Data61 is using data-driven techniques to improve prediction of pipe failures for water utilities. Intelligent predictions reduce maintenance costs, prioritise capital spend and minimise disruption to water supplies and the community.
The Challenge and Data61’s Approach
Australian water utilities currently spend $1.4 billion per year on reactive repairs and maintenance, including the consequence cost of social and economic impact. Focusing the asset maintenance efforts on preventative repairs has the potential to save the water industry $700 million on reactive repairs and maintenance.
Condition assessment of water pipes is an expensive and disruptive process with water utilities typically inspecting only 1% of their network assets per annum. Data61 has developed an advanced failure prediction tool using non-parametric machine learning techniques; with this we expect to double the precision of prediction within that 1% of the network that is inspected.
Data analysis completed for:
- 23 global utilities
- 700,000 failure records
- 9 million pipe assets
- 525,000 kms of pipes.
