'Service to customers' is the key measure by which future capital maintenance needs will be determined in the UK. Deterioration of the condition and associated performance of the asset base will impact on this service to customers. Therefore, water undertakings, seven of which participated in this project, need to demonstrate how service to customers will be affected over the future period and model the impact of preventative capital investment.
This work linked condition and performance and modelled the impact of asset deterioration on service to customers by a) defining key parameters to be monitored, b) developing a methodology for assessing asset criticality economic levels of maintenance, c) producing simple generic cost models, and d) generating a database of asset life cycle (replacement/refurbishment) cost and frequency.
- Tools for quantifying capital maintenance that are robust and meet regulatory criteria for justifying investment
- Tools that link deterioration processes to performance, failure probability and impact
- Methodology that supports internal business planning needs, enabling prioritising and targeting of investment.
