Ewan relevant capabilities l.jpg
Ewan – Relevant Capabilities

In the past two years our track record has included:

  • Strategic investment planning - a new approach that integrates & optimises the investment drivers

  • Capital maintenance planning - extensive support to a number of water companies, including application of specialist tools and services

  • Process review - for asset rehabilitation, asset regime & capital investment programme – and identification of business improvement opportunities

  • Supply demand planning - best practice approaches to capacity investment & leakage management economics


Investment planning and delivery how should we approach it l.jpg
Investment Planning and Delivery – how should we approach it?

  • For AMP3: frantic activity to develop PR99 Business Plan …

  • …but then it ‘stopped’ (little connection between planning and implementation)

  • For AMP4: With PR04 submitted, aim for

    • Ongoing and supportable Common Framework-compliant approach to prioritise investments and spends

    • Delivery of AMP5 planning (PR09 Business Plan) at the ‘press of a button’


Other desirable characteristics l.jpg
Other desirable characteristics… it?

  • Delivery of ‘Best Value’

    • Deliver required serviceability at least Whole Life Cost over the planning horizon

  • Pragmatic

    • Make best use of existing data and systems

    • Useable by Water Company staff

  • Cost-effectiveness of implementation

    • Avoid having to spend a fortune on ‘bloody consultants’!


One way to approach it l.jpg
One way to approach it… it?

  • Bottom-up, all-encompassing software tools which provide both the strategic plan and maintenance programmes for every individual main

  • Gives reassuring comprehensive output – but is it really appropriate?

    • Large data overhead – expensive!

    • Implies unrealistic precision

    • Size and complexity hinders transparency, auditability

    • Likely to require excessive maintenance and updating

    • Leaves little room for on-the-ground ‘knowledge’ judgements


Another way l.jpg
Another way … it?

  • Break down the problem – three levels

  • Strategic model – Business Plan development

    • Intervention budgets and targets

    • Allocation by broad ‘Asset Groups’

  • Risk Prioritisation model

    • Asset level (DMA) – complete company coverage

    • Focus on areas for improvement

  • Detailed tools

    • Identify robust site-specific solutions using innovative technology




Slide11 l.jpg

High level infrastructure FMEA model it?

Matrix underpins both strategic and prioritisation processes


Level 2 risk prioritisation l.jpg
Level 2 – Risk Prioritisation it?

  • Inputs:

    • Supportable intervention/ investment levels across Asset Groups from Level 1

    • Cause & Effect and other models consistent with Level 1

  • Outputs:

    • Focus on assets where detailed optioneering is required

    • Prioritised list of assets requiring interventions

Models

Outputs

Improve-ments

Strategic

Asset aggregation  high-level groups

Strategic Guidance – investment scale and focus

Regular re-run with evolving relationships and drivers

Level 2:

Risk Prioritisation

Asset Characterisation at e.g. DMA level

Cause & Effect, Deterioration, Risk, Impact, Cost

Review prioritisation of non-committed schemes

Initial prioritisation (risk only)

Level 3:

Detailed

Corporate GIS

Optimal, costed scheme identification

Detailed model formulation

Programme

Monitor

Implement

Update


Slide15 l.jpg

Conclusions it?

  • Evolving regulatory system: places new pressures on Investment Planning and Delivery methods.

  • Water Companies need to invest in new technology - pragmatic but effective tools to plan, prioritise and deliver capital maintenance investment programmes

  • The IPAD approach we recommend:

    • Start ‘top-down’ – based on accessible asset information

    • Focus detailed investigation in those areas which need it

    • Use consistent data and models for planning at all levels

    • Apply appropriate technology to find the right solutions

  • Benefits:

    • Achieve technical efficiencies in delivery

    • Streamline future Business Plan development
