Intelligent Assets - Condition and Performance Monitoring Techniques

Reference: 18/RG/05/49
ISBN: 1 84057 850 5
Published Date: 09/05/2018

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.

Consistency of Reporting Performance Measures

Reference: 17/RG/04/5
ISBN: 1 84057 834 3
Published Date: 10/07/2017

Water companies have been working together, coordinated by Water UK and supported by Ofwat, to develop more consistent reporting methodologies for the measurement of leakage, supply interruptions and sewer flooding.

As part of this work Water UK requested UKWIR commission an independent review and challenge of the initial proposals, to provide assurance and to develop more detailed guidance.

UKWIR commissioned Atkins to carry out this review, working with company practitioner experts and a steering group including representation from companies, Ofwat,  the Environment Agency, the Consumer Council for Water and Water UK.

Ofwat has confirmed that the output of this project will not impact on PR14 PCs and ODIs. It is intended to form the basis of public reporting from 2020/21 and to inform the development of PR19 Business Plans, and the detailed reporting guidance documents are below.

Resilience – performance measures, costs and stakeholder communication

Reference: 17/RG/06/4
ISBN: 1 84057 833 5
Published Date: 06/07/2017

This report is a further step in the evolution of work undertaken by the water industry related to the concept of resilience. The work focusses on the service provided by the water supply and wastewater sectors and how aspects of resilience of that service could feed into Periodic Review 2019. The work also draws on the parallel work of the Water and Wastewater Resilience Action Group (WWRAG).

The report desribes different ways of looking at resilience and how resilience can be expressed in terms of Outcomes and so contributes to Ofwat's consideration of possible resilience metrics that could be used to set Performance Commitments and Outcome Delivery Incentives.

The report gives a structured and practical approach to the development of resilience metrics appropriate to a range of business purposes and technical types, with specific reference to stakeholder communication. Candidate metrics for each of the two water sector services are listed.

Water company benchmarking

Reference: 16/RG/07/38
ISBN: 1 84057 808 4
Published Date: 10/02/2016

This report outlines a methodology for benchmarking performance in the UK water sector. The methodology addresses legitimate concerns over the application of benchmarking in the current regulatory climate, but also enables the benefits of benchmarking to be realised. In addition, the report sets out a set of 50 key performance indicators (KPIs) (broken into 23 ‘main’ customer focused KPIs and 27 ‘secondary’ more technical KPIs) which could be used to benchmark performance. If applied, the methodology and the KPIs could create a more open and transparent sector, leading to improved regulation of companies, drive performance improvements and ultimately, better service to customers.
