Monitoring of critical assets can provide an early warning of possible failure, allowing early intervention and avoiding or mitigating impacts on customer service. Various ‘Condition and Performance Monitoring Techniques’ (CPMT) exist for this purpose, such as vibration or acoustics measurement, as well as analytical techniques (e.g. processing data to identify trends or detect anomalies). There is a need within the water industry to better understand the CPMT options available and their potential benefits.
Alternative options for CPMT were identified and assessed through a review of published literature. Water companies and CPMT supplier companies were also surveyed on their experiences of CPMT, in order to understand the usage/availability of various types of CPMT, and the success of CPMT implementations.
A framework for CPMT selection was devised based on identifying priority assets where CPMT would be most likely to be beneficial, then shortlisting potential techniques for these assets, and finally evaluating the costs and benefits. The costs and benefits section of the framework is illustrated via generic cost-benefit assessments for a range of common water industry asset types, provided in spreadsheet format on a CD accompanying the project report.
The project included a number of studies to quantify the benefits of CPMT. Data suggest that in many cases there are indeed clear benefits (more than justifying the cost of the CPMT) but the conclusions that could be drawn were restricted by data quality and availability.
One of the outputs from this project was a generic cost-benefit assessment spreadsheet, which provides cost-benefit assessment calculations and realistic quantities relating to asset deterioration rates, asset failure/repair costs etc, for ten commonly used water industry asset types. This spreadsheet might be useful in gauging the potential benefits of CPMT; users can also refine the analysis inputs in order to better represent particular assets at their company.
This spreadsheet is included on the CD. Further explanation and guidance is included within the spreadsheet itself.
