The Challenge
This Regional Water Utility faced the need for a fast, non-invasive method to assess the condition of a 300mm asbestos cement (AC) water main. The primary objectives were to:
- Locate leaks requiring immediate repair
- Identify areas of concern for future maintenance or replacement.
- Evaluate the suitability of Dynamic Response Imaging™ (DRI) technology for broader pipeline assessment within their network.
Our Solution
The client engaged Aqua Analytics to conduct a pipeline condition assessment using KenWave’s DRI technology. This innovative acoustic solution offered a non-disruptive approach to evaluate the pipeline’s structural integrity without requiring costly and time-consuming excavations. The process involved:
- Data Collection: A team of Aqua Analytics technicians utilised portable DRI equipment to record acoustic signals along the pipeline at predetermined access points.
- Data Analysis: The collected data was securely transmitted to KenWave for analysis using proprietary algorithms that assessed pipe stiffness, identified leaks, and pinpointed areas of potential weakness.
- Reporting: Aqua Analytics provided the client with a comprehensive report detailing the pipeline's condition, including a stiffness profile, leak locations, and recommendations for further action.
Results
- One-Day Assessment: The entire assessment process, including data collection, analysis, and reporting, was completed within a single day, minimising disruption to the water supply system.
- Validated Accuracy: The client excavated a section of pipe for independent laboratory testing. The results strongly correlate with Aqua Analytics' DRI assessment and measured wall thickness, validating the technology's accuracy.
- Client Satisfaction: The client was highly satisfied with the efficiency, accuracy, and non-invasive nature of the DRI assessment, confirming its alignment with their needs.
Client Quote: “In our minds, the DRI results and the validation testing align.”
Key Benefits
- Rapid Assessment: DRI technology enables quick pipeline condition assessments without requiring extensive excavations or service disruptions.
- Accurate Results: DRI provides reliable data on pipe stiffness, leaks, and potential weak points, facilitating informed decision-making regarding repairs and replacements.
- Cost-Effective: DRI's noninvasive nature reduces the costs associated with traditional assessment methods, making it a budget-friendly solution for water utilities.
Conclusion
The successful implementation of DRI technology showcases the power of innovative solutions in addressing the challenges of aging infrastructure. The rapid, accurate, and non-disruptive assessment gave the client valuable insights into their pipeline’s condition, empowering them to proactively manage their assets and ensure reliable water service for their community.
