← System Models Infrastructure
What are these models?
Models that simulate the performance and deterioration of physical water infrastructure over time — predicting when pipes, pumps, and treatment works will fail and when to replace them.
What are they used for?
- Predicting pipe failures and bursts
- Planning maintenance schedules
- Optimising asset replacement investment
- Assessing network capacity under growth
Typical inputs
- Asset age, material, and condition
- Historical failure rates
- Operating conditions (pressure, flow, soil)
- Replacement costs
Typical outputs
- Failure risk and probability
- Optimal maintenance schedules
- Investment priority rankings
- Network capacity assessments
Tools & sources
Common tools
- KANEW pipe cohort models
- GIS-based deterioration models
- ISO 55000 asset management framework
