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
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
Other desirable characteristics…
  • 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
One way to approach 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
Another way …
  • 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

  • Inputs:
    • Supportable intervention/ investment levels across Asset Groups from Level 1
    • Cause & Effect and other models consistent with Level 1
  • Outputs:

Conclusions

  • 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
