remote Setup and Support: Our team of experts remotely configure and set up the loggers in the cloud environment, ensuring seamless integration with the client's existing systems via REST APIs. Cellular costs associated with data transmission are covered by Aqua Analytics, simplifying procurement and management for the client. Ongoing technical support is provided throughout the project.
Daily Data Review and Analysis: Our dedicated team monitors the loggers data daily, analysing acoustic signals for signs of leaks and reviewing Artificial Intelligence (AI) predictions. This proactive approach enables reduced leak run times and swift response.
Detailed Reporting and Recommendations: The client receives daily reports detailing leak locations, estimated water loss, and recommended actions. These insights empower the client to prioritise repairs and optimise their maintenance strategies.
Flexible Deployments: The loggers can be easily relocated within the network to target specific problems areas or investigate DMAs with high minimum night flows (MNFs).

Results

Zero Capital Expenditure: The service delivery model eliminates the need for upfront investment in advanced hardware, making it a cost-effective solution for the client.
Significant Reduction in Water Loss: The early detection and repair of leaks, which was supported by Aqua Analytics' fully-managed service, has resulted in substantial water savings for the client.
Access to Expertise: The client benefited from Aqua Analytics' extensive knowledge and experience in leak detection and water network management, and our daily use with a large range of acoustic logger equipment.

Client Benefits

Cost-Effective Leak Detection: The zero-capex model provided the client with access to cutting-edge technology without the burden of upfront costs or complex procurement processes.
Proactive Water Loss Management: The daily monitoring and alerts enabled the client to address leaks promptly, minimising water leakage and potential damage.
Flexibility and Efficiency: The ability to relocate loggers within the network allows for targeted investigations and optimised resource allocation.
Expert Leak Detection Support: Aqua Analytics' dedicated team provided comprehensive support, from initial setup to ongoing monitoring and analysis, ensuring the client received maximum value from the service.

Conclusion

Aqua Analytics’ fully-managed acoustic logger deployment service demonstrates how innovative solutions and a service-oriented approach can help revolutionise leak detection for water utilities.

By offering a zero-capex model with access to cutting-edge acoustic loggers and NB-IoT connectivity, we empower clients to proactively manage their water networks, significantly reduce water loss, and achieve greater operational efficiency.

Our dedicated team handles all deployment, monitoring, and analysis aspects, providing actionable insights and seamless integration with existing asset management systems.

This turnkey service minimises the financial burden and ensures clients receive the full benefits of advanced acoustic leak detection technology. As water utilities continue to seek cost-effective and efficient solutions to combat non-revenue water, Aqua Analytics’ fully-managed acoustic logger deployments represent a powerful tool in their arsenal, as this New Zealand client demonstrates.

Challenge

The client was tasked with horizontal directional drilling (HDD) operations in close proximity to critical water mains. The water utility asset owner mandated a proactive monitoring solution to prevent damage and ensure the integrity of their infrastructure throughout the construction process.

Solution

The client partnered with Aqua Analytics to implement a personalised asset monitoring system leveraging the power of Narrowband Internet of Things (NB-IoT) technology for reliable data transmission and communication. The solution included:

NB-IoT Devices: Strategically placed sensors continuously monitored the condition of the water mains, even when located 1.5 meters underground and beneath 25-millimeter steel road plates.
Automated Alerts: Daily SMS and email alerts provided the project team with real-time insights into the status of the water mains, enabling immediate response to any potential issues.
Monitoring-as-a-Service: Aqua Analytics managed every aspect of the project, from device deployment and data collection to analysis and reporting.

Results

Zero Capital Outlay: The monitoring-as-a-service model eliminated upfront costs for the client.
Fully Managed Solution: The client's project team received comprehensive reports daily, including weekends, without allocating additional resources to the monitoring process.
100% Data Reliability: The robust NB-IoT technology ensured consistent and accurate data transmission despite the challenging underground environment.
Zero Damage to Water Mains: The Aqua Analytics solution demonstrated that the HDD operations did not compromise the water mains.

Client Quote: “We entrusted Aqua Analytics with monitoring several water mains during our two-week HDD project. Their daily reports gave the water utility the assurance they needed, confirming our work caused no damage. We will definitely use Aqua Analytics again in the future.”

Client Benefits

Risk Mitigation: Proactively addressed concerns about potential damage to critical water infrastructure.
Cost-Effectiveness: The monitoring-as-a-service model provided a comprehensive solution without requiring significant capital investment.
Peace of Mind: The client's team could focus on their core construction tasks, confident that the water mains were continuously monitored and protected.

Conclusion

Aqua Analytics’ innovative monitoring solution allowed the client to successfully execute their HDD project while upholding the highest standards of environmental responsibility and stakeholder collaboration. This case study exemplifies the power of technology in safeguarding critical infrastructure and ensuring the smooth completion of complex construction endeavours.
