Optimizing Capital Investment and Reducing Risk Across Massive Transmission Pipeline Networks
Operating 4,027 miles of mains, Fairfax Water faced the challenge of objectively prioritizing over 10,000 large-diameter segments for inspection. The complexity involved identifying optimal rehabilitation timing and minimizing the potential impacts of system failures on property owners and commuters.
GIS-Based Scripting and 100-Year Remaining Service Life Analysis
Our team bridges the gap between raw infrastructure inventory and optimized investment by executing a 100-year remaining service life analysis for all transmission pipelines. Using customized GIS-based scripts, our team develops segment-level risk scores for over 10,000 assets based on more than 30 separate risk factors. The solution incorporates innovative condition assessment technologies, such as electromagnetic inspection and transient pressure monitoring, to provide high-resolution data on pipe condition. These individual risk results are aggregated along transmission "runs" of similar material to calculate consequence and probability of failure rankings for longer sections. By configuring Innovyze InfoAsset Planner with specialized service life curves, our team transforms raw GIS data into placeholders for target renewal years. This tech-enabled strategy allows the utility to program prioritized candidate work directly into their 10-year Capital Improvement Program.
A Scalable Roadmap for Long-Term Transmission Asset Sustainability
The program provides a 100-year planning horizon, allowing Fairfax Water to identify optimal inspection and renewal timing. By installing custom scripts, the organization can now perform risk-based decision-making that reduces system failure impacts for its 2 million customers.
