Challenge
The client faced a critical challenge in protecting third-party water infrastructure during construction. A DN100 cast iron water main ran through the construction zone, posing a risk of damage and potential service disruptions. The client sought a proactive solution to monitor the water main’s condition before, during, and after construction, mitigating the risk of leaks and ensuring the asset’s integrity. Additionally, the client needed to satisfy the asset owner, Sydney Water, that the methodology was sound and appropriate for the asset.
Solution
Aqua Analytics was engaged to provide a comprehensive acoustic monitoring and advisory service designed to safeguard the water main throughout the construction project. The solution encompassed:
- Pre-Construction Leak Detection Inspection: Aqua Analytics conducted a thorough leak detection inspection of the water main before construction commenced. This involved using sensitive acoustic microphones and correlators to pinpoint any existing leaks, ensuring that the asset was in optimal condition before the start of construction activities. No leaks were identified.
- Continuous Acoustic Monitoring: Aqua Analytics deployed a network of acoustic noise loggers along the water main. These loggers continuously monitored the pipeline for leak noise during construction.
- Real-Time Data Analysis and Alerts: The loggers transmitted data via NB-IoT technology to a cloud-based platform, which was analysed using advanced algorithms. This allowed Aqua Analytics to detect and localise any new leaks that might develop due to construction activities, providing real-time alerts to the client for immediate action.
- Daily Analysis and Reporting: Aqua's team reviewed all data daily, and results were sent automatically from our platform via SMS and email.
Results
- Successful Protection of Critical Water Asset: Continuous acoustic monitoring and expert advisory services ensured that the water main remained in optimal condition throughout the construction project, preventing leaks or damage.
- Real-Time Leak Detection: Aqua Analytics' real-time alerts enabled the client to respond quickly to emerging leaks, minimising water loss and service disruptions.
- Improved Asset Management: The detailed data collected during the monitoring period provided valuable insights into the water main's condition, enabling the client to make informed decisions regarding future maintenance and rehabilitation.
- Asset Owner Peace of Mind: Aqua Analytics' proactive monitoring and expert advice gave the asset owners peace of mind, as they knew their critical water asset was protected during the construction project.
Client Benefits
- Risk Mitigation: The project significantly reduced the risk of water main damage and service disruptions caused by construction activities.
- Cost Savings: By preventing leaks and ensuring the long-term health of the water main, the project contributed to cost savings through reduced repair expenses and minimised water loss.
- Proactive Asset Management: The project's data-driven insights enabled the client to develop a more effective asset management strategy, prioritising maintenance and investment for optimal performance.
- Environmental Stewardship: The project supported the client's commitment to environmental responsibility and sustainable resource management by minimising water loss.
Conclusion
Aqua Analytics’ comprehensive acoustic monitoring and advisory services were crucial in safeguarding a critical water asset during a high-risk construction project. By combining advanced technology with expert analysis and proactive recommendations, Aqua Analytics empowered the client to protect their infrastructure and ensure a reliable water supply for their customers.
