The ApproachThe Approach
� Sharing experience between participants
� International workshop - Identifying Needs and Problems, Brussels 1996
� National workshops e.g. Italy, France, Germany, Finland
� Programme development for future initiatives
Formulating a perspective and set of priorities from
an end user viewpoint
� Problem definition - the managers viewpoint
� Information/data management
� Data acquisition
� Making decisions
Key AreasKey Areas
Problem Definition - The Managers ViewpointProblem Definition - The Managers Viewpoint
� Knowledge of condition and performance still rather limited
� General acceptance of need for increased capital and maintenance expenditure
� Systematic ways of dealing with problems can avoid a serious ‘infrastrucrure crisis’
Problem Definition - The Managers Viewpoint Problem Definition - The Managers Viewpoint (contd)(contd)
� Need indicators of system performance as a basis for rehabilitation planning
� Pipe systems must be assessed in the context of their surrounding environment
� Need to co-ordinate activity on different infrastructure systems
Problem Definition - The Managers Viewpoint Problem Definition - The Managers Viewpoint (contd)(contd)
� Recent developments in Information Technology offer major efficiency improvement opportunities
� Need competent professional management skills to successfully tackle the infrastructure problem

Key PointsKey PointsTowards:-
Active Management
Target expenditure whilst minimising risk of failure
Away from:-
Crisis (or Reactive) Management
This represents a significant change for many countries
Key Points (contd)Key Points (contd)
Need improved enabling technologies to measure and assess performance and condition
Not all problems are associated with older systems
Key Points (contd)Key Points (contd)
Need improved funding mechanisms to transfer experience and know-how between countries
